Rebuilding the OMP oil injection lines
I was helping MRX Rotary with getting to his aux port sleeves (another story all together). We got to the intake manifold oil injector removal. We no more than breathed on the injector lines (yes, both of them). They both cracked-off the banjo fittings right at the tip of the barb. Brittle. Suddenly, we had another problem to fix.
Cause of failure? My opinion - the oem tubing is marginal at best of heat toleration. Perhaps they're nylon. Not much better than 200 degrees F. material.
Ok, so, this is what I have selected to use. Both the tubing and clamps were found online at http://www.corbincorp.com which is MSC Industrial supply Co.
1) Tubing: MSC # 48701031 available in 10' lengths. Perfect length - still have about 3-4' to spare. 1/8 x 3/16 (CTL) Teflon PFA - Industrial. Translucent. 1/8" I.D., 3/16" O.D.
PFA Characteristics
• Excellent abrasion & temperature-resistance
• Low coefficient of friction for ease of flow
• UV & Gamma radiation stable, chemically inert
• Thermally superior to most plastics
• Outstanding chemical & electrical properties
• Durometer=shore D 55±5
• Temperature range: -320°F to +500°F
$1.51 per foot x 10' = $15.10
2) Clamps: MSC # 48547962. Two-Ear Clamps
Type: 2-Ear
Nominal Size: 1/4
Inner Width of Ear: 0.118 In.
Thickness: 0.0276 In.
Width: 0.236 In.
Material: Stainless Steel
$.33 ea. x 12 = $4.00 (yeah, only needed 8, but that's only if you don't booboo. I got 4 spares.
Wanna buy em?)
OK, I splurged a tad here - could have gotten zinc plated @ .19 ea. Woooo!
Some pix:
So, what's wiring tool doing here? It made the perfect crimper for the clamps! Just do one side at a time. Not all at once. Just a small squeeze at a time, then the other side, back, etc. Finally, the clamp goes fully squished and is gripping the teflon tube so hard, it's hard to rotate anything anymore!

Okay, so here are a couple sketches of the lines in there.
I added 1" to the measured lengths. It's a thing I do when I can. Dunno why really, other than I hate being too short. Those lengths are written on the setch at the pump.
How to reclaim the banjo fittings: Patience!!!!!!
1) GRIND-OFF just enough of both ears of the clamp ring, and it will come (fall?) apart in two halves. I got a bench grinder which most would consider a toy. It was perfect.
2) Whittle-away at the plastic tubing WITHOUT MESSING-UP THE METAL BARB!!!...PATIENCE!!!!!
That's about all there was to that.
Putting the tubing onto the banjo fitting barb: Patience!!!!!!
Just push it on with steady force - NOT TOO MUCH THOUGH!!! Twisting it while pushing really does help a lot. A little spit or something is good to lubricate it some. A paper towel helped me to grip the teflon tubing, and helped to keep me from crushing it in the process...
I did 8 out of 8 without a screw-up, so it can't be that hard...
Let me just make this perfectly clear: DON'T FORGET TO SLIDE A BAND CLAMP ONTO THE TUBE BEFORE YOU PUSH THE SECOND FITTING ON!!!!

Some pix of the (almost) completed project. (Still waiting on a parts order for the aux. port sleeves...)
The two loose ends go to the intake manifold injectors, when they get put back on.
Note how I marked them I, II, III & IIII to coincide with my sketch numbering system.
Well, that's all I can think of. I like to write-out anything I can think of. Not trying to insult anyone's intellegence with being overly detailed. I just hate not having the info that I need AFTER I commit to a project like this!
I think I spent more time just looking for the right materials, and ordering the stuff, than the time that I spent doing the actual work.
Hopefully you know of someone like me who works at a place that regularly buys from MSC. We recieve our orders next-day from their Allanta location. Nice.

That tubing is pretty cool see-thru so you can see the oil and stuff. But yea, what kind of pressures can it take? braided lines can take almost anything, but cost a shitload. I spose if the see-thru ones that you have are better than the stock ones, then its all good.

I can say that I have more than a lot of experience with your garden variety polyethylene tubing which is used everywhere in industrial pneumatics. That stuff is rated for 125 or 150 psi. This teflon tubing seems to me to be just as capable, if not more. It's pretty tuff stuff, hard to just expand it over the barb. It takes a few minutes of steady pushing to finally push it all the way on.
Sorry not to have a number for you on that...

Good find, mine are getting crunchy. I priced replacements the other day and nearly soiled myself. I have to agree that teflon is superior. I work in a chemical plant, and the instrument techs use it on their pressure calibrators. That o.m.p. can't put out too much pressure or mine would have already disintegrated.

Do you (or anybody) know what kind of operating pressure they will see? I thought I read somewhere that the pressure is like real low...
But, yeah, ok, I'll call tomorrow...

Side note: See the vacuum line above the front chamber injector - the one with a big wedgie chunk out of the end of it? Found it that way, and yes, it wasn't even connected at all!!! Good thing he was at least using MMO. He hasn't put more than 1000 miles on it snce he bought it from a guy in Charleston...
edit: Oh, never mind, I just realized I didn't post that pic.
![Smilie](https://www.rx7club.com/images/smilies/smile.gif)
And yeah, the primary mode of tubing failure here is heat degradation. I'll call tomorrow though, if just for kix...

Well, OK, if you insist.
It's the vacuum line right in the middle of the pic. It was supposed to be for the front camber oil injector. It's rotated around from its position when connected. See the big missing chunk?
It was laying to the side of the injector, not even close to being connected to it. It also was most likely ruining the level of vacuum in the other lines! And , yes, there was a suspicion that the vacuum system had a nasty leak before this work began. This little sucker is really hidden big-time when the engine is all-together, you know...
Also, you can see more of the teflon lines in this pic too...
Another tip I just now remembered that I didn't include above, assemble the longest lines first. That way, if you booger-up an end while trying to push the tubing onto the banjo barb, you can re-cut it to a shorter length and still use it. (Not that I had to, of course
)

those braided steel lines are 100$ for a set, as in 2, so 200$ for braided lines that can withstand pressures of like 10000psi or some **** for a device that never puts out more than 100psi... what a waste.
I think I'll stick to that clear **** or the stock ones..

Excellent write-up BTW. It's great to see high-quality, low-cost solutions to common problems. People need to see there are often much cheaper solutions than going straight to an automotive or rotary specialist.

When I replace my injectors, this is something I'm definatly going to do.
I don't know if my lines or my OMP is getting clogged up, but I'm definatly not burning as much oil as I should.
Is it difficult to remove the OMP and the actual injectors without messing anything up? I figure while I have my UIM off and are doing the injector work, I muight as well pull the oil injection system apart and clean the whole thing out. What would you guys suggest as a cleaning agent?

"PFA perfluoralkoxy
PFA was developed by DuPont as a High Temperature Teflon® with a maximum operation temperature of 500°F (260°C), while maintaining similar properties to other fluoropolymers. Of course this added temperature resistance also adds a significant increase in cost. The most common brand names include DuPont Teflon® PFA and Saint-Gobain Norton® PFA."
MSC also sells the same stuff with the Parker name. It's # 79249595 but is sold only in 50' lengths @ $56.84 (good price if you want that much).
• Chemically inert to nearly all industrial chemicals and solvents
• Translucent and flexible
• Nonstick smooth surface
• 100% Pure PFA resin used, FDA compliant
• Nonflammable
• UV and weather resistant
• Color: natural
• Sold in standard coil 50 ′ lengths only
This Parker tubing is rated at 249 psi.
The tubing that I first posted is made by Saint-Gobain Norton. Pressure rating of that particular size was not known by those present @ Norton, and the guru is out of the office roday. The 1/8 I.D., 1/4 O.D. stuff is rated @ 419 psi @ 73 degrees F. So, the thinner walled 1/8 I.D., 3/16 O.D. stuff is probably the same as the Parker tubing. Of course, pressure rating of fluoropolymer tubings go down significantly as the temperatures go up, so...
You can play with the following broshure if you want... http://www.tygon.com/Media/Documents...P-PFA-PTFE.pdf

That is the best writeup on oil metering lines ever on any of the three most popular RX forums.
I'd wager that the *pressure* in the lines is less than two psi. My goodness. Steel braided lines??? Gotta be kidding.

Yeah, Racer X-8 did a good job of researching everything. He just called me up a couple days after the lines broke and filled me in (I hadn't really thought about it). But yeah I think those telflon lines are going to hold up very well.
One thing Racer X-8 didn't mention... don't lose those copper washer gasket things for the fittings! (we lost one)...

I'm still wondering how difficult it is to pull the OMP all together so I can clean it out and make sure it's going to be working properly. I plan on changing the oil when I'm pulling out my fuel injectors anyways, so it would be a good time to run maintenance on all the systems under the UIM.
I'm also looking for any tips on pull the oil injectors off for a good cleaning. They look pretty straight-forward for removal, but just want to make sure I don't fark something up.

We haven't removed the omp. Didn't even look at how it could be removed. Sorry, hopefully someone else has pulled one and can tell you.
As for the injectors, they just screw-out like big hex. head bolts (19mm wrench, I think).
Plan on finding the lines in need of replacement. Both lines going to the intake manifold injectors broke as soon as the injectors started rotating upon their removal. It was like inevitible, they were just that brittle.

I mentioned this in another post of mine, but never got a straight answer. Is it necessary while your down there doing this to remove the oil injectors and clean those up? or is the oil injector just pretty much a ******* pipe that has no spray pattern and dumps oil in the engine, thus not requiring cleaning?

And here's the opening that the oil comes through:
![](http://img23.exs.cx/img23/5077/IMG_2874.jpg)
There's a decent amount of distance between the end of the injector and the opening, so even if it did spray in a pattern, it would just be an undefined blob by the time it hit the opening.

The injector is sucking at the metered oil on it's intake stroke. There'd have to be some degree of atomization.
The injectors have what looks like a rubber poppet valve inside. Does carb cleaner have any bad effects on rubber? Probably not in the short run.

Ok, I just ordered my tubing and am pulling out the FSM to read up on OMP removal. That site rocks, got a good SPDT relay for $5.87
I'm moving my stereo off the stock wiring and planning on running a line directly from the battery.
Anyways, this should be a great project. Thanks for the all the info you posted.
BTW, I checked the PDF page that has the tubing on it and it's primary use is for air brake lines, and is rated at 150psi. That should handle oil injection with no problem.

Were you on page 4120? I think you were reading the header stuff for "D.O.T. Type “A” Nylon Air Brake Tubing".
Look to the bottom-left section of that page with the heading "Teflon® (FEP & PFA) Flexible Tubing". That's the section that has the #48701031 tubing.
No problem with your order though, as long as you bought the 48701031 tubing.
You should see their printed catalog. It's hardbound with real thin pages and is 8.5 x 11, about 4" thick! I just checked, it has 4,640 pages, not including the 96-page index in the back. It's like a NY city phone book. Their distribution centers must be HUGE! Yet, our orders always arrive next-day here from Atlanta. Amazing, really.

Having said that, and assuming you get one, I found the answer to everything you have asked right in there just now. Chapter 2 Part A section 9. It tells you how to check your oil injector nozzles, check your oil metering pump (output volume), how to remove the metering pump (did you know there are mechanically controlled and also electrically controlled omp's? I didn't

I'm gonna go check MRX Rotary's oil injectors right now... now that I know how. (You should be able to blow thru them by mouth from the air hose connector, but not in the opposite direction.)

One final pic - finished the install & all seems well.
I was concerned about the lack of oil injection during the time it took the omp to finally fill the new lines to get oil to the injectors. We added even more mmo to the gas for a little more lubricity / protection. There was only a little over 1/4 tank of gas - good for that rich mix for a short duration. Turns out, it takes maybe 20 - 30 miles of common driving to fill the new lines.
I had no idea of how to pre-fill them. Then again, I didn't know they wouldn't fill-up at initial crank-up either. I guess that's why they call it a "metering" pump, huh? I suppose a very small squirter, bent at its tip to get to the itty bitty hole in the banjo fitting... ah heck with that. Just let the omp fill your lines & add a stiff dose of mmo to your gas, or what those people do who aren't even using their injectors, if you want, just for that 20 - 30 mile fill-up period.
So, did anybody else do this yet?

Fijenson did it & thought his lines melted
BUT, he found out later that they are just fine

I agree, there is another write up that is just as good. The Mods need to re-title the threads so that it reads more to the point, like "How to fix you OMP lines"
Seems there are quirks to the S4-S5 that pop up over and over. OMP lines, Premix, FPD, TPS, That bolt that goes under the starter being different. Most of the threads are already there but a few need to be added.

Just so you all know, the pressure in your lines is very, very, very low! Unless......the line clogs. The omp is a positive displacement pump, so if a line clogs, it WILL continue to pump until the line fails. But, for all intent and purposes, a soda straw will hold the pressure! ( remember, one end is a vaccum!)
So, any tubing you put on will hold the pressure, probably don't even need to clap it, if it is a tight fit. Just my .02.
I would reccomend transparent line, so you can see the oil, though.

Again, this post needs to be archived as the MOP/OMP comes up all the time. The fact that a nice hand drawing (which I personally have a printed copy in my haynes book) will be very useful to those that are trying to replace the lines for the first time.
