Not sure if this has been done but I haven't seen it nor did I search so flame away if I'm wrong and if it has been done then it should be archived or somthing! So both FC's I own have a rear hatch with out a wiper but still have the button and the tank in the the rear. Since I never used my rear wiper on the FB and knew I would never want to on my FC I knew the tank and button would be useless. After premixing both my FC's for a while I had the idea to convert the tank and pump into an oil injection system into the gas tank. I told a friend about it and today he decided to try it since he had some free time. Just using some extra tubing and a 90° barb.

1. Pull the washer line out and usually it comes with a 90° barb on the end. If not scrounge around for one.



2. Pull the cover plate on the passenger side of the car in the rear so you can see the filler neck hose.


3. Route your line somewhere out of the way and over to the cover.

4. You can either drill a hole in the cover and run the line through the cover or drill a hole else where in the rear and run it under the car over to the area of the filler neck. You can use a grommet or a larger hose to keep the metal from cutting through the oil line.



5. Take an awl or screw driver or pick w/e you want and poke a small hole in the thicker area on top side of the filler neck.



6. Now put a little bit of Right Stuff! or w/e your fav fuel resistant sealer is and apply some to the barb and carefully push the barb into the filler neck where you made your hole. Note: be sure not to apply to much or you could have some sealant floating in your tank. You can see where this is in the 2nd picture above.

7. (Usually I fill my tank up when it gets to a specific lvl on the fuel gauge). So measure the avg amount of premix you use when you get gas into a cup and then poor that into your tank and mark XX ounces with a line on the side of the reservoir and repeat until it is full.



8. Take a measuring cup and put your line from the washer reservoir that you just filled up with oil and hold your button on the dash down and count in seconds until it fills up with w/e amount of ounces you use on avg when you get gas. Do this a few times so you can make sure it's somewhat accurate. For ours it was 10 seconds I believe.

9. Hook your line from the reservoir to the barb you installed into the fuel filler neck.



10. Now go to the gas station, hold your rear sprayer button and count xx seconds. Then get out and fill her up.

Hopefully this will be helpful for some people. It makes it a lot easier/cleaner than having to pull a funnel, measuring cup, and premix jug out every time to fill up.

bump i know i was the one to try it out but rolf came up with it he deserves the credit and 10 seconds equals 8 ounces of oil for us.

 

this is brilliant. pressing the rear washer does not cycle the rear wiper correct?

 

solareon I'm not sure since none of My FC's have wipers lol the hatch glass is swapped.

 

I like this idea, I may give it a try... although the looks I get with the funnel and quart of oil are priceless.

 

What happens when the little barb falls out of the filler?
What happens when you overfill and the gas spills all over the ground?
You know the fill is double lined right?
There's also no inline filter either so anything that gets in is getting into the tank as well.
What happens if the pump dies adn you just count away and nothing get's in?

Don't get me wrong, I like the idea, but there are too many things to go wrong.

 

I completely agree with Brian; there are too many things that would unexpectedly destroy your engine. If people are looking for a two stroke oil alternative, take a look at his setup.

 

I like the idea, but I would be likely to go get an aftermarket fuel level sender the cheap kind for a motorcycle – the skinny self contained tube style - and a fuel level gauge to mount up front. If you mark the tank like in the picture than you could look to see where the needle on the gauge lies for X amount of oil dispersed.. looks like the container is good for 2 full tanks assuming a 100:1 mixture. So ¼ mark on the gauge should have enough oil (8oz) to supply half a talk of gas. Not 100% accurate but close enough for government work - as they say.

 

why not just tap a barb directly into the tank where the fuel pump is? then put an inline filter on that line.

 

im sorry, but i've never heard of anyone using two stroke mix in their gas before.

is their a link that states the benefits so that i can educate myself?

 

This is not your ordinary car,please do some research..

 

My filler is not double lined. when i made the hole i felt around and there was nothing else in there, as far as falling out you can put some right stuff on it or zip ty it. As far as filtering it when you measure out your premix how many people clean there funnel and measuring instrument every time they fill up? With oil flowing through the pump i would think it would help lubricate it and make it last longer since its not flowing and amonia based product, also how many people have had the washer fluid pump go out on there car? ..... if you dont want to do it don't, just an easy simple mod that makes it easier in my opinion

 

Seems like a pretty good idea IMHO. It seems like there is a filter in the reservoir also to keep the spray nozzle clean. I’m not positive but I have seen them in other cars.

I wouldn’t feel comfortable doing it unless I checked the tank every time I filled up. I’m sure it could be rigged up good enough to feel confident that the hose wouldn’t fall out.

I have been thinking of premixing, is there any way to tell if the stock lubricator is working properly, or is the only way to tell is the seal go out? lol

 

Yes it is unless tampered with. Just becuase you couldn't feel/see it through a 1/4" hole doesn't mean it's not there

Right, becuase that's a good way to keep a plastic barb stuffed into a rubber hose in place. There is no good way to keep that barb in place or **** out of the tank becuase it doesn't belong there. Bad idea to put the barb there.

I'm talking about schmeg getting into the tank, the washer tank or the gas tank.

If I'm not mistaken 2-stroke is going to be a little thicker than washer fluid, regardless, you're missing the point.

Are you saying the washerfluid pump is indestructable? What if there's a short, what if the switch dies? Youi're measuring a critical internal engine lubricate blindly. There's no way around this unless you're taking the cover off each time to make sure nothings is spilling out, looking at the tank before you start and after you finish to "measure" it out. There's too much to go wrong.

I have no intentions of ever doing this. I have my OMP injecting synthetic 2-stroke. I also measure out an put in about .25oz/gal in the tank. Here's something for people to do that will probably take less time over the course of a year than doing this mod -
I have 7 little 8 oz bottles neatly stored in my car with a measured out 4 oz in each of them. When I get gas, I open the storage bin, take out a bottle, each with a number on them, 1-7, open a cap, pour it in, fill up, done. No funnel needed, no measuring at the tank needed. The bottles last about 1500 miles.... funny, that's about what an oil change lasts. I fill the bottles everytime I change my oil and I NEVER worry about it. Nothing to go wrong as I have pointed out with your mod. Like I said, I like the idea, I think the excecution can be dramatically improved upon.

 

I think the idea is decent, but also agree that that the first time you get lazy and don't double check things will be the time 2-stroke didn't make its way into the gas tank. I say rewire the pump with a toggle switch to activate it near the reservoir. Then you at least have to stand and physically monitor how much 2-stroke you are pumping. I still prefer the premixing method using a modified S4 MOP with it's own 2-storke reservoir though...

 

Im not so sure overflowing fuel will be that much of a issue because it will flow up the hose then probably just drain back down again.

its not a TERRIBLE idea, just needs some more thinking, I would test some of that hose to see how much it can withstand fuel, vapors are worse then liquid so you would not want the hose falling apart on you.

Small bottles are the key, not only are they pre-measured but you can fill them from a more economical gallon at home, a funnel in the trunk makes a mess, even in a bag.

I also use the small dentist cups, they are 3oz if im not mistaken and you can squeeze them so they fit right in the neck, then just toss it out.

This is when I dont keep the 2 stroke reservoir under the hood filled with oil.

 

I'm using it on my S6 OMP. They are available for all models iirc. MUCH better way to do it in my eyes. Keeps the vaiable nature of it which is needed. When you're sitting at idle, you don't need 128:1 mixture.

Idemitsu rec's 256:1 FWIW and the stock OMP injects about 4-500:1 iirc.


I'm with Rob though, measure it out so you're sure. I like my little red 8oz protien drink bottles. Everything measured out before hand, mo mess, no funnel, an extra qt with measuring cup in the same bag for the resevoir under the hood and incase I'm going to a track event or the dyno and I want to give it a little extra love.

Eliminate all possible sources of failure and it's a decent idea.

 

The barb falls out? If I remember correctly N/A engines have been using this similar method with vac lines only reversed how many times do you have a vac line "fall off" Right Stuff is more than sufficient to seal off any leaks around the barb even tho I highly doubt it would have any.


Over filling your tank.....usually when the pump handle releases that is a good indication that your pretty much full. I don't think I have ever done such a thing...guess that is the diff between me and you.

double lined? what does that have to do with anything?

Inline filter....most tanks have screen in them and unless your running a filter and bag less fuel system I wouldn't worry since there is more of a chance that premixing with your funnel and measuring cup will have dirt in it.

Pump dies....are you def? I can hear my pump back there and I have full interior. If I suspect an issue then I could pull my jug and premix normally.



I never said anyone HAD to do this. I was putting this out there for people who are tired of measuring every time they fill up. This can be improved upon in w/e way anyone wants. The point was if you have everything back there why not use it for something. Honestly this doesn't take much time at all. I have thought of running the line for the oil into the top of the pump/pick up.

 

why not run a line from that tank for example, to the pull of the fuel pump, but put enough resistance in the line where the fuel pump mixes it for you as it pulls gas?
though that would probably be easier if not for intank fuel pump..

true, but remember, vacuum line has vacuum
this barb will have pressure when running, though not enough to make much difference

 

I just buy my premix in 6.4 oz bottles and throw them in my golve compartment. Single use and no open bottles to spill oil. You fill up and throw in a bottle and then disgard the empty bottle.

I still do not understand why people find this hard to do.

 

There's your answer right there. A vac line will pull itself onto a nipple/barb. A pressure line will try to push itself off.

Really? Have you tested this "rightstuff?" Have you contacted the manufacturer to find out it ethanol tolerances? Have you submersed it in fuel to see how long it takes to disolve? I've seen 20y.o. fiberglass fuel tank's eaten away from the inside. I've seen epoxy lined fuel tanks disolve and clog fuel filters/ruin pumps/blow engine. I've seen sand sucked into a fuel sock becuase the plastic fuel cell started disolving. I've watched cured silcone melt becuase of gas..... shall I continue?


No, one of the differences between you and I is that I have enough sense to think ahead about all the things that can go wrong and adjust accordingly. You on the otherhand seem to think that some hardware store marketing bullshit is the answer to solving a potential fuel leak...FUEL LEAK. You punched a hole in the fuel filler

If you have to ask.......... there is an inner liner in that tube. The acordian piece doen't carry the fuel.

Not mine.

I thought the whole point of this is so that you DON"T have to carry a jug.

And you're giving advice that could potentially destroy someones engine/cause a major fire hazard. I'm pointing out these facts.

Drilling and tapping into the top of the fuel pump cartride would be a better idea, a MUCH better idea.

 

gets to be expensive, have you priced out a gallon container?

 

Seems like an interesting idea to me, but to each his own. I just premix the old manual way..

 

I know that is why I posted it..........The way it was done is purely experimental...i mean unlike you not all of us were born knowing everything..we learn.
