Yep. Need looped lines if you don't do hard lines like above. It is a pita to be sure. To remove I need to pop the lines off before the whole assembely comes out.

Needless to say hard lines is the way to go. Pretty sure these pics were in another thread too.

You will have to find some E85 compatible fuel socks too. Those will gum up after awhile.

I believe all of them are in tank compatible. They also sell a metal filter sock that should be used for a pick up.

You must use lines that explicitly say are Teflon lined or otherwise are alcohol compatible. I royally screwed myself by not. Oops on my part.

Russell Brand steel braided line is advertised as alcohol compatible. I also have read numerous post searching on the subject and haven't found anyone that has had a problem using E85 with the Russell braided line.

Might be an alternative to Teflon braided line?

Thanks, does anyone mind posting some links of the lines? I have found the teflon lined ones, are standard AN hose ends ok to use on E85?

I was looking at the Fragola brand stuff, looks nice, and not too expensive. But do you have to use their hose ends too?

Wanted to add, I just passed emissions with flying colors on an E85/E98 blend.

This is the hose I'm running. http://www.summitracing.com/parts/SUM-220783/

Here are my thoughts/theories on E85 and these hoses. While mine seems to have worked for about a good two years, the thing I didn't think about was how it would act from a storage perspective and having the fuel just sit there.

I've been out of country for nearly 18 months now. I put the thing in storage in Oct '10. Ran it in July '11 for a day, and a few days in Sep. Come last month, it would no longer start. I suspected bad plugs for a while, so when I was back there, I swapped them out and they were some of the hardest plugs I've ever removed. The threads were gummed up like I've never seen. However, it fired right up with the new ones and ran fine, but then started to lose a rotor.

I'm thinking I clogged the hell outta one injector...I hope that's all I did. But I won't know for sure until they're pulled. Being back in the UK now, that's going to be a while.

This is only speculation until I pull those and the lines and see what's going on. And this may only be attributed to the fact it's been sitting. Constant use may prevent these issues, however, over time, I can still see the lines deteriorating to the point of rupture.

That said, get lines that explicitly mention compatability.

The setup in the picture won't even come close to fitting. You do need to loop the lines, you do need to do part of the assembly in the tank as it will not just drop in fully assembled. You'll end up with something that looks like this. It's a PITA to fit, but it does work. The rest of the CJ assembly is top notch.

Also, watch the fuel hose used in the tank. It's hard to find hose that is rated for in tank use with gasoline. The real trick would then be finding something that is in tank rated for use with Ethanol.

I looped mine pretty tight. Worked really well but I still have to attach the sending unit while the assembly is half way in the tank. Was not able to use the stainless fuel socks because they were a little too long. Sending unit also seems to be getting caught on something as the fuel gauge now stops when it gets to about half a tank

Railgun

If you hard line it from the bottom of the plate to the pumps, there's no reason it would not fit. Granted, it may be more difficult to assemble the whole thing, but the only reason to loop the line is if it's NOT a hard line.

C. Ludwig

There is no way to put the bends needed in a hardline to make it fit. Unless CJ has changed the top plate to move the bulkhead fittings.

We were the first to actually make this thing fit with the 044 pumps. The first picture of the setup in this thread with the hardlines was done by someone who actually never installed it. That picture has the pumps setup too far down. It's way too long to ever fit in the FD tank. This makes it easier to bend the hardlines and make them fit. When we bought the setup and tried to install it for a customer, it took CJ and ourselves a couple days to figure it out. CJ had drawn the hanger up in CAD and cut them, but had never actually test fitted them. Perhaps they have moved the bulkhead fittings or changed the hanger to move the pumps since then. With the assembly we had, hardlines were not an option. We tried.

It is WAY too long to fit with those hard lines. Even with the looped lines, it's gonna be a bitch.

Fair enough. I'll shoot them an idea then.

I'm going with Fragola 3000 series braided line. It is safe with all alcohol. 2 parallel -6 lines from the tank to the rails, and a -8 return.

OMG you guys are my Heroes im not very good with fuel systems and i would like to run my stock rx7 on E85. What do i need? can you guys help me? im currently running pfc pink box but i see that its garbage from what everyone says. my rx7 caught on fire last monday and im going to rebuild and i want to upgrade all the fuel system and probably buy a different ecu. do you have any diagrams, part list, and anything else that i would need to run E85 on my 7.

audoetuk

Bc like you said, its not a good daily, but why is that, bc the sucky mpg...would it be good to run this w/ water injection?

iTrader: (2)

No..... you will actually run too much fuel.
Do one or the other.
Yeah, I think I get about 5 MPG.....

I am joining the RX7 FD Crowd but not new to the E85 side. The Vette in my sig was NA Higher compression and daily driven still to this day on E85.

I have found a flaw with E85 though and I wanted to see if those here had started talking about it.

The issue has been brought up on EVO, STI and even Turbo Buick forums.

What is happening is some places are seeing a build up on the tip of the injector of what seems to be black tar. Its not everywhere but I experienced it and it builds up quickly.
From those testing trying to find a cause and why its not everywhere have found out the following:
1) It is actually a clear sticky substance left over with certain E85 solutions found at the pump.
2) Because its not at all stations/locations its speculated to be an additive that's not compatible with E85.
3) Running regular gas through cleans off the build up very quickly one tank will easily do it. Leading to the idea its an additive being added incorrectly by stations.

I have pictures of my Vette's injectors somewhere after only a few tanks it is annoying and it does exist. Drove me nuts.

Now other than that I swear by the stuff it was really nice and I have already bought everything to take the FD to E85 with the new motor.

The idea that it will eat your lines is entertaining. I have done many hands on tests with E85 as well as those here who posted about it. We ran a 1991 Toyota MR2 Turbo on it with NO changes besides bigger injectors. Stock fuel lines, fuel filter everything. No issues after over a year clean as a whistle. There are many other tests like this including just putting fuel line from various cars into containers filled with E85.

I am concerned with the oil mixers being mentioned as having O-Ring problems on E85 I will have to look into this more.

Frankly its not as cheap in terms of 91 vs E85 and gas mileage does go down but the safety and use oil Race gas for such a cheap price makes it very worth it to me.

Also I did not see mention but a general rule of thumb is to take your current injector size and multiply it by 1.47 to get a rough estimate of what you need for E85. Obviously that's just a starting point but helpful none the less when paired with this site:
