    PTFE and FEP Heat shrink tubing are both compatible with Ethanol if someone really wants to go there. There is this huge overreaction to the use of E85 in modern fuel systems. While more corrosive than gasoline, it takes a very long time to see any noticeable side effects of running mixes of it unless you have something submerged in it that is directly susceptible to being attacked by its corrosive properties. Which obviously your butt connectors were as they got soft in a short period of time. That style butt connectors are the cheapest of the cheap, I would throw them away before I wired anything with them

    I hope it looks good when we do it. I might just have to peek in there today.

    What do you think about using a paper clip in place of the plastic clip, on the vent hose from the top of the LPFP? Mine broke and I wrapped a paper clip around it.

    Honestly not the best solution, but it will probably last forever. Not like the ethanol is going to eat like its acid or something.

    Ok thanks. I don't know too much about metal properties etc. When I run e85 we are talking 1-2 gallons to clear timing corrections on pump maps.

    Someone should really put together a 455lph install kit including the "hard to get" hose. If anyone does, I'll gladly be first on your list of orders.

    That's totally different install, this is for the inline 255.

    Thanks man! This is the kind of stuff that I like to read about someone else screwing up/etc so I don't ever have to deal with it. I assure you my sphincter was at full pucker when I saw the connections all jacked up. Crisis averted!

    I couldn't agree with you more. Truth be told when I looked at them I didn't like them but I was hell bent on doing the install right then and assumed they must have been special E85 compatible connectors, you know, 'cause they were part of the E85 pump kit. I looked for others locally but no dice. Lesson learned.

    Just wanted to clarify something on this thread as I've been asked about it a couple times.

    You're blaming that failure on ethanol....in reality...had you been running 100% ethanol...you probably wouldn't have had that issue. The fact that you appear to be using cheap plastic (ABS) connectors (supplied to you for this purpose so understandable) without heat shrink was more likely the cause.

    Case in point....

    bottom line people. Whatever fuels you are running, use quality parts when upgrading. People going cheap is the cause of most of their issues.

    Exactly what SteveAz said the lack of heat shrink is what happened ask me how I know? I believe the bundi connectors are made out of ABS and they do well in there so ABS should be good to go. When I went to dyno my RBs I got into a little bit of a rush and forgot the heat-shrink my connections looked exactly like that.

    Really like that site. So I guess, the polyolefin or the polypropyplene heatshrink wraps i used are A grade when used with ethanol but a C grade when used with unleaded gasoline.

    Gotta take a look at my pump asap..

    Remember...it's not so much that you are trying to seal the connection as fuel is not conductive. A quality, properly done nylon crimp connector would be fine without heat shrink. Proper heat shrink is just another layer of protection that would have saved the OP a headache.

    When I do installs they look like this....

    Click here to enlarge

    They are not sealed...but they are staggered and my kits include PTFE tubing. so while I'm sure plenty of people have opened them up and seen this crinkly and what looks to be cheap heat shrink Click here to enlarge...it's not...it's actually fairly expensive.

    Sounds about right. Good stuff SteveAZ. I'm not 100% sure what the connectors supplied to me were made of, but I am sure it was the wrong stuff for the application. Good point on it being incompatible with gasoline vs ethanol.

    Regarding heat shrink tubing -it's my understanding that while it may seal for you, it's not intended to be used in a submerged application for the purposes of sealing. I.e. obviously another layer of protection, but not mandatory.

    Exactly, it's more for safety and short prevention, as well as a fire lol. But yea the heat shrink wrap is not a good sealer, just to keep the connections from touching each other like they did in yours when they bonded.

    Upon further inspection, the gelling of the plastic -whatever it is- surrounded the connectors and provided a protective layer to blobbed up plastic, insulating the tank from the spark. So the connectors both almost killed me and saved me. lol
