fuel lines

Ok here's a dumb question, how many fuel lines should there be on a CJ7? supply, and return, any vapor lines or anything? And where can I buy new fuel lines? Should I bend my own or what?

Re: fuel lines

Well, you didn't say what year jeep you have... for a point of reference, my 83 CJ7 has, supply, return and a vapor line.

I would probably just buy it bulk and bend it myself (which I'll be doing shortly as part of my motor swap.)

Re: fuel lines

Bending your own is a lot cheaper, you can get a 20' stainless steel roll for about $60. The preformed pieces (ss) are Really $$$.

Re: fuel lines

You can get 20 or 25 foot of anodized Aluminum for $25 and Stainless steel for $30 from Summit. My Jeep only has one fuel going to the engine. The previous owner ripped the rest of them off.

Re: fuel lines

All of the above are right....but for the few extra bucks, go with stainless...and buy the tube bender. Once you have it, you will be surprised at how often you use it

Re: fuel lines

Question,any of you guys ever see heavy black plastic replacement fuel line? i saw a Commando while back that had it,it was solid
enough to put a rubber hose over and use a hose clamp on but was flexable enough to follow the frame pretty well.The Jeep was in a
junk yard a long time and the plastic line still looked good,and you could see it had been on it a long time and gas didnt seem to have
affected it at all,or could this have been for some other pourpose originally?

Re: fuel lines

A common name for that stuff is "Polly Flow". Its used a lot for running air lines and the vapor return. However, it has two problems...first, you have to use fairly large tubing to get the proper amount of gas flow...and second, because its so flexible, it does not stay in place without a lot of frame clamps....with metal tubing, you bend it...it stays that way.
