I've been partially using some stock Chevy fuel lines for the TBI conversion in my Cruiser.

After a little forced down time, I fired it up and found that the fittings into the back of the TBI unit are leaking fuel <IMG SRC="smilies/frown.gif" border="0"> Enough to be a fire hazard... or to clean the manifold depending upon how you look at it <IMG SRC="smilies/biggrin.gif" border="0">

After pulling the fittigs off, I found the nylon "washers" were destroyed. No comment on what is left of the hard fuel line going in <IMG SRC="smilies/clown.gif" border="0">

Has anyone used other fittings with any sucess? Or is my best bet to replace the nylon "washers" and the hard fuel lines with stock fittings/lines?

Thanks in advance for any help/advice someone will surely provide <IMG SRC="smilies/tongue.gif" border="0">

I found some tbi bodies at the junkyard that uses the standard brake or fuel line type fitting. Most were the one barrel type that had them.

I swapped a 350TBI in my CJ7 and used the same lines you mention.

I did have the Howell TBI kit on the old 258 that was in the jeep before. It is the same TBI unit thats on my 350 except with smaller injectors. The Howell kit came with something very similar to the picture below. From there you just ran hi pressure rubber hose and attached them with hose clamps. Never a problem.
