1975 CJ6 fuel line question....

On my 6 (258 I6) when I got it, it had a gas can set in the back!!! The fuel line to the fuel tank had steel to the forward of the rear spring hanger, then poly to the tank. So many things were changed on it, I can't begin to figure out how it's suppose to be. Can I run steel line from the motor mount back to the fuel tank in one piece???? Thanks,

 

That's what I did on my '74. I bought 5/16" steel brake line at Autozone along with some rubber fuel hose to clamp over the steel at the ends so it was flexible to the tank, and to the fuel pump. I also did my return line the same, except with 1/4". It's worked beautifully so far.

 

Many thanks, I didn't know if there was some (pies-r-square) reason for the poly.

 

The only poly that was on mine was at the rollover valve, and that just gets plugged into some rubber line that runs to the evap canister.

 

I used the same materials and did mine the same way.

 

Just replace all line on the jeep 5/16" work just fine and my 360 is running fine....like other said i have a same piece of rubber hoze between tank and fuel line.

 

my 74 came with green nylon tubing from the tank to the frame mounted steel line right in front of the P/R shock mount. Steel line forward to the P/F shock mount. I dont know what was original from there.
The vapor line from the liquid check valve forward to the canister was red nylon line. All still intact and pliable. I replaced it all. Steel line where original and new black nylon fuel line where nylon was original.
