Fuel System... lines, pump
 

Getting my fuel system in place with a stainless fuel line kit from inline tube.. I got a kit from them with the main fuel line, return line, and vapor line. I am debating over whether to toss the return line and get a fuel pump that takes just the main fuel line or to include the return line on the truck and get a 2 port fuel pump... Is there an advantage in having a return fuel line?? I ask because I've been having trouble with fitment of these fuel lines on the frame and one less line would save some aggravation.

Also, is there a certain procedure/any tips for installing brake and fuel lines? Everything is run on the passenger side and it's pretty tight with 1 brake line and multiple fuel lines... pictures would help if anyone has some! (the truck has a single tank on the passenger side)

Old thread but does anyone have input to this? Thanks

It was there, and you have it, so use it.

I believe the return line allows the fuel to recirculate so it doesn't heat up and cause vapor lock.

Ok yeah I read that somewhere. For some reason my truck originally came with 2 lines: the main fuel line and the vapor line to the emissions canister. I am curious why it did not come with a return line from factory? It used to be an inline 6 though and now it will have a 350.

Strange. My '83 has the return, but it is a 305.

my 78 Jimmy has two ,no return(or charcoal can either)
the 79 does,and it's to help with the vapour lock...
my 79 Jimmy tank would be different style ....
