fuel return line ????

[ocbaud]

my old stock fuel pump had an inlet, outlet, and a return line. do aftermarket pumps like say the holley 110gph pump have a return line? if not, what do i do with it?

no, aftermarket pumps don't have it. remove it and plug it back at the tank. and make sure you have a vented gas cap.

gas cap that goes behind teh gas door?

what can i plug it with at the tank?

I used a rubber line and a bolt in it with a hose clamp to tighten it down to prevent leaks. You can get a vented gas cap at the auto stores. I got locking matching set. Cost me $20 from O'Rilley's. I had to order them but was there the same day.

i already have locking gas caps, how do i know if they are vented?

[low 84]

just take it off and turn it over and there will be some weird looking stuff on the back side of the cap. thats the only way i can think of to say it. if its not vented than it will just look like solid plastic. i plugged mine the same way brandon did

oh, well it has a little black thing that moves around and stuff. so i guess they are vented

[mike reeh]

im not sure what the big deal is about having a vented cap if you remove the fuel return line

but if you have a charcoal canister, then you neednt worry about venting

its supposed to prevent vapor lock or something. i would/did eliminate the charcole canister also

I removed my canisters as well. No need for them anymore since I'm emissions exempt due to age of the truck

I just left mine open. No biggie.
