hey guys quick question about my fuel pump, i bought a new 80 GPH fuel pump and installed it a while ago. and i plugged of the fuel return line because it wasnt on the new pump. now is this bad at all and is it hurting my gas milage at all. thanks

 

A mechanical pump? What PSI does the pump put out? If there is no return line on a mechanical pump, well it doesnt need one then.

 

well i understand if it aint on the pump then the pump dont need it lol what im saying is there a certain thing in the tank or by any chance it needs the return line... also to your other question i have no idea as i have it regulated to 5.5 psi

 

If it's not FI and doesn't have some exotic/wierd/overkill pump you don't need the return line. Was your car originally a TBI car by chance?

 

Thats what I was implying. THere is nothing about the car that requires it, so if the pump doesnt have it, cap it off.

 

If your not using an EFI pump then you shouldn't need the return line. With my setup, for example, I chose to use the stock EFI pump with a return-regulator which still does need the return line...or else i'd have like 80psi up my carbs ***!
