We are doing the v6 to v8 swap and the V8 is carbed. The V6 had an electronic fuel pump in the tank that I took out. I extended the pick up tube on the sender so that it is now in the same location as it was when the electronic fuel pump was there. Ok enough background I hope.

Here's the question. I can purchase a mechanical fuel pump that has either one or two lines going to the tank. Which one should I get and why. I am hoping that I only need to use one line. The pickup line from the tank as the others are disconected right now.

Thanks.

 

doesn't matter man, if it has two lines to the tank, one is a return line. My car's factory pump had the inlet, the outlet, and the return line, i plugged the return line when i bought a holley fuel pump that only had the inlet and outlet, no problems yet, that was almost two years ago.

 

Thanks for the info. Is there no problem with venting the gas tank so that the fuel will flow.?

 

vented gas cap...
