Fuel Pump question
I'm installing a ZZ383 crate engine into my 72 Chev Custom Deluxe and noticed the high output Holley fuel pump has only an inlet & outlet while my original has a third. What do I do with the third and what's it for? Thanks!

Re: Fuel Pump question
The third was for a return line to your tank. Your truck might not of had a return line originally. Was the third one capped or plugged off?

Re: Fuel Pump question
The third line was connected to the stock fuel pump. I thought only fuel injected had return lines but I'm a rookie.

Re: Fuel Pump question
If you're using the new holley pump you should cap off the line back to your tank.
