Stock fuel pump has a vent line. Edelbrock don’t.

Hey Guys, Chrisnofix here.

I changed the quadrajet out for an Edelbrock and changed to an Edelbrock fuel pump. The stock fuel pump had 3 lines one being a vent line I believe from or to the tank? And the Edelbrock fuel pump has just the 2. What do I do with the vent line ?

There's a fuel inlet, a fuel outlet, and a return line. The small line, I think 5/16's, is the return. Just cap it off so it doesn't get dirty, in case you need it later down the road. Then leave it alone.

if you want to keep your return functionality, which i recommend, you can install this

vertically installed off the pump-to-carburetor, then the small nippple would feed into the return

^^^60s to early 70s Pontiac/Chevrolet big block fuel filter. Expensive now and getting tough to find. I found a mutch cheaper much newer alternate fuel filter. Not the Wix 34040 or 041 can't remember off the top of my head will try to remember to look for the box on Wednesday.
