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
