My Edelbrock Pro-Flo 4 Install

My bad when I stated earlier that the sump requires a return line. I saw this in the instructions and thought it was a return line but looks like it’s just a vent? I never really considered the sump system, so didn’t spend a lot of time studying it.

True, you wouldn't want gas spilling out in the engine compartment in the event of overflow! The vent-line at the tank is soft and it shouldn't flow fuel, so it should be easy to put in a T-fitting.

Any chance you remember the Cal ID number for your 351 application? My ECU is buried under dash with sticker side not visible or accessible. Now that I’m ready to start/tune in screwed appearantly.
