Mechanical Fuel Pump vs Electric Fuel Pump...???
I've been having vapor lock issues and want to get it FIXED. After looking my situation over, here's what I have.....350/300hp GM Performance Crate Engine; Holley Street Avenger 640 (with heat shield on the manifold) and Holley mechanical pump with 1 inlet and 1 outlet (no return line...the return line is in-tact but plugged), Auto Transmission and 3.08 Rear End. OK...I have since purchased an ACDelco Mechanical Fuel Pump 41240...it has the correct # of inlet/outlets. Before installing it and re-hooking the return line, my mechanic (who has been working on my Vette for as long as I have had it..12yrs) told me.."If I were you, I would install an electric fuel pump with regulator." Either way, he's going to reconnect the return line.
Now my questions....Should I change from mechanical to electric fuel pump with regulator to 6.5lbs? If so, which model/brand would you recommend? AND Why?

The electric pump is only an upgrade if you need it, you don't.

Thanks Guys...I'll have him install the AC Delco mechanical fuel pump. It seems ANYTIME I replace any part with an aftermarket or an enhancement, "Ellen" (name of my Vette) seems to NOT LIKE it and it fails. ie: QuadraJet to Holley Throttle Body Fuel Injection...FAIL Replaced with Holley Street Avenger..and She LOVES IT! 140 amp alternator...FAIL 100 amp alternator...loves it. I can name several other parts that I replaced and it failed and when I installed the OEM or equivalent, it works FINE. Oh well....
