fuel return ?

Hi guys, I have just removed an old efi flapper system from my V8 and fitted a Edelbrock manifold and Holley 390 carb from Real Steel. The problem I have is that on the old EFI system I had a fuel return hose but on the Holley carb there isnt one .......or am I just overlooking something?

Many thanks Holley

nope carbs generally dont use a return, just block it off.

Thanks for the quick replies

this is a most helpful place. I purchased an electric fuel pump from RS at the time I bought the other bits and thats rated at 7 psi, is this too much for the Holley 390 ? do I need to drop the pressure ? obviously these guys know their business but I have done a bit of searching on here and some people are saying between 4 and 5 psi, will my 7 psi just damage the floats or flood the carb ??

Many thanks for your help
