electric fuel pump return line?

I have a 1980 Transam that had a pontiac 350 with a mechanical fuel pump. I pulled that motor and im putting in a stroked sbc. In the process i decided id rather run an electric fuel pump. I bought a holley red pump off ebay with no instructions and i was wondering if i have to run a return line? I was under the impression no, but i want to make sure. This pump does not require a regulator. Any help is greatly appreciated.

You might want to go to the Hooley site and look up info on the pump you have for pressures and specs and instructions.

I have run a holley RED with no return line and had no issues. I now have a BLUE and no return. I have not had any issues and have been told that this can be done on a BLUE with no issues.
Again, I had no return on a RED for many years with no issues.

if u want a return line, I'v seen people put T's in the fuel line and run the return back into the main feed line b4 the pump with a check valve so it don't go up the return, dosn't really return but does it's job by recirculating out of the main fuel system, with discharged preassure.
