 My 750 Holley's hate the constant 7 psi's. They all fail at some point and leak.  I need to invest in a regulator to lower the psi's.  All that gas pumping and build up with no relief.  I do not run a second return fuel line. Never had to with a mechanical fuel pump. I just wonder if it's going to burn out my electrical fuel pump using a regulator. ?  :scratchchin:

I find it hard to believe that an electric fuel pump would even know if you had a regulated bypass or not.
Look forward to learning more about this myself.

That's not fair. Do you run a return line ?

You should run a bypass regulator with a return line imo.   :yesnod:

Yep, I even run one one my mech pump, on an electric pump the bypass system keeps the pump running cooler , bypass systems will also solve fuel boiling, vapor surge, vapor lock, I am down south so we have very high temps.

I do not. Dead head system. Lots of street miles. No issues. Return would be better, i just dont seem to need it in this case.

That or buy a 3/8" fuel line and use it as a return.

I wouldn't use rubber. You can buy a 25' roll of 3/8 zinc coated steel line for around $25 like this one. Just bend it as you install.
