Re: Rear tank conversion - need new pump?
Any stock type pump dead heads when line psi reaches set point. Determined by internal spring pressure.
The bypass regulator just helps circle cooler fuel to the carb. Personally I like Carter pumps, and I never had issues with them.
The regulator is not nessacary, but helps of you have heat soak issues. They become nessacary I'd you use a bigger Holley mechanical pump since they typically run at 8 psi vs a Carter or stock 5-6 psi.
Even your average parts store pump will work fine for a stock engine, and if your thinking LS leave out the regulator.
