Fuel regulator question

[Mrbill426]

Trying not to clutter up my engine compartment with extra components... when using an Edelbrock 1407 750cfm and a stock replacement mechanical fuel pump is it really necessary to install a pressure regulator?

If you stock pump puts out less than 7psi to the carb then no.

Thanks!  I have one of those vac/pressure testers I will put on it.

7psi or less is what you are looking for.
