Something to consider when planning or applying a fuel system of mix and match components. Mismatched components and dirty fuel systems cause a great percentage of the problems folks have to work on. All fuel systems are dirty whether with lines cuttings or old line deterioration. Taking the time and caution for filtering the fuel put into the tank through something so simple as a coffee filter is a natural solution.....cheap and effective.
Fuel systems should be evaluated as a
SYSTEM where all the components must work together and that basic thought will get you very close to a best performance package!
The "old tried and true" (sic) Holley regulators will not hold more than about 21-22psi line pressure and at even less than that they have significant pressure creep problems. They also have the greatest "droop" curve when tested. Those things were designed to operate with a 10-12psi system pressure back in the day.The only saving grace is that they are cheap....
A reminder: What you need is
flow at pressure where the system pressure before the regulator is opposing the gravity of the vehicle's acceleration. That is if the fuel is in the rear of the vehicle and the carburetor is in the front. It is not the expense of the components that qualify them, but their
actual functions that make the best selections.
