Aeromotive makes decent stuff. That pump makes around 15 psi or so. If everything from the tank forward is sorted out I would possibly look at a 13220 Aeromotive regulator if your sure you have a pressure problem and it’s the regulator.

The old cheap Holley regulator will work just fine....but I recommend you use the bypass style......if you deadhead the fuel system it will regulate when running but will eventually climb to max pump pressure when engine is off and key is on.
