Well i just installed a holley red fuel pump and aeromotive regulator i got it the best i could but the damn fuel pressure is jumping. i have a holley mechanical fuel gauge in the reg and it will only read 3. WTF the pump should do 7 psi. any ideas and i need them ASAP

 

You need an adjustable pressure regulator. I use a Barry Grant regulator.

 

its adjustable aeromotive, i think it is working just not sure, it flatens out after sitting and after a drive and check it it says 5.5 psi, i dont konw im just going to drive it and see what happens, its running better then ever KNOCK ON WOOD so i dont know what to think
