Aeromotive Regulator I have an aeromotive boost referenced regulator and when I prime the pump it goes to 58 psi then falls quickly.......car runs fine and have no problems with dual pumps, but am trying to find out why I cant maintain pressure after being primed.....Is it the regulator, or one of the fuel pumps......or do I need a check valve.....?

Dual intank walbro 255's........they are supposed to have check valves in them.....if I put a check valve in it will be up by the fuel rail after the regulator.......
I am going to put the stock regulator back in, just to see if it holds pressure......if it does, I need a check valve......if not, I need new pumps

You do not need a check valve.....
You likely have an internal leak in the tank. Everyone blames the pump check valve & I've never had one with a problem, but the lines in the tank are normally at fault.... especially if you used a piece of rubber line.
The regulator can still bleed down & no check valve will cure it because it is not backflowing, it is bleeding off through the return line in the normal direction of flow. Most external regulators will do this & it is normal.
