Afternoon, I currently took on a Honda accord project car, the problem I’m having is my VMS Racing fuel pressure regulator gauge drops to zero upon shut off. I have tried several tests and came up empty. Car holds at 32 PSI while idling but it takes a few seconds to start up.I pitch the air hose connected to the fuel pressure regulator and no change in gauge occurred, I detach the air hose and waited for fuel to shoot out but nothing. Fuel pump replaced and works just fine, car does not store or shut off, everything seems to be working while driving but fuel pressure does not hold when car is shut off. It is simply a ghost issue. Anyone have any suggestions or solutions to this issue.

 

You might need to add a check valve before the FPR, to keep fuel in the line. What you're experiencing is common, if the check valve in the pump is kaput (or if it even came with one).

 

@The Toecutter Thank you for your Response, do you have any suggestions?

 

From what I understand McMaster Carr sells them, as does Summit Racing and Jeg's.
