Fuel pressure ?

Fuel pressure ?
I installed a fuel pressure gauge in preparation for shimming the fuel pressure regulator. One thing I noticed immediately was that within 5-10 seconds after the ignition switch being turned off, the fuel pressure had dropped to zero. Is this normal or leak injector or some thing to do with fuel pump?

I think this also has to do with the design of the FPR. I think the stock FPR holds pressure moreso than some aftermarket units. I think it could also be the fuel pump itself.
I would also double check that the connection from the fuel pump outlet to the hardline is 100%, many threads on this. If that has a leak there it would depressurize the system quickly once the pump stops and you'll also have less fuel pressure under load.
