Fuel Pressure issue

I just rebuilt my fuel bowl today with a resealing kit from diesel orings, and for the life of me can't find where my problem is. While the pump is on, my pressure is where it should be right about 65 PSI. As soon as the pump cuts off, my pressure steadily falls all the way down. No leaks on the outside of the bowl, the plunger on the inside seems to work as it should too. Have any of you had this issue before? I don't know what to check.

For my plunger on the inside of the bowl, it seems to have a slight bit of the opening exposed in the closed position, is that normal? Or should it be completely closed off? If so, why would it not be staying all the way up? I'm talking about the plunger in the filter check valve where when the plunger is fully pushed in, the hole is fully open, and when it's not pushed in, it's only 95% of the way closed.

My pressure gauge is on the passenger side port which is measuring after the filter check valve and right before the heads so I feel this is where my issue is, just don't know why

sounds normal to me. The psi will decrease to "0", since the fuel CAN relieve itself, back through the "feed" line. Perfectly normal bud.

Thanks, exactly what bob from dieselorings told me too. He said within 10 sec of the pump shutting off, it should drop to 0 psi. I guess I've just never watched it for extended times before.
