Default Issue? After FPR install...

Never checked to see if system held pressure before replacing the FPR, but I do know that the car started right up before.
Since new FPR the system will go up to max pressure and then quickly drop, and so I've noticed that its harder to start the car.
Where to look for things that may have gone wrong?
I read in another thread about people being fine with the pressure not holding, but it seems that it did before, so maybe its a problem in my case?

A stock FPR hold pressure after the car is shut off, an aftermarket does not. that is the only major difference. Sounds like it needs a rebuild.
