Default Need help on fuel pressure

I just put a new walbro in 2nd one already from livernois and my fuel pressure is at 58 then back to 50. the car bucks like crazy.i have a fuel pressure gauge on it and when i shut the car off it drops to 0psi in 1min.the factory always stayed at 55psi for months in storage and i had a small leak last summer but its not leaking now.im so lost on this and need direction if i should bring the car back.

Sounds like you will need to go back in the tank and check for cracked or loose line that is allowing fuel to leak which will kill pressure.
