Starting and idling problems

Hard starting, idles eventually but after a little throttle runs like crap again.
(Fuel pressure gauge mounted on the column)
With Fuel pressure, if I turn the key and let the pump prime the gauge shoots to 50psi. I monitored it over the space of 10mins with a camera and it dropped down to 35 psi. Dropping at the rate of around 1-2 psi per minute. Is that acceptable bleed off for this style of filter regulator? I noticed some systems say it should hold pressure for half an hour then others don't hold pressure once turned off.
