Should tbi fpr bleed off pressure after prime 1994 rcsb 5.7

[man-a-fre]

Have a rv morse fuel pressure gauge fitting on my tbi and it reads 12lbs at prime koeo then bleeds off to 0 pretty instant when prime shuts off.Truck runs fine holds 12lbs running pressure starts fine no ill effects just wondering if there is a seat or somthing worn in the fpr or if this is normal.I have another 1994 rcsb 5.7 that does the same thing.The injectors don't drip and the pattern looks fine the fpr doesnt drip or appear to leak either.

Nope it's normal. The Vortec FPR holds pressure after you shut the pump off but, the TBI bleeds off instantly after the pump stops priming.

Thank you so much! I was really hoping for that answer.
