Fuel pressure issues
Alright guys its been awhile since ive been on here my son was born 5 months ago so ive been pretty busy! I was having concerns about my fuel pressure so i took a few readings:
Idle: 15psi
Regular acceleration: 20psi
Hard acceleration:20psi
WFO: 23psi
Cruising at 70mph: 20psi
So I did the bb mod and just got readings:
idle: 20psi
Regular acceleration: 80psi
Hard acceleration: 80psi
WFO: 80psi
Cruising at 70mph: 80psi
now when I let off the throttle at 60+mph it maxes the gauge out at 100psi and hangs there until i am back on the throttle or my speed drops below 50-55. I cleaned the screen and its a new fuel filter. Any insight or comments or advice would be appreviated!

When you remove the FPR for cleaning, make sure you don't drop the o-rings into the engine valley.
I didn't realize mine had fallen out. I had a huge fuel "leak" at the FPR. Fuel accumulated so deep, I had to use my angled pick and go "fishing" for the missing o-ring in the "pond" of fuel. After 20 minutes of scraping the valley, I landed the o-ring and all was well. I now keep "spare" o-rings in the garage/toolbox/break-down box, just in case.
