Last July I installed a new VP, new overflow valve, ISSPRO mechanical fuel pressure gauge with a snubber, aftermarket filter mount with a
Cat 1R-0749 fuel filter, sump kit and a Raptor 150. I have maybe 20-30 hours on this system. Had several problems in the beginning, but they more or less stabilized, unfortunately by setting my pressure at 11psi. Low, but being that the truck is near stock, and the pressure held even on heavy acceleration, I dealt with it. Yesterday, I dug the truck out of the snow bank since we had a good 3 days of 30+ degree weather. After a spell on the charger to recuperate from Alaska winter, fired up just fine, albeit the pump took its sweet time to get up to pressure. (Pump runs on key power, no starter bump required). After she spent the night in the warm shop so I could inspect the rear end, I fired her up, and pulled her outside to play with the pressure adjuster. It took over 1 full turn to go from 11 psi to 13 psi. Didn't seem right to me. Driving around the block, it held decent pressure, but the ups and downs I did see seemed rather sluggish. Can anybody offer me any insight? Plan on calling outflow soon as I am able. Thank you.
