Is it recommended to change out the fuel PRV (pressure reducing valve) after installing a fuel pump. I ask because I notice an appx 2psi gain when I installed the new Bosche OEM fuel pump. I installed a new pump after the engine quit and I noticed the pressure at 15 psi. The next am it started and pressure was again at 30psi but I wasn't taking any chances so I replaced it. Now, I wonder if I miss diagnosed it and the fuel PRV may have been the culprit. Change out or re adjust it? Experienced advice is greatly appreciated. Thx in advance!
