A note on the video in the previous post:
- At the very beginning, the gauge is already at around 5 psi, most likely due to the priming of the accelerator pump. It was at zero when recording was begun but the parts during which the truck was not running were cut out to save time.
- The fuel pressure is seen dropping slightly as the engine is heard revving at the 3:38, 3:52 and 4:12 marks.
If I remember correctly, the fuel pressure should be 5 psi. Is that right? If so, how should I lower it from 7 psi?
