Engine/Transmission (1998.5 - 2002) Fuel pressure too high?

[WJohns]

After 3 factory lift pumps & 1 VP44 I decided to go with an aftermarket pump system. I chose the AIRDOG setup. The fuel pressure with the factory Carter pumps was always around 12psi to 13psi at idle & when I stepped on the throttle I could pull it down to 5 or 6psi. With the AIRDOG my pressure is 17 to 18psi at idle & even under load it dosen't go below 16psi. Can there be too much pressure & will it damage the VP44? Thanks for any input.

17-18 psi is not too much for your VP44. The AirDog won't damage the pump from too much pressure.

15 psi is considered the perfect pressure but I've been running 20 with my FASS HPFP with no problem.

I got a customer running the glacier diesel pump and it runs 20 at idle and the lowest we have got it was 5 at wot with the smarty on 8 and power puck.
