What psi do you run your AirDog???

I've got an AirDog 100 on my LB7. I run a needle gauge at the head of the fuel filter. Anyone with this similar setup, what psi do you have your pump set at. Im at around 5 because I was told not to go more than 7 and 5 allows to compensate for fuel back flow. Thanks

7 to 10 psi. If yours is at 5 and not dropping rail pressure at wot leave it alone. The older trucks like around 6 to 8psi. Mine runs around 11 to 12
