Hey,

So with the key in and engine off I'm getting about 30-31psi.

Then with the engine idling in park I'm getting about 30-31psi.

Then when I put the truck into drive it stays around 30psi with a little fluctuation.



I checked my fuel pressure a long while ago and I think it was around 35 to 40psi. I'm going to try changing the fuel filter to see if the pressure changes, but I'm pretty sure the fuel filter is at most 2 years old.

Anyone know what an acceptable psi is for the engine to be at in drive?

All data shows KOEO 35-45psi and KOER 30-40psi. But something weird is going on to have the fuel pressure hover around 30psi.

Thanks
