Default Normal 24V Bosch VP 44 Cummins fuel pressure

After running around the internet and seeing all the weird tales of fuel pressure... I desided to make a quick video of what my truck does with...

AirDog 150
Edge Comp (5x5)
Stock Injectors

Conditions Fire up... Get out to the highway and row out the gears up to 75 MPH. Fuel pressure gauge is in the center 15 PSI is straight up and the first tick mark you see to the right is 17.5 PSI.


I idle at 17.5 PSI and WOT at 15.0 PSI @ 75 MPH.

This is a fail!

Wow, dropping all the way to zero, on WOT.
I have the same gauge, but mounted mine down by the center console, below the ashtray, to the left of the stick, above the acelerator pedal, almost out of my sight. Lol. When I WOT im to busy looking at the rough road. But I will make it a point to look. When I have dead throttle, I look and the pressure is at 17-18.
I like the pillar tri gauge set up.

This is why I always ask for both fuel pressures (idle and WOT).

RV275 finely gave up on me I was having a serious miss when hot only at idle. I didn't want to take chances since it wasn't getting better.

So the stockers went back... (cry... Sniff... Sob...)
