Hey guys, I gots me an AirDog II 165. I installed it back in September and have been with this quirk since then. I'm not sure if it is a problem or anything but just wanted to see if others experience this?I got my fuel pressure at 20psi according to my fuel pressure gauge. When I start the truck and the grid heaters kick on, the fuel gauge will go down to 15-16psi. When the grid heaters switch off, the fuel jumps back up to 20 psi. I have watched the fuel in the line move back and forth to the gauge as they switch on and off.Its a mechanical gauge with a cage protector in between the stock fuel filter housing and gauge.WOT never shows fuel pressure to be lower than 15psi on the gauge.
