Hey guys, 2004 f350 with an airdog II 165 and a regulated return. I started the truck and instead of the normal fuel pressure of 62 psi, it is now at 18 psi. The pump does seem a bit louder. I replaced both fuel filters and the water separator and there is no gelling, I use an additive every fill up. Any ideas? How can i determine if it is the pump itself or maybe the gauge got screwed up? The regulator return gauge still reads its regular pressure and doesn't jump around, if that matters. Thanks. -Steve

Same problem I had along with many others, IMO ditch the AD 2 and have them replace the unit with a 100 or 150 and re install the stock pump.

Usually lack of pressure and a loud pump means its sucking air somewhere. Check all hoses and fittings.

i felt around all the fittings and tried pushing them in again but they were all tight already. pump sound did not change, all seems good there. only 4000 miles on the pump btw.
