ok guys just got my ad hooked up and running, adjusted the regulator as stated by the directions, and my fuel pressure gauge is telling me i only have 3 lbs???????? i bled the line going from the ad to the vp, the pressure gauge going from the vp fitting to the gauge, no air, is my gauge bad, or my Ad bad, or something else?

 

What do you mean adjusted it per directions? It should had come set at 20psi. Have u every tried to turn it in (more pressure) when the pump is running to see if it climbs?

 

i turned the truck on and it said only 3 psi, so i shut it off climbed under and adjusted it like the directions say to as if you dont have a pressure gauge.

 

Mechanical gauge with an isolator? And blead as in solid fuel goin to the vp?

 

mechanical with isolator yes and yes good solid stream of fuel to the vp, my buddy actually got a nice diesel shower!!! haha

 

I hate mech gauges... Mine in my 03 is junk. Did it work b4 the ad or is this being added at the same time?

 

it worked before, i had a junk bd diesel lift pump that had about 11 at idle and 7 at wot. so i figured why not put the ad on so i can get an edge or quad, but now i have to take it to the local shop only problem is the guy just had a baby so i have to wait. oh well.

 

How much fuel is in the tank and I doubt a trip to the shop is needed.

 

only about 40 miles into a full tank so there is alot of fuel in there, and im starting to get very impatient which is a good sign its time to let him take a look at it. plus my tank guage isnt working and im tired of messing with everything

 

That woulda been time to fix the sending unit when the fuel module was out. Turn the key on bump the starter so the pump fires up and crank in the adjustable regulator and see if the pressure rises. I still think the gauge is the culprit
