My gauge is bouncing all the time(16-12 #'s back and forth) driving me nuts. Never did this before was thinking filter might be needing replacement. So where are you guys getting your spin ons from A.D or have you found a cheaper source. Thanks, Nate

I was wondering the same thing. Mine isn't bouncing the pressure, but I was wanting to get some spare filters so when I need to change it I have it.

Fleetguard ff5617 is cheaper than the Airdog replacement filters and has the same specs.
Fleetguard Filter Store online has them cheapest I could find anywhere.

Duster75, my AD150 did the exact same thing for quite a while. Finally got around to tearing it apart and found the the rubber ball that regulates the pressure was actually stuck in the spring therefore not allowing the ball and spring assembly to seat properly and hold constant pressure. Called AD and they sent me a new ball and spring set free of charge. Stretched the spring out a little to give me a hair more pressure and all has been good for a couple of years now. The ball/spring are located in the larger of the two side by side ports located on the filter housing. I think it takes a 15/16 or a 7/8 wrench to remove it.
