I has issue with fuel pressure that I had been seen normal it would be about 20 psi but now it had dropped to 12 to 15 psi even changes fuel filter and adjust te regulation. It don't help..Should I contact the air dog company and see what to do? Or time to upgrade to airdog 100 with two filters??

The AD II came with the compete wiring harness including fuse and relay. I can see what it is tomorrow while its daylight. All I had to do was install it. It has been on the truck 2 1/2 to 3 years. No issues with it so far.

You sure are having better luck than I am with it then! Thx, FT

I am glad I fought mine back when I did. It seems the problems started with ownership change.

Well.... I have one of the older units and once the first one puked, the replacements seem to last only a year and change then burn up. Would totally agree about the new company. I called them when the first pump puked and they were not only not helpful, but bordering on abusive with their comments. If I had the choice of having to deal with their sales rep I talked with or riding a bike, the bike would get the nod. He was a jerk... Only after reading online that if you had an old pump that Pure Flow would handle the warranty did I contact them. They have been wonderful to deal with on the replacements... just wish that we could find a pump that would last.
