That's not a frequent problem. We've sold hundreds of AirDogs. We've been selling them since they were first release, when they were called the Fuel Preporator. We've only had 2 customers call us since then with the motors going bad. If I remember correctly the manufacturer replaced the motor on both free of charge. Back then they had somethining like a 7 year warranty. Now all of their pumps have a lifetime warranty. Either way you should be covered. Give them a call and see what they say. If the pump is going bad, and not the motor, then I'd be interested in knowing why if I were AirDog. Could be that it's not getting enough fuel to keep it cool, causing it to burn up. All of their 150GPH and higher units require 1/2" fuel lines to get them enough fuel otherwise they can work too hard. I'm wondering if that is part of your problem. Is your fuel line kinked somewhere or have a bend in it where it's getting constructed? Take a look. Good luck.

 

Time for a sump and some 1/2" or 5/8" line feeding the pump!

Good to see you guys here dieselmanor! Are you thinking of becoming a sponsor?

 

Thanks for the help
First I changed the filters at 30K
I opened them they are clean
The. New set had same pressure
I have installed factory settings
Using fuel bowl and left stock filter in cap
Did not touts the factory reg

 

What's the regulator set at on the AD2? Is it the factory spring, or do you have the blue spring up in the fuel bowl?

 

***Side track for just a second***

Are these tanks metal or plastic? I am looking in to a low profile bulkhead fitting (yes there is such a thing) to gravity feed my pump instead of sucking it out of the tank.

Thx

 

Karl, that's what the billet sumps are for dude...

I think I've seen plastic and steel... might depend on bed/cab config and year the truck.


Ooooh purdy...

 

$150 for a sump on a flat tank (but thats another rant), or $20 for an AN bulkhead fitting? Not too hard to do the math there. BTW, if my tank is so low that I would run the risk of uncovering the fitting, I should have filled up BEFORE I got to that point, huh.

Guess it's magnet time.

 

The motor is gone
i checked the gyro pieces
they are fine
the motor got real hot ...on both ..pumps
Blew the fuse ...instantly...like a dead short...
i am using the reg in the pump ...factory setting...

Do i need to take out the ford spring in the front!!!!

Where is it located

What presuure should i run

The air dog was running 55 psi on my gauge pod

 

I have read about ADII systems and completely bypassing the OEM regulator and filter on the motor. It makes sense because the AD system has its own pump and regulator. Basically, you plumb directly to the banjo fittings.

However, given that it instantly popped the fuse (and I am FAR from an electrician) I would look over the wiring for chaffing or something else abnormal.

 

okay about plumbing straight in
where is the regulator??
How do i remove it?
if decide to bypas everthing and go direct to banjo bolts
What do i do with the return line to the air dog 2 pump
Or better still where does the return line come from (the Bowl) ??

thanks
Jim
