Bad AirDog

[CPH]

Installed my new AirDog about 4 weeks ago. Comming back from Atlanta yesterday fuel pressure started to drop (yes I have a mechanical fuel guage.) from 27lbs to 10lbs over a period of 4 hrs. Pulled into hotel befor the DC beltway. Called AirDog. They are over nighting a new pump only @ 86 bucks. I also have to pay for another night at the hotel. They are not giving any leeway. Not happy. At least I can fix it. A ball fell out when I pulled the pump off the assembly. I was on my back and can't see the top. Any body know where the ball goes?:{

The ball is spring loaded and controls the amount of pressure in the pump. It lets excess fuel flow back through the pump on the airdog 2. On the first gen airdog the extra fuel flows back into the tank and the ball should be in the return valve. Hopefully the spring is still there. I believe you have the setup in the bottom picture and the ball goes where the regulator is labeled.

Which Air Dog do you have? Can you specify a little more where the ball came from? It may have been something as simple as the ball not seated properly in the return line. On mine the spring stretched (it was also a few years old) and the ball stuck in the spring and allowed the pressure to drop. I wound the spring up a little tighter and put it back together and it seemed to hold pressure but I ended up ordering a new spring anyway.

Just curious, did you mail back the warranty card when you installed the pump? Those folks are usually great about standing behind their warranty.
