AirDog fuel pump was purchased on 6/13/12. I didn't install until early 2013. I thought I had a pump motor problem and received a new motor from PureFlow on 4/24/13 (I have all receipts). Turned out to be the O-ring. I bought and installed a Fuel Pressure gauge to verify. I am now going a different route now. I have a 2 pump motors, new Baldwin filter. The Water seperator is still in good shape. I'm asking $500 + shipping. Thanks.
