Review on Enhance Your Chevy's Performance with the PureFlow AirDog A6SABC409 Lift Pump DF-165-4G (2001-2010) - An In-Depth Review by Ronnie Saylor

I installed the booster pump according to the instructions - there are no problems. I started the car, checked the tightness of the pipes - everything is normal (no leaks). I looked at the pump and saw that it was dripping from the pump body (and not the water fittings). I contacted Air Dog tech support, they suspected the o-ring was stuck where the pump connects to the base. He told me to take it apart and make sure the o-ring isn't pinched. When I opened it up I found that the block did NOT contain any o-rings - someone had forgotten to install them. I put in the o-ring from the service kit that came with the unit and reinstalled it on the truck - that fixed the leak problem. Would give 5 stars if I didn't have to spend 2 hours disassembling/restoring/replacing a unit that should be up and running!
