Basically I found an air dog on Craigslist for really cheap. The listing says its for a 24 valve truck it has new filters but no wiring harness or lines

I already have 1/2 inch feed lines and a draw strawII. The question I have is. My trucks a 12 valve. Is there a difference between the air dog pumps for 12 valve and 24 valve trucks?????

 

24v pumps do not put out the kind of pressures that p-pumps are designed to operate at. Some of the electric pumps can be regulated up, but some do not have a big enough motor to supply the flow and pressure. For what you have done to your truck, this would be an absolute waste of time and money. Stock 12v lift pump will out supply what you require. Depending on the model of Airdog, it may not even outflow the factory pump.

 

Tate is right do not waste your money that air dog is a piece of Edit

 

Why replace the long lived, reliable mechanical pump for a failure prone electric one?
