A friend of mine is in the market for a lift pump, i have a spare air dog still kicking around that i took off my truck after it was totaled. The truck i bought came with one so it just ended up on the shelf to sit for 2 years with diesel still in it and in the filters. Thought i drained it all out but after moving it some spilled out. Anyways im wondering if its more useful as a paper weight more than its intended purpose. Thoughts?
