I know! They all told me i was dumb for wanting to put it on my cummins. Of course they didnt know i dont have one, so i told them, and they still told me to buy some insane fass or airdog system for millions, when i dont need that kind of pressure and volume. I have a gauge. So if it goes bad i will know. And to have two on hand, perfect. I have one with 160k on it and another with 80k on it. Both for 40 bucks. Now i just need to figure out how to wire it up polarity wise. It shouldnt matter should it? I want to just hook it to my existing L/P harness already down there. Are those wires enough to supply this pump with juice? I really dont even know what the cummins L/P looks like lol. He is also sending me some fittings for it. I think they are banjos?
