Keep in mind they are billet alum new dyno'd units. Nothing is used or reman. I am finding out you get what you pay for with these carsTear the pump open and stop the speculating. The pump would have to be run almost dry or a big air pocket to get a vane to break/ crack. I would like to know what these other companies are doing to them so they can charge $300 for a rebuilt unit? Besides add -AN fittings.
