Before you buy you might want to look at two other alternatives. The first is the tried and proven accusump system that you can get from Canton, Moroso or Peterson Fluid Systems and the other is this really nice remote filter with a built in pressure pump you can spin with an electric drill or a speed handle. It is also made by Peterson Fluid Systems, click here =>
Remote w/Primer.
This is what the gizmo looks like
Of course you could also just put in some Pro-Long and not worry about these sorts of things.
