I have the Holley HP 150 billet gerotor pump and really like it. one year and going and not so much as a burp.
never will i buy a mallery gerotor again. went thru 2 in one year. cheaper built than the holley billet. poor tolerance settings on the gerotor to. weaker motor.
have had several holley blues, they were good but the vanes get out of tolerance quickly and wear. sometimes would quit working and could tap the pump and it would work again.
