    I grabbed a set of billet oil pump gears and they don’t fit. Does anyone know the outside diameter of the gears that fit 4v housings? I measured 89mm on the billet ones and 83mm on the stock ones. I know the difference is supposed to be the width. Does anyone know what the larger diameter gears work with?

    Call the manufacturer of your gears. I just received a 4v pump with Boundary billet gears in the mail the other day. I'll see what the paperwork says. I know for sure it has the clearances. I can't (won't) open the pump to measure the gears tho as it will void the warranty tho - sorry.

    I have my old 2004 Marauder pump and can easily measure it for you if you are sure it's the same as the one in your motor.......Marauder was 4.6 4V!!
