    Iím glad I spent the $25 on the install tool. I donít think it ever would have come off with the screwdriver and hammer method. I needed a two foot breaker bar in my vice to break it loose.

    Going thru some good DIY reading , I wanted to mention something or more like ask . All I see is a Oring between the pump and the block . How is it possible to leak fuel into your oil ? What other seal breaks ? I remembered reading a post on IG a while back , someone had installed a autotech piston with the correct tool and somehow fuel and oil mixed . Causing him to drain out his fluids , change plugs and eventually but a new pump .
