1972 GMC Power Steering Pump bolt leak - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a leak from one of the lower pump mounting bolts. There appears to be a white plastic like washer/seal between the hex nut and the pump body. I plan to replace it with a new seal and flat washer to push the seal. Anyone have an idea what material seal I should use? see photo of pump backside. Thanks for any help

The seal (rubber) is between the tank and pump on the inside. Looks like someone is just trying to patch it up.

OK - I am not sure what seals I need and where they go. Where can I get an exploded view with parts list? thanks for your halp

There's also the Edelmann 7910. I'm sure any rebuild kit will be fine

I'm think I used thin copper washers to seal those spots years ago
