Thanks for replying college man.
This is not a washer. The pump spits apart and is sealed with copper gasket. The dealer may have a reseal kit. It used to cost $35.00 Now it might be even more expensive it they still have them. This is 20 year old vehicle.
The sad thing is that the seal did not leak, but I had to take the pump apart in order to replace a leaking oil seal that cost me only 6 dollars.
Regards,
Sam
