LB For the dumb non-mechanic they use some oatmeal to soak up the extra fluid that is leaking out. Or they can go to NAPA for a ring/seal kit. With the kit in the hand ask a friend for the all American tool kit ( aka 5/8, 9/16, 1/2 and a 7/16 wrench ). Take a couple of holding bolts off and the hoses too. Take the pump apart so that you make exchange old stuff for the new NAPA stuff. Rodger & Gabby
