Sorry! I mislead the list on the article to Moss. My buddy has written an
article on keeping wire wheels cleaner by using a O ring. More later... Now
back to the water pump. The washer should be 1/8" X 3/4" or 7/8" and
should be at least a grade 5, grade 8 being preferred. And always check it
for tightness.
