Part number on the four existing pumps are 8M3137
the parts book says the part number should be 4H5238 17a1 and up
the 4 seals 2m8663 shown in the parts book appear to be the correct ones.
the other 4 seals 2a3307 look too fat--I have one spare 4h5238 pump and the sealing surface for the 2a3307 is sloping like the inside of a funnel. the existing pumps 8m3137 sealing surface are flat and the seals have a bigger ID. The old seal are hard to read all I can get
is 2M44??. These two different # pumps appear to be the same and both work. Can someone tell me what part # I need to order the seals (😎 for pumps 8M3137? Thanks Lex

The 2A3307's are correct the old seals get cone shaped from age. Like this old timer.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
