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
