leaking self levelling pump? reseal parts available

i have seen a few problems with the leaking self leveling pumps, here on the board, and at the shop. and with a new pump over $1000.00 117-230-00-64
it pays to try to fix the original one,

you can buy the seals gasket an o-ring seperate, i suggest you buy 2 of the radial seal (004-997-01-47) they can be tricky to install.

gasket 114-236-00-80
seal 004-997-01-47
o-ring 010-997-43-45
