Here's a curly one. I obtained a sportomatic oil pump with the intention of converting it to pump transaxle oil. The pump that came to me is missing the donut in the guts which makes it pump. The four pointed star is there but the 5 pointed donut is missing.
Pic shows a housing with the donut installed.
Attachment 501680
I believe the part number for this is 905 107 901 00
Any help/leads appreciated.
