Oil pumps VW, where can I find an overview?

Hello,

"Does anyone have good knowledge of oil pumps and can tell me which pump is compatible with a Jetta TD (JR engine)?" The original VW part number is: "068 115 105 AN".
What about the fuel pumps from T3 1.6TD engines, will they fit?
Isn't the only difference always just the intake manifold, and can't that be replaced?
Does my smart book about golf cars state that the 16V engine uses the oil pump from the diesel engine? Is that correct?


Regards,

Hendrik.
