b6 oil pump

[Dragonhealer]

Only difference between early and late (big nose crank) oil pumps is late pump housing. Will mount a crank angle sensor and has an upgraded bypass plunger.

The only difference I know of between all b series oil pumps is if it's a small nose or big nose. So it should fit a bunch of different models.

90 is definitely short nosed. Sounds like their year information is skewed.

91-93 is probably for a small nose crank. The other is probably for a big nose.

It's weird, I went and looked up the 90 oil pump and it had a different number.
