Type 1 oil pump revisit, For the last time Options

Finally put the short block back together this past weekend! (IMG:style_emoticons/default/beerchug.gif)
This is for the next guy who wants to put an o-ringed oil pump into their motor.
I purchased one from low budget VW and it had the correct circumference, but sat too deep into the type 4 case. It bottomed out against the cam, and the o-ring groove was inside the case instead of the case bore ( Pic 1,2). So I dropped the idea of the o-ring pump and just ordered a CB performance pump built for the type 4 engine. I once again measured the circumference against the case and it was good. But, after looking at it closely in the case I noticed that the oil intake once again didn’t line up properly, and it only had a pubic hair’s worth of metal riding on the case. It was sure to suck air, even though it was the correct circumference (Pic 3).
So I ended up going to the local water jet shop and took one of the oil pump gaskets with me for the shape. They cut out a spacer from 1/8 inch aluminum and it worked perfectly. Now the intake port lines up correctly and the o-ring sits inside the case bore as it should (Pic 4).
Forgot to take a picture of the spacer, but it looks like this one from the German Supply kit.….(Pic5)

No the CB performance one is not an o-ringed pump. It fits well in every respect via circumference and depth with the camshaft, but the oil inlet and exit do not. They sit too far back into the case and barely are sealed due to it having such a small sealing surface.
The o-ring pump I used was from Low Budget VW, and it was the 30mm pump. If you use a 1/8 inch spacer, it fits like a glove. But it has to be installed while the case is split apart. Due to the O-ring will be destroyed if you tap it into the case already assembled.
