As I mentioned above, there was a seller on ebay selling a NOS made in the 60's flange with a similar picture of yours and the same part number and logo on it. I reached out to him to measure it. He came back with a measurement of 12.2mm. Couple that with me getting the same measurements from two of my original flanges on my engines, and the mystery continues in my mind. _________________ Contact me at [email protected]

Another one...
So far, these seem to be in 3 thickness ranges - 12.2ish, 12.7ish, 13.2ish.

Interesting thread. There is at least one other size. The aftermarket spacer that I removed recently was 13.81 mm. This spacer was about 30 years old and had the VW/Audi logo, the same as the new CIP1 spacer pic that I posted earlier. It had not been machined.
As far as these height differences being significant I think there are some variables. When I removed my old pump, a 30 year old “cheapie”, the pushrod protrusion measurement was only 10.55 mm - 2.45 mm under the recommended 13 mm. That was with a worn pushrod - 107.4 mm. Car ran OK but generally did not get a lot of high speed highway use anymore. My theory is that this “cheapie pump “ was putting out a higher pressure, as many of them did, and this compensated for the thicker spacer.
The optimal VW spec of 13mm of pushrod protrusion assumed a fuel pump that was putting out the proper pressure. That was a given “back in the day” but not so much anymore. _________________ 1960 beetle

I'd measure the spacer height on my two VWs, but I'd have to dig through my records as one has the original factory spacer, one has a replacement. But since the 1835cc engine is now in the 1971 and the 1600cc now in the 1970, can't remember if the replacement was done before I swapped engines.
I know the 1971 was the VW where I broke the stand; I was (foolishly) trying to quell an oil seepage issue, thought it might be from under the stand. _________________ 1970 VW (owned since 1972) and 1971 VW Convertible (owned since 1976), second owner of each. The '71 now has the 1835 engine, swapped from the '70. Second owner of each. 1988 Mazda B2200 truck, 1998 Frontier, 2014 Yukon, 2004 Frontier King Cab.
