Another one of life's mysteries. Why is the hex on the temp sender 18mm? This is a rarely used metric size, I only had one because I had a special need for a stubby 18 for some work on the 928. In the larger sizes 17 and 19mm are the standouts, 13 and 14 in the smaller sizes. 11/16 AF is a poor fit, so I got out the calipers and saw 17.90mm.
The old sender was REALLY tightly done up, and when I got it out the ally sealing washer was shagged. The supplied fibre washer was too thin - the cone on the sender hit the manifold well before the washer, so I had to scramble for a thicker fibre washer, none of my copper or alloy washers would fit.
