The remains of the plastic plug measure up to M20, but 14tpi. Found a 1/2" BSPF is closest, found one in my box of fittings and it fits.:)
But I've ordered a couple of real ones from Ebay. The real ones seal on the face, my temp plug seals on the threads.
Here are some pics of "The Banana".
First, the pack.
"The Banana" on the left. 300tdi soft-dash auto.
The Rover towing it. 4BD1T with Isuzu 5 speed.
"New Brian" (family guy reference) on the right, 3.9 V8 with EAS.
