The learning curve has continued.
There is now a full set of brass thumbscrews holding the boot liner in place and some of them are fairly similar to each other;

and there is a new 0-ring oil seal arrangement in the tank filler cap

To be honest, while the oil seal may well stop the seapage that always seems to happen unless the cap is done up seriously tight with a fairly fresh Viton gasket and PTFE tape on the threads it might not for a couple of reasons; the filler on the tank is out of round and the filler cap is drilled off centre for the dip stick. The next version might not have the aluminium plug with the o-rings threaded on to the dip stick to allow it to float slightly so that it can self centre but might have to make it slightly longer to make sure it aligns reasonably.
Things have now come to a halt for the moment as I'm away offshore again this afternoon. Might be a good thing since I now have a home made oil seal, I need to do my bit to get more oil out of the ground!
