Too Easy...You da man!
Well done mate, love a good result!
In regards to the tap...Wow, that's crazy, usually even with a washer they leak, it should be pouring out!
Naaaa I'm just stiring, couldnt resist. Lols
There are no Dim Questions mate, just Dimwits! Ask any question,and ye shall receive! Lols
The tap simply has a tapered thread, (1/4 BSPT from memory) and does not require a washer.
I would still use thread tape or a thread sealer if you are restoring it.
You can't pull the tap out when its on the cowl,so you need to undo all your good work if it leaks. Also some paint doesn't like fuel.
