Got a fuel tap on last night on the non exhaust side. Exhaust side is a little more complex as I am angling the tap down away from it. It was actually a bit of a headscratcher designing the tap interface as I am using the small ktm style bolt on taps instead of taps supported by a threaded fitting. So as they fuel hole in the tap is sealed by a o ring but not the bolt holes you cannot drill the bolt holes all the way through or fuel will leak out of them. I settled on using a block of alloy 13mm deep that i could drill and tap but not all the way through. This way i can weld the whole block on and drill through without the issue of the fuel moving between the block and the tanks skin and coming up from the bolt holes. Glad I got my head around this before I made anything!
