Funnily enough it is at the very bottom part of the tank, right where water will collect when it separates from the petrol,

good point, i've just checked and unfortunately it is clean and dry under the tank and round the petcock. The tank is really bad with flaky rubbery stuff in it. The only good thing is the paint job.
I have another tank that is clean on the inside but has been hand painted (brush) by a previous person.
Question, Can you pressure test a tank if so how would you seal the fuel filler?

Have never attempted to pressure-test a motorcycle fuel tank, but with the tank removed, would guess by closing the cap and removing the petcock, and introducing water from a household tap through a hose fitted snugly into the petcock hole (perhaps using a rubber grommet to help seal the where the hose enters the petcock hole), water could be seen escaping from inside the tank through a leak source.NZGlenn wrote: ...Question, Can you pressure test a tank if so how would you seal the fuel filler?
This method would not harm the tank's exterior paint finish.

If you get the tank rigged for a pressure test, keep the pressure LOW. 2 or 3 psi will be enough to find a leak with soapy water on the outside.
The flaky rubber stuff is probably a sealing compound that was used to stop the leak, maybe by a previous owner? It has failed. I see you have another tank. You just need a paint job.

He hasn't had to re-do any of them, some were done quite a few years ago. The Ethanol crap doesn't seem to bother it, unlike some of the Tank Lines on the market. Of course proper application, cleaning etc is key to any of them.
Of course a good used tank is always best, if it isn't rusted also.
