After spending over a month cleaning my tank, I decided to remove the drain plug that was seized.
Good news is I managed to remove the brass drain plug... However:
Any suggestions

Re: Fuel Tank
Find a decent old school welder, cut the old boss off and weld on a new one. I know that is over simplifying the job but I think that's your best bet.

Re: Fuel Tank
Find an old school welder brave enough to weld a petrol tank.
Filling it with water to eliminate petrol vapour from exploding.
Alternatively get a new one made from stainless steel. It should then be safe from ethanol based petrol.

Re: Fuel Tank
Since you have a pattern you could try Stotfold Engineers.

That's bad luck Steve. Am pleased to hear there is a drain plug. I am not sure mine has ever been drained since new!

Re: Fuel Tank
Not sure it would have been welded due to the dissimilar metals and thickness, brazing would probably be the best option

Re: Fuel Tank
It did cross my mind that considering the number of times most tank drains are used, the easiest solution would be to cut off the remains of the boss and just weld or braze a plate over the hole.

Re: Fuel Tank
In the case of the SP Nick you are quite right in my view.
About the only good use a drain plug is in a fuel tank is to drain it for some reason, perhaps by chance diesel should manage to get into the tank, but with an SP that is not possible other than getting the tank out. If you have the tank out you may as well use the neck to empty the contents.
Not sure about welding or brazing a plate over though.

Re: Fuel Tank
When I did my tank I left the drain plug well alone, because I thought I may end up with the same problem as you. What about grinding it flat and using petrol resistant adhesive to fasten a plate to it and then line your tank with one of the kits you get online. My tank had been repaired several times and I used one of the lining kits and up to now it as been brilliant
