Appreciate your responses and opinions.
To be fair, there's no problem with my M20's fuel tank.
I am now dealing with my BMW R51/3 and looking for a solution for it. Its fuel tank will probably be disqualified.
The truth is that these days the gas tank is undergoing patching repairs, and a pressure check will reveal whether we have succeeded or not.
And if we do not succeed, then I would like to be ready with an opinion whether to purchase a replica, and where.
By the way the advantage in the tanks of our M20's is that you can dilute any fuel refill with one liter of diesel. I have been doing this for years, the motorcycle works very nicely and I believe that maybe the diesel helps a bit in preventing the rust on the sides of the tank.
Who knows.
