Stihl MS260 fuel leak

[Jim372xp]

I'm still waiting for a few bits to turn up for my mates ms260 so as its in bits i thought I'd clean the fuel tank on it ,but when cleaning it with meths and tipped it forward i noticed meths leaking from the rear av mount screw hole ,is this normal or is there a crack in the front half of the fuel tank or does the av mount act as a seal when all is assembled:confused1:

There is no seal through it, it simply should not be leaking. Seems like you got a crack or something on the tank...
