How safe Is it to weld a petrol tank? I've had a tank sitting empty for a few months and noticed a couple of pin prick holes that need welding.
I don't mind welding it but I've heard a few horror stories of tanks going bang even when cleaned, filled with water or exhaust fumes ran through them.
This tank has been empty and no cap for a few months, so how long can petrol fumes hide in the metal pores/tank joins?
