Re: Putting a drain plug in a gas tank?
N2 might be ok. I have used a goo to seal the tank.
Here is what not to do: I bought a 54 Merc that had a gas leak. Turned out the former owner has stuffed a bath towel in over the tank to reduce rattling. I dropped the tank and flushed it in the street in front of his gas station. 3 times the left the tank in the so
un over lunch (Lemon Butter with my aunt.) Then he dropped a match in the tank. The tank did a dance and we soldered coffee can sheets and good to go.
Never use a vacuum in a gas tank if the gas
can has liquid gas in it. fumes and motor spart5s=boom
