So I had an idea on this new fuel tank. Weld in a bung for a tank vent/roll over protection valve on this stock 66’ fuel tank. Fuel puking can be a real issue. So I bought this steel pipe bushing at a hardware store. It must be steel to weld to a steel tank. Please be advised this was a brand new tank and not a used tank that had fuel in it. Please never weld on a fuel tank that held fuel. The old thought of welding a tank full of water is not safe. Let a used tank sit and dry for a while after washing in hot water and soap before you try to weld on a used tank. Gasoline fumes are EXPLOSIVE!
Then I screwed in a 1/4” brass pipe fitting. It can be anything (in this case 1/4” npt or “national pipe thread) because that was the inside thread of the pipe bushing. Brass will not stick to the threads but will protect them. Once cool it screws right out.
Before I drilled with a Unibit. Trust me these work really well on thin sheet steel. I presrilled where I wanted with a 3/32” bit to keep the unibit from walking while trying to start the hole.
After fitting wire brushed off the coating with a rotary wire. I welded the two parts (tank and fitting)
After welding I pressure tested at about 2psi and soapy water. All good.
I was so pleased with the results I added a drain bung to the bottom of the tank to drain off fuel before winter rest. Before using it, vacuum the tank out with a shop vac and even wash it out to get all the metal chips out before putting the tank into action. Even give a touch up of paint.
