could I take a new air tank, cut the fitting out of it, and weld a gas filler on , and use the drain fitting for the fuel line fitting? this would be for my ratrod project and would most likely be mounted on the frame rails
Matt - Why not use a 30 (or 40) pound propane tank. The Clifton Park transfer station gets the 30 pounders regularly - there was one Friday and a couple last week when I was there. My spare 20 (almost new) came from there - and they have many that size but not always the latest version with the triangular handle.
Once you empty it, remove the valve and the top and bottom flanges, you have a nice beginning to weld brackets, fillers, bungs for pickups and a roll over vent.

I always fill gas tanks with water when I am going to fix one, sometimes it needs a hose fitting to keep the water level just below where I am welding. A used gas tank should be double washed with hot soapy water a couple of times first. the speedway catalog says the gas cap and filler are aluminum but the last one I got has the steel liller neck so I drilled and tapped the old beer keg .
Darn.... why didn't someone call me? I should have thought of that.
Thanks for the great ideas.
I notice the spun aluminum tanks offered by Speedway are not recommended for street use. Too thin or non-compliant. Though, I don't know what regs covering (pun?) gas tanks. I'm thinking none since you see so many jacked up trucks around here with their tanks hanging there waiting to get pierced in a rear-end accident.
Maybe someday I'll confess what I was planning for a gas tank. Mine will be (note; future tense) sitting out in the open on the rear crossmember. That makes me a little nervous as I think of it as a target.
I knew a guy that was into demolition derby and mud trucks. He saw a couple of old style propane tanks in my shop recycle trailer and said they use them for fuel tanks. tougher than fi a mini car or truck tank.
If you come out of the bottom of the tank with your supply line, either roll the tank a bit so the fitting isn't directly on the bottom, or drill the stop out of a compression fitting body so you can slide the tube thru enough to keep the inlet slightly above the bottom of the tank. Otherwise, any and all trash or condensation goes straight into your fuel line.
I used a air tank on a trike i helped build. I also have used kegs, spun alum. tanks all have pros and cons. big thing is make sure its clean and empty.
One downside of these type tanks is no baffles so fuel will slosh around. I had one that caused the engine to stall under hard breaking or when stopping at the bottom of a hill.
Just a heads up.
