Thread: Beer keg gas tank

Tweet

if you were worried you could make a small sump in it at the bottom think it would have to go less than a 1/8 of a tank to get no fuel

make sure you mount it good use plates backers so it will not rip out make sure you vent it out of the trunk space .put a fire wall up behind the back seat 0.030 will work steel or aluminun not not use a vented cap vent must be out side fo the trunk space .may have a hard time getting it fill in the trunk there is laws on this ? make sure to air it out good after fill up

I am planing on using the original filler neck ,just fabing a new pipe to fit

hotroddaddy, there will be no problem using a keg in the trunk. Just make sure to vent the keg to the outside of the car (fumes in the trunk area are a disaster waiting to happen, especially if you mount your battery back there too).

The reason you would want the return line in at the top instead of halfway down the keg is that 1/2 way down, there is a "head" of pressure from the fuel in the keg that is opposing the entry of the fuel in the return line. There should be no resistance to the flow of the return line.

Anyone mounting a keg should be very cautious about the supply line coming off the bottom of the keg. Make certain that there is no way the line can be torn from the keg by flying debris or by suspension parts moving to their extremes.

Some cells are sold with foam that is stuffed into the cell to prevent fuel from sloshing back and forth in the turns. I think I would investigate a source of this foam to stuff in my keg.

Speedway sells it for the sprint cars.

Thanks Jim.

Most aftermarket gas tanks today have a sealing gas cap, and the fuel outlet in the top with a pickup tube going down to the bottom. They also have a check ball in the vent tube to prevent all the fuel from draining out the vent if the car goes topside down.

This is a DOT requirement on all new cars. I'm not sure if it's required on street rods, but it's very possible your state inspection could reject a car with a bottom-feed gas outlet. Even if the state doesn't require it, it's another safety idea that should be considered.
