Ok I know I will get flamed hard for asking this as I am a firm believer in safety first on all cars.
But I want to build a keg gas tank for the rear of my 26 touring car. This will be set inside the frame rails and have a bumper behind it to protect it from rear impacts. I believe the way I want to build it into the frame rails will be safer than the old tanks behind the seat in trucks.
Does anyone know where I can find some info to build one of these?
Thanks
Tim
I got one sitting in the shop I started for my '27 bucket, the hard part is getting the hole cut for the bladder. I think it might be easier to get a fuel cell from Speedway and convert the parts to the keg.
Hambiskit, does it really need a bladder? The keg should be pretty well sealed to begin with. I know nothing of fuel tanks so this may sound stupid. But since the kegs are built to hold beer wouldn't it hold gas just as well and only need a filler neck welded on along with the fittings for the fuel line and return line?
the hardest part is trying to empty all the beer out by you self in a day? if you did one tank a day you would need a new bladder:HMMM:i think some one is pulling on you leg

well, unlike beer gasoline is explosive, and it's really hard to seal the tank so that it doesn't leak without one, but I guess you could run without it.
By using the parts from a fuel cell, you get a bladder, fuel door, and the right venting.
I'm still working on mine, but the one we did for a friend of mine wouldn't work till we vented it with a vent cap....then it looked like crap, and the one from the cell is flat.
well beer is thicker than gas but it you put it under psi so think it will not leak i have made some gas tanks from steel and aluminum and used tank sealer in the steel one did not do any thing with the aluminum ones if worried check with air
I was just going to suggest sealer...good catch Pat.
after he empty all the beer out of it he could all so try to fill it back up this would check his bladder:whacked:
I was thinking something like this for a design. Please tear it apart and tell me what is wrong.

put retrun on top now how about a beer
Also in this design I plan on slanting the bottom towards the fuel line in a V shape to force the fuel to the line.
Would it be possible to cut the tank in half make the adjustments then weld it back together? (or in thirds, around it so the welds are covered by the strap brackets?)
Pat, if I do decide to do this I will have alot of beer to hand out as I don't drink anymore LOL, sober 6 years now. Thats why I want to use a beer keg, just a reminder of the "good" times of yesterday.
being round and the pickup is on the bottom it will allways get gas .no i do not any more just having some fun
Ok thats something I didn't think of, Thanks. Thats why I brought this idea up on this forum. Great minds to help me along.
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
That's a good one Pat :LOL: !Quote:

i also was considering doing a keg tank,but i want to put it in the trunk,so it looks like i have beer in there,any unforseen dangers in this
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 upQuote:

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.
