Converting Beer Keg to Gas Tank

I read the posts in the introduction section that I think was trying to ask how to convert a beer keg into a gas tank.

Iím in the process of doing one of these conversions for my 37 Dodge pickup project and thought Iíd post on the progress. Iím going this route as I feel it is a lot more era correct looking than using a more modern fuel cell mounted in the bed.

First off, beer keg design and the materials they are constructed from have changed over the years and the one you use will make a difference on how you go about doing the conversion.

Mine happened to be a 1958 vintage 15 .5 gallon aluminum keg. A nice feature of this tank is that it has large 1/2" aluminum fill flange where the fill bung on the side is located. This allows me to install the filler neck, fuel pickup and fuel return line directly into the keg without having to tig weld the fittings on like I would with the newer style stainless steel type.

For a filler neck, I picked up a flip top filler neck like they use on boat gas tanks, The cap is vented (and the tank will be in the bed of the truck) so I didnít need to add a vent line. The neck has a flange and is held in place with 4 screws so mounting is a snap after the bung hole is slightly enlarged.

The only thing I have left to do is add a fuel gauge sending unit which I will do after I have the tank powder coated. Iím going to be using one of the slide type senders as shown below.

Mounting a round tank can be problematic so on mine I built a frame for the tank to sit in I still have to build straps to secure the keg to the frame and then the frame will be bolted to the truck floor.

Iím not going the rat rod route on the 37 so I still need to get the keg cleaned up. The thought of spending hours and hours polishing the aluminum (and the constant maintenance to keep it shiny) do not appeal to me in the lest bit. The solution Iíve come up with is that Iím going to send the keg in to be blasted and powder coated. There is a powder coating that goes by the name of ďnear chromeĒ and various others that while it does not exactly look like chrome it DOES look very much like polished aluminum and should be zero maintenance once completed.

All that being said I would warn that converting a keg to a gas tank should be done at ones own risk. For one thing it is of course not a DOT approved gas tank. I will say however in the case of the keg Iím using the thickness of the aluminum is thicker than the aluminum used in the fuel cells I have bought in the past. The other thing is with very few exceptions all most all of the kegs are stamped ďPropery of (the brewer/manufacture)Ē and there may be legal implications using one of these . I got lucky on the one I have as it does not have this stamping.

i would still weld up the tap connection.
or you will be depending on a 53 yr old food grade o-ring to keep your gas in.
while your welding it up, move your fuel pick up there
and weld in a flange for your gauge.

Well at least converting a beer keg to a gasoline tank is better than vice-versa.

All good suggestions but;

I've already drilled and tapped the tap connection for a pipe plug, so the O ring this is a non-issue.

It's a preference thing, I considered using the tap hole for the pickup and made the decision to run the on top along with the return fitting. There is also less of a chance o the line and fitting getting accidently banged by having them at the rear of the tank.

Using a weld-in bung for a screw in sender is not out of the question and Iím still debating on which sender I will be using.

The average newer keg is 5 gallons, but I know there are bigger ones out there. I am looking at switching to a fuel cell in my caddy, would like to do something with a keg but this ain't the project for it.

For the record, if there is a high demand for this conversion, I am volunteering my services to empty as many beer kegs as needed.
