Anyone used an air tank for fuel?

I thinking of using a moon type tank for gas, but my budget is making me have other thoughts. Has anyone welded some bungs on a portable air tank and made their own gas tank? Pictures...??? Thanks

 

ive seen it done manny times at show ive gone too, wouldnt see why you couldnt as long as it has a good seal on all the fittings, it the tank can hold the preasure of air, i think it could hold the fuel, ill see if i can find any of the photos for you

 

Ther's no reason why it wouldn't work. If the the air tank is steel and used, I'd check it for rust on the inside. Clean it out well and you should be alright.

Yes, they work good. I've seen quite a few. I even have people that ask me why I have two gas tanks. They can't imagine my air tank being for the air horns.....

 

I would use some tank liner because the airtanks are usually unfinished inside.

You should be able to find some KREEM or the like at a motorcycle shop.

 

The liner sounds like a good idea. You can buy an 11 gallon portable air tank for less than $50. Does anyone know if the liquid capacity would be 11 gallons also?

 

I understand Kreem is having problems with E10 fuels...maybe POR15 tank liner instead?

 

I would use the stuff Bill Hirsch sells, guaranteed to be okay with e-fuel.

 

Yes. It is a volume measurement.

 

If it is a true 11 gallon tank, you should only put 10 gallons of gas in it. 10% needs to be left for expansion. Otherwise, it will puke fuel on a hot day.

 

what about baffling ?weight transferring when turning corners ?

 

I have a propane tank on my T right now, works great just maybe little small. I was going to run a spun aluminum but thought it looked too dune buggyish for me. I am getting tired of people asking how I got it to run on propane so I am putting a stock T tank on it now...

 

Boats dont have baffles in their tanks ,So dont worry about baffles

 

Trad 27 maybe you could tell them propane is a clean fuel and they would walk away feeling green and fuzzy about Rodders.

 

Good idea, until they see all the black on the side of my bucket from the lakes headers, lol

 

The black on the side of your car is just your carbon footprint.

 

I dont see why it wouldnt work, but I would suggest picking up some fuel cell foam like they use in racecar fuel cells as a precaution

I'd say use this just to keep sloshing down so you dont put any uneeded stress on whatever mounting setup you come up with, especially is you weld some mounts to like an aluminum tank, that shit'll probably crack eventually.

 

Here's a bomber drop tank that is commonly used for fuel. They hold approx. 10 gallons. HotrodWorks carries the gas cap and add a couple bungs & clear hose for a sight gauge and your on the road.

 

I,m using a air tank with kreem tank selant and my motor runs
of methonal no problums with the tank yet

 

Try going to your local small engine repair shop. They will probably have some old air compressor tanks, and they will differ in size and capacity. Be sure and check them over, because they will usually have some rust on the inside, but just besure that it is not too bad, and then seal it.

I use one in my coupe. No problems.

 

I've got what I think is an old air tank as the fuel tank on my 1954 International S180 logging truck. Complete with plumbing fittings as the fill (you even need to use a pipe wrench to open it), and a modified grease zerk as a vent. Oh the things old farmers cobbled together...thanks gramps.

 

Here's how to calculate the gallon capacity of a cube or a cylinder:

Check this link: http://www.greertank.com/tankcalc.htm

or if you want to brush off your math skills...

L x W x D = Cubic Feet (for a square/rectangular tank)

Cubic Feet x 7.47 = Gallons



if PI = 3.1417, and Radius = 1/2 Diameter, then...

PI x R² x D = Cubic Feet (for a cylindrical tank - like an air tank or Moon tank) and "Cubic Feet" x 7.47 = Gallons

(the "R2" above is "radius squared", or simply "radius times radius")

Hope this helps!

 

Wow! I never considered an air tank.
I think sloshing may be an issue if the tank is long or wide, but since the air tank isnt long or wide, I wouldnt think it would be a real problem.

 

What are you guys with (fuel) air tanks useing for a sending unit?

 

I'm using the ol' "carry-an-extra-gas-can" sending unit.

 

No on using the foam as a baffle.
When installing a fuel cell that has it in there we pull it out.
It deteriorates and will end up in your carb.

 

Ive heard nothing but bad things about "kreem".

 

Have you thought about using an old tractor fuel tank - there's a thread on a 28 Modified built in Australia using a really neat one from a Fordson - a lot nicer than an air tank and comes with a built in reserve;
