Comet has these for $25, 5 QT, probably out of stock constantly.

Looks like you should be able to use a Wald $10 rear rack and that pretty easily, if you source something for a brace under the rack tubes. other $15 racks that have the flat alu or steel plate in the center, should work by drilling the appropriate holes and adding some hardware. It's only 2 bolts and comes with a petcock.

I'd bolt that tank to a top tube before I'd even think of mounting the peanut tank to a top tube anymore.....seriously.

(10"l x 7"w x 9"t)
(12"l at the mount tabs)
http://www.cometkartsales.com/store/chassis/cpa/fuel.htm from this page, no specific link now bc. its out of stock. Call!

I'd recommend some kind of clamps or brackets then! 1 gal of gas is about 8 or 9 lb. So the whole rig is going to be heavy, and it's meant for a flat surface.

The wedge shape is awesome though. You might be able to get it in some diamond frames if you have a front or rear engine like a Dax.

This MIGHT fit inside metal ammo cans! Measure twice!

on the back, even better!

Make this tank for $10. If you want to paint it, scuff the whole thing (new) with 3m green kitchen scrubbies, wipe down, and use Fusion paint. Let it cure 2 days! It works.

personally I see where the Beverage distributors have now been putting there beer in the mini kegs. Im going that route when I finish the beer. LOL

 

[flmotorbikes]

Good idea. I've done that with one of my friction drives just beware of the vibration if you have a 2 stroke

i have considered an automotive fuel cap and filler neck from one of the old cars in my back 40.
cut filler neck off and weld to whatever tank i build.
another one is crank out something on my lathe,with an inlet valve to let air in so fuel will drain out petcock.and a check ball to keep gas in when its sloshing.
i have a couple old coleman cookstoves,the filler is a nice size.

oh.forgot why i was here,like the bike,the ammo box idea is cool.
aftermarket snowmobile parts suppliers have rear fuel storage tanks,roughly one gallon.
cap and gas line fitting ready to go.

 

[happycheapskate]

If you cut the fuel neck from an old mower or tiller (briggs or tecumseh), you can find new vented ( 2 way) caps for cheap.



Here is a check-ball vent I made today for $0, but the check-ball shuts off fuel flow if there's no return hose from carb. Best to use a motorcycle dirt-bike tank vent ($10) for gravity feed.

My home-made vent (without check ball it works, but can leak fumes when parked)

Motorcycle vent $10 for good metal one

2 or 4 quart Tecumseh snow blower fuel tank, screw bosses on top for tank brackets, $10-30 in mower boneyard and AMazon

Some dude put a pocketbike tank on his FD. This doesn't look too bad!
Maybe if you find a crapped out or wrecked pocketbike on CL or EB, you could get a tank, headlights, battery, blinker system, switches, levers, fairings, maybe even a running motor.
Most of the pocketbike engines can mount straight onto a Dax FD.
I saw someone put the fairing with headlights from a pocketbike onto a mountain bike. It was a little wierd but it worked!

I'm not sure how it is mounted though. I think most pocketbikes have 1 or 2 center tabs on the tank. Maybe he has an L shaped bracket.

I like the back mount. As for that ammo box, fish tank sealer? around the edges and fabricate a cap so it doesn't open the whole thing? Not sure if it will work As im thinking but ifs worth looking into I think.

Just remember you are dealing with a volatile and explosive fuel that is tied to an internal combustion engine powered by a sparking ignition. You could possibly weld an ammo box after making the tank neck. It seems a better idea to install a plastic tank in there.

Liquid ammo? Ammo cans look cool and all but they are not meant to contain liquid. Used to contain proper liquid containers, I don't see a problem with that at all. Use your head when dealing with liquid explosives....seriously.

I bought a NOS B&S gas tank from a lawn mower parts supply on eBay. Mount is steel strap from Home Depot painted semi-gloss black. Total cost with fittings and hoses etc has been about $90. Holds a gallon.

 

[Kermit42]

An ammo can is made to hold explosives. Put...mount a plastic gas tank in there and call it a day. Now your gas tank is reinforced.

 

[happycheapskate]

Yes, I covered a few plastic go-kart tanks that fit inside ammo cans.

so,i cut up a bunk bed for my buddy,to make it a raised bed,no second bunk.
i had this pile of bent pipes,wondering what to do with them.
i sectioned out two of the bends,welded them to a third one that was on a 20"long pipe
lined it up with the top tube,and elbows turn up and to the right,beside the handlebar stem.cap is from an inflatable boat,chrome plated brass.
it happens to have a 2" diameter base,and after tinning pipe and brass,it joined nicely.

turned a block on the lathe for seat post end to take an engine mount bracket to hold it on to seat post.threaded it for 1/8"npt.
will post pics tomorrow.
it wont hold a lot of gas,but i dont go really far anyway.

 

[GearNut]

I am looking forward to the pics, tooljunkie.
Your tank sounds interesting!
