Default LIGHT WEEGHT FUEL TANK

I am looking for a real light weight fuel tank .75 to 1 ounce. The tanks at the local hobby shops seem very heavy for their size. What tanks are you guys using?

Here is one adaptation -- however, a search on "fuel tank" in this forum will yield several other good ideas from the guys here.

What is different about a Fuji? And how do you identify it? The lady at the drugstore offered to let me look thru the trash-bag for anything I wanted, but none of the film cannisters were marked with a trade name. All sorta looked alike to me.
Thanks,
Al

The Fuji cannisters are clear and the top fits into the lower portion rather than over the lip like the Kodak cans do. There's another brank of film that uses tops that fit into the lower portion but they don't snap in as well. The Fuji lowers have an inner bead around the inside lip of the lower portion and a matching swelled lip on the cap. They snap home quite securely.

John,

That is good news for me as I have a "game" camera that recommends you use only Kodak film. Since I am mostly using digital for everything else, the Kodak can supply is good and the Fuji bin in kind of empty.

I found the Kodaks (black and grey or all black or lately whitish with blacktops) did not seal quite as well as the Fuji's for my uses. But as long as it doesn't pop loose it'll stay sealed just fine. YMMV. Be advised that I have not tried using them for fuel tanks so far. Just keeping paint and other stuff in them.

I always seal the lid on with a bead of gun silicon- I have never had one leak or come apart on me running muffler (almostno) pressure. For my last muck about plane I cut the bottom off one canistor and made a double tank from two. If I was going to make it again I`d melt the two halves together with a soldering iron. But it did the job just glued with silicon.

Someone had a great idea about making your own tank from sheet stryrene- seemed extremely good to me.

Goop adhesive sticks really well and is TOTALLY fuelproof. Much better than any Silicone I have found.

J-man, it may not be technical, but believe it or not, that's the name that's printed on the tubes label.

I recently made a fuel tank out of a small pill bottle. I'm guessing it holds about an ounce and my Sure Start ran for almost 6 minutes.

Yep. If you don't need any kind of pressure set-up, it's just too dang easy to use a 9" helium baloon tank. I just wish that the old Jim Walker Firebaby baloons were still available. That material would last "forever". ................ George K.

I like the 2 oz Hayes tanks and small Sullivan fuel tubing.

Perhaps a dumb question and sorry if it has already been addressed here or elsewhere... Is a traditional soft line into the bladder with a weighted fuel pick-up unnecessary or even detrimental to the operation of a bladder? Is any line extending into the bladder desired or will the walls of the bladder just suck up against the pick-up tube?

Nope not a dumb question. A clunk is not used with a bladder, the principle precludes the need for a swinging pickup. A dip tube might be used with larger bladders in case they fold forward and trap fuel. With the large neck diameter and small capacity of balloon tanks, I don't think a dip tube is necessary. In theory it isn't because you are aiming for a void free fill. First - with the pickup of the tank at the top, which is usually nose up - you suck out the air which floats to the top of the fueler, then you fill the bladder* with air free fuel from the bottom, stopping before you fire air into the bladder. Then if you are really diligent, you tap and shake the fuel lines/nose of the model, then draw a little fuel back to suck out any stubborn air bubbles. Then connect to the engine.


* not to be confused with a pressure bladder = inflated tubing

Okay - thanks very much for the explanation - I think I'm getting it. I surmise that once the engine is started and suction begins with no air in the system - it should be able to suck the bladder completely dry.

Should the C/L of the bladder be roughly centered about the entry point on the engine?
