External Fuel Tank
 

Did IH ever offer a higher capacity external fuel tank? Perhaps something that would set off the rear fenders and behind the seat?

Thinking about relocating the fuel tank on of my Cubs - don't know that I would do it, but considering it. Not crazy about refilling the fuel tank over a hot, hard worked engine in the middle of a mow.

Mount it out front. Just remember all the single cylinder cubs came stock as gravity feed so it has to stay above the carb wherever you mount it. kohler did make a mechanical fuel pump that other brands used it can be mounted to a cub kohler with no modification. I,'ve considered moving it to the front I''ve seen a lot of big tractors with a tank like this pic below( could only find a pic of a green one though) trouble is the kohler engine is designed to bow all the hot engine air out the front so idk. I say go for it however you decide to do it and post pics!

I've seen the ones on the big tractors (at least pics), but Wheelhorse offered an auxiliary fuel tank mounted to the rear of their tractors as an option.

Here is of pic of one such tank and that was kind of the direction I was leaning. We'll see. I'd probably add an electric fuel pump to get the fuel over to the engine.

yeah put it on the back as far as I know IH never made one. The only thing with an electric pump is I doubt a single cylinder kohler carb isn't meant to take a lot of fuel pressure. you can buy the kohler mechanical ones new still (just looked them up on ebay 36 bucks)it just mounts below the carb and runs off the camshaft. there is a block off plate right there easy to put on I would assume.

Pullers use small 1-4 psi electric pumps all the time. I got one at Napa before, but can't remember the number off the top of my head. Worked just fine on a stock carb.

Dave Kirk (Kirk Engines) sells one too.

If you wanted to get crazy you could probably mount fenders from a newer tractor that has the tank integrated into it. Might pick up a cup holder that way too!

Or you could use an impulse pump from a snowmobile, outboard, or Briggs and Stratton has them , if it's off of a two cylinder snowmobile you could plug one line or T them together. You can get impulse from the dipstick tube or the breather cover or the fuel pump block plate(not sure on the fuel pump block plate but in theory it'll work)

Forgot about the pulse pump! I put one on my dad's 1211 and it works great! Added a fitting to the fuel pump hole cover like jonjunk said.

Well, looks like you could use a military 5 gallon jerry can side-ways behind the seat.....would look almost like the Wheehorse one. Though, I don't have a sure idea for a tap and filter.

$48.37 steel can

Braze the fitting onto the jerry can with brass. You could braze a hose barb onto the can and use an inline filter, or you could braze on half of a 1/8 pipe coupler onto the can and screw a valve into the bottom with or without a filter screen and you may still have to use an inline filter. It's easy to do if everything is clean and you have enough heat. A propane torch isn't enough heat. Acetylene works great. Just my :TwoCents:

You'd have to figure out some sort of vent too so the fuel will travel smoothly.

To make this a budget project an old metal out board motor tank would be pretty cool too. It would also take some modifications.

One of the things I've thought about was simply relocate the existing fuel tank off the engine. Use it's bracket that's already designed to hold the tank and add bracketry to connect it to the tractor. Whatever I did, I'd make it so I could return the mods back to stock form. See how I like it and go from there to a larger tank later.

I think that would be cool as long as it's not a plastic tank hanging around back there waiting for a stick to poke it.

On a NF CC, I would look hard at relocating the battery to under the seat.
Then using another stock tank and stock cradle, mirror it next to the existing tank and Tee the lines together.
You have now double the fuel.
Looks kinda like stock.
Added weight over rear axle.
And if your still worried about filling it while engine hot, you could have a sheet metal shield between the two tanks.
And just fill the new one to finish the current job.

That would be my biggest concern, to be honest... My Dad was charging the battery on his 127 and spilled some gas on it.. The fire was impressive but he got it managed in time to not cause any damage.

Gas will boil off of hot things (within reason of course... I'm talking about a 220F intake manifold or engine block) in the absence of spark. Seen it/done it plenty of times. Gas and a spark from a battery..? well...
