DIY- Motorcycle Auxiliary Fuel Tank 

It must be frustrating to have so many people comment on this video and not know the true purpose of this tool. Great video. Much more affordable than purchasing an auxiliary fuel tank. Parts List: -- Metal Water Bottle -- JB Weld -- Anderson Metals 57001-0404 Brass Hose Fitting, Adapter, 1/4" Barb x 1/4" NPT Male Pipe -- Anderson Metals 56122 Brass Pipe Fitting, Hex Nipple, 1/4" x 1/4" NPT Male Pipe -- Smith-Cooper International 8140 Series Brass Mini Ball Valve, Inline, Lever Handle, 1/4" NPT Female -- 1/4" or 5/16" fuel line -- Two 1/4" hose clamps

I knew as soon as I saw that power tool that this was a REAL person with a budget solution

Great DIY video. I work on my own Harley and have been needing something like this for when I have the tanks off. Going to look for a used metal bottle now. Thanks for the tip!

I love the soft music in the background, and the slow paced, serene voice-over. Calmed my nerves :)

Got a lawn mower with a bad gas tank, you gave me a great idea to fix it thanks!

That is awesome... very helpful as I need a temporary fuel supply for my motorized bike while I wait for the one I ordered. Ty

Thank you. I just finished making mine. This will be very useful for my current and future bike projects. From some of the comments it appears some of the fellas don't understand how useful an auxiliary tank is. Thanks again.

I just built an 80cc 2 stroke bicycle for a bit of fun and also to take to Le Mans 24 hour race every year to get around the circuit but don't like the stock tank that came with it, you given me a great idea as only need around 1 pint of fuel per outing. Thanks :-)

Assemble the valve and the barb fitting to the coupler before fitting it to the tank and sealing it with JB Weld. This prevents stressing the coupler connection and the JB Weld seal at the tank, which is quite possible if you build the way it is shown in the vid.

Awesome! I gotta build one of these for all my machines! ATV's, dirt bikes and of course my favorite GSXR750. They always need carb work. I was looking at the Motion Pro setup but why spend $50 if I can spend $10. TYVM for posting!!

Great idea. The ONLY thing I would do different would be to tighten the on off valve really tight to the reducer and THEN epoxy it to the tank to prevent cracking the JB weld.

YOU ARE THE MAN! DOING THIS TODAY FOR MY CX REBUILD. THANK YOU!

Great job. Much better than the tank I made out of an old baby bottle haha. Shame about the idiots commenting their bullcrap.

Thanks! I needed this for a motorized bicycle project.

Good solution for when the gas tank is off the bike, and tuning the carburetor

I've been trying to get an external fuel tank for a tank repaint. Thank you for the great too. I will be making myself one in the next day or two.

Thanks to your video. I just made one like this for 10.00 Aother 9.00 and I will be able to have fittings for most bikes. Thanks for a great video.

Great video.

Great idea, great video. Thankyou

+Sky walker Because if it's work doing then do it the right way I went even further and welded a stainless coupling to the tank and added gas rated tubing to mine. Plus as he said its for synchronizing carbs and testing when you are working on them. Not sure if you listened or not.

Very nice bro

If something like this work with a fuel injected bike? I don’t have a tank for the bike.

This is a great idea if you have to do a lot of carb work. Simple and useful. Nice video. Though the title is misleading. "Auxiliary" implies that it's to be used in conjunction with the main tank, which isn't the case here at all. It might be clearer to the trolls if you called it a "shop/carb tuning fuel tank". Thanks for the great idea though!

@carlos Pena Glad to hear it helped .., that was the idea for shooting the video The drill bit and other things you can find at any hardware store

You saw something somewhere. And you're using JB weld. Good Luck

Couldn't you use a 1-gallon thinner can?

what would the benefit of this be as opposed to just using the bottle to store the fuel and pouring it in the tank when you are out of gas? Don't get me wrong, the idea is great as an example of how simple it can be to make your own gas tank for all sorts of purposes. Overall though, great job on explaining and it is a cool diy project

Great great video man helped me out a lot !!!! One question where do I get the drill bit and couplers ?

Did the water bottle have any find of coating or lining that needs to be removed?

Hi, thanks for the guide, what do I do about the vacuum tube?

Question, how to run the vacuum line into this?

How oftem am I supposed to breathe the bottle sir

I love you! Thanks for the the idea

What are the requirement of gas bottle tank

I have some dobts. The gas won't dissolve the plastic cap from the bottle? The gas won't dissolve the plastic inside the bottle?. Because that kind of bottles have some plastic film inside to be chemically inert to water based substances. And very often, the plastic is dissolved with solvents such as gasoline. And, is the gas filtering missing?

What are the materials used to make that auxiliary gas tank?

hello sir.. can u show how to make the return line channel on the bottle?

Don't forget to use pipe dope or Teflon tape on the tapered pipe threads ;-)

Does your bike have multiple carbs? Do you have some kind of T valve down further close tot he carbs to fee both carbs?

Jb weld is not so good , i used it on a tank, dried and cleaned, on a very very small hole , millimetric , only took one week before petrol started eating the jb weld and making it elastic like rubber :/. Tried 4 times, , tried sanding it harder , not a chance

is this bottle steel or aluminum

I'm thinking I'd need at least one gallon. You have any instructions on mounting? Good video.

This is an old video. I know that. But where do I buy the all the tubing and all the metal connecters you had

Great video, this is perfect for use in the workshop 👍. The only thing that spoils it is all the dumb people in the comment section, I sometimes wonder how people so dumb survive to adulthood.

Great idea man!

Hi guys it's only for carburetor, not for FI system

Super cool

Brilliant

ok you all are correct as is this is pointless however i will be using this as THE FUEL TANK but will not use jb weld to hold the fuel that may set my ass on fire so ill use a aluminum valve/ cap and get it welded on .

This would only benefit if you were racing. Other than that just pour it in like everyone else is saying. Creative ....I will give you that

Are you Filipino?

if u put it on the bottom side of the bottle you would still be able to stand it on its own

Brilliant! Tx much

nice vid

THANK YOU LOVE IT

Cool video but perhaps rename it to save confusion.

Or you could save yourself all the trouble and just use an old lawnmower fuel tank that will cost about £5.00 - total.

This is kinda redundant. Why not put the gas in the bottle then just pour it in the tank?

If the plastic ones weren't 50 bucks this would be necessary.

Oh how about you just keep the bottle and pour it in your tank when you run out. Why does everyone feel the need to over complicate everything.

Dude that’s a IV for a dirt bike

I don't see the point of this...

Ah,uh,ah.....

Ahh.. yea ahh.. you know ?? AHH..
