Dumb question -- why not secure the tank under the truck, tucked inside the frame, and then shield it with some scrap steel plating? Then, it's out of the way, not taking up space in the bed. Either way, that's pretty cool.

 

Not a dumb question at all. That has been a location considered for a long time. I already have the spare tire out and don't plan to put it back. That location is suitable, however, I don't want to chance the differential to say hello to the tank under compression. Likelihood is low, but I don't want to chance it. Other consideration is that I wanted to be able to access the tank easily for removal. For me, I won't be compromising too much bed space. It will not go down on the floor. Two locations on my mind are the 1. top of a wheel well and 2. Front of the bed side, like below the passenger window.

The location will probably be finalized when I determine the mounting brackets, which I'd like to function similar to bike mounts with a quick release. Tank has two feet with mounting holes. Thinking to weld a handle to the tank for hand carrying.

Underneath could still be an option though. I'll snap some more pics when I'm closer on that aspect.

 

Your gas tank is under there as well so I wouldn't be too worried. I would however keep that tank deflated (empty) just in case the bad happens

 

The word you were looking for is "depressurized".

 

Im almost positive that all of the trucks with air systems that we use in the CF have what is refered to as a wet tank between the compressor and reserve tanks. It builds air and gives a little "wet fart" after a few minutes of operation.

That being said, just making sure you drain the tank when you are done using it and again every morning, because condensation build up from temperature changes and such, you should be ok for what you are using it for. Its not like its for your brakes.

As for location, I would prefer it in the bed as well. It looks like you have a cap on your truck and having the tank out of the elements and away from sharp rocks would be nice.

But I'm no expert!

 

or, maybe.. 'disarmed'..

this is a dang good notion... melikes!!!

 

that is pretty cool. i am working on welding up a headache rack for my truck that can be as an air tank. just need to find a cheap air pump or maybe take the a/c compressor off my one truck and install it on the other. it use to put out way more than enough air to clean out a computer.

 

Errr....any chance you've seen the clearance relationship of the axle and the gas tank?

The tank I have, due to its size, could only be mounted in the spare tire area and not alongside the driveshaft. Also still too close to the driveshaft anyways. Even it were pressurized and got smacked, I think I'd rather have it underneath anyways....



That's some good points you have there. More and more the wet trap would be more necessary for a system under semi-constant use, such as the example you provided. I only plan to run/fill my system when the need arises. No intention to keep it constantly pressurized. Being mindful of draining remains a valid point.

As for the cap, that is my cargo pod.



What notion? You have me worried given your wallOtexts.


Good idea with the rack. Only thing to be mindful of, which I'm sure you are, is leak checking that thing due to number of welds you will end up with. I like the idea though as it's along the same lines of bumpers that also act as a tank.

As for the compressor, afaik a York Compressor is suitable as opposed to the A/C. IIRC the seals being suitable for air tight (hermetic). Nab a York out of '80s Volvo from a JY. This has been a common formula for OBA setups too. 4x4help.com actually documents quite a few.

 

yup.. that would be me...

I think the notion of having on board compressed air is a dang good one, especially if you off-road with any regularity..

 

Is that a euphemism for someone has diarrhea?
