Underbody Air Tank - looking for ideas

[znelbok Member Find all posts View Profile Close znelbok]

I am looking to put an air tank under the Prado. I have seen a photo of one that was installed adjacent to the gearbox, but for the life of me I cant find it again.

Does anyone know how it was installed or where the thread is.

Any other ideas for a tank underneath.

Thanks

Mick

How many litres do you need.. Another option is at the rear between fuel tank and bumper.

I located a 4 litre tank in a similar position, mine is between the chassis and the side step,
I had to cut the brackets and re-weld a little shorter, this allowed me to squeeze the tank
in between the step brackets, I was Also able to then use existing holes in the chassis to
mount the tank.

Air compressor sits on the draw deck in the back plumed to an quick connect air outlet that
is located on the opposite side to the anderson plugs next to the tow bar.

I did the same as LeighW, see the following pics http://www.pradopoint.com/showthread...l=1#post360125. Mine are bolted to the side with 4 bolts. There was only 3 threaded holes and one blank hole so I welded a bolt to it. They are 2x 6lt air tanks from roadrunner http://www.roadrunneroffroad.com.au/Default.asp

I use my airtanks for my airbag suspension etc

In my first Prado I mounted one behind the bullbar where a winch might go. I found it to be a complete waste of time and effort and sold it and have not fitted one to my current Prado.

Not sure on what size is needed - just something that will help air up tyres a little faster and allow for a bead to be popped back on should it be needed.

How is the tank mounted up the back in that position?

I think you are wasting your time and money , if you have ever pumped up a 4wd tyre with a 50 litre tank on you're average 240 volt compressor , it still takes more than what the tank has to keep the pressure up by the time it gets to 40 psi . It won't really help you air up faster than anyone else in your convoy , it comes down to what your compressor will deliver in free air flow . There are lots of better gimmicks you could dress up your prado with that will be cheaper and much more useful . My 2 dollars worth only .

I have a 10 Litre mounted at rear, 2 large hose clamps and a piece of mild steel bar. Painted up and 2 small 30 degree bends in it. Took all of 45 mins to make the mount including paint drying time.. There is 2 holes in the rear chassis rail that I utilised.

And might I say the train horn is bloody loud mate!

That is something I have looked into as well in the past. Would love a loud horn to wake those drivers up that are doing 20+ under the speed limit because they are asleep behind the wheel.

Secretly that is one of the reasons I wanted a tank, just was no game to say it

Go to the local recycling centre and pick up an old water fire extinguisher. They hold 9 litres and have an air fitting on them to pressurise. Gather some other bits and pieces and make it all work. Just a thought...

I agree with others, waste of time. It will not let you blow up the tyres faster unless you have a VERY big tank. The first tyre goes up quick because of the stored air ,the second third and forth actually take longer because the compressor now has to fill the tank plus the tyre.

There are advantages tough

How do you pop a bead back on without one. Its pretty hard to do with a small pump. (Yes, I have seen aero-start used)

While doing all tyres is slow, they often don't need to be pumped up from flat, just air added for safer road use which can get you to a servo to finish off quickly.

Bypassing the tank is an easy mod for the times you don't want to fill it. All sorts of plumbing is possible. I use a regulator on my lux with it set to the pressure I want the tyres aired up to. I connect and walk away and it stops on its own.

At say 80psi, and tyres at 30psi, you only need about 0.4 x the tire volume to fill it completely.

So it may be something that gets used very rarely, but it might still be on the cards

Have a read here for multiple options http://www.pradopoint.com/showthread...eplacing-tyres none require an auxiliary tank, and please don't ever use a flammable liquid to reseat the bead.
