I want to fit a second spare tank somewhere in the Patrol. I don't have much room left under the bonnet so can this be mounted under the car and away from rocks and things when I go bush bashing?

Basically I don't want to buy another air compressor as I am happy with the ARB one. It just takes a little longer to pump up my tyres, but it's mainly used for the air lockers. So can I some how plumb the hoses to pump the air into the bigger receiver tank and then run the tyres from the bigger tank and the lockers from the standard one?

I have been using my spare tyre on the bake of the car .
You need to make up a deecantng hose and put about 75 - 80 KPA in the spare.

This will put enough air in the fat tyre aswell as leaving the spare tyre ok to use the pressures will become =

You can also top the 4 main tyres up to road pressure if you have been running on the sand.

Truck wreckers, wander around until you find a tank of the size you want, quite often come with fittings and relief valves etc.

Yeah I go this one from the truck wreckers, painted it up, works great of the bluetounge with an ARB pressure switch.

All you need to do is run a hose from the compressor (via a "T" peice) to where ever you want to other tank to be. The ARB already has the pressure switch in it. Just keep it charged all the time (if it's big enough it'll hold charge for a week or so before it needs to top it'self up anyway) and whamo all done.

You have to remeber though that it will actually slow you down after it's equalised the first tyre. A good idea is to get a truck horn solinoid (about $15 bucks) and fit that inline with the big tank so you can just flick the tank of once it's empty so you don't have to fill the tank AND your tyre after it's empty.

Same here as BBB

If you think about it , a tyre is around 60lt and a standard compressor tank of 24lt
doesn't go a long way even at 100psi.
Ok if your building a comp rig but a bit awkward in touring car.

The spare tyre system has its detractors but it has the same capacity as each other tyre and is easy to work out what it can do.

I.E. if your tyres are 18psi and spare is at 68psi then you can pump up
each of the others by 10psi and all 5 tyres will be at 28psi which is
enough to go home or get to servo and this is what tends to happen in practise.

Hence transfer hose from spare tyre ,as has been described here before is a
very practical device.

Using a screw on attachment to the tyre is the best way to go , and remember the best air comes from other peoples tyres

Just buy a truck air tank and mount it under the truck, 1000's of others do it without issue.. check out Woops truck on Olimits.. he has 3 tanks with an outlet on each corner with endless air.

Dive tank laying down on the floor of the rear cargo area. Costs $8 to fill up, but will give you heaps of air. Should be cheap on Ebay. Be VERY careful not to overfil the tyres through, theyr'e up to 40PSI in no time!

Hello Troll,
I've got one of these, Tank mounted between the chassis rail and the gearbox, above the gearbox rear crossmember. The one I bought was as this auction describes, a factory second. What that means is in the case of mine it comes with the first scratch as standard.

D-Jack mentions a SCUBA cylinder for inflating tyres. I use one of those too for the same job. Down sides are its weight and size on a long trip. You've got to fit it and leave something else out. The other problem is you must by law posses a SCUBA diving certification for the shop to fill the cylinder with high pressure air also I've never ried to get a SCUBA fill in Birdsville but I imagine it would be challenging.

Thanks Geoff

The tank looks nice. I don't like the idea of a scuba tank in the back of my car, I already have so much stuff in there and I have seen to many movies where they use those tanks to blow things up...like yaws....:)

Yes well, as you are well aware there is a fair bit of "Hollywood Licence" in exploding SCUBA cylinders and dead sharks.
Down to the point of if that SCUBA cylinder in Jaws was full it would have actually sunk like a stone, not floated nice and neat over to the guy to use on the yakka.

Hi Roachie,
The link I posted to EBay is for two of those tanks that are factory seconds. They'll come with the first scratch free. So for a starting bid of $155.00 you'll receive two tanks.
He sells the first quality products in his store for $175.00 each.
I think that answers your question.

I think I paid about $80.00 for mine including freight from the same guy. Mine is a factory second. I wasn't the slightest bit worried about the scratch as under the Troopy I'm expecting it to gain a couple more.

No problems, it was probably a poor example going for the double auction straight up.

That setup Jeff M from WA has a couple FollowUp's above is a beauty.

Must be somthing in the name! Even if it is spelt wrong! LMAO!

It's acutally quite effective too, I carry the rattle gun around with me now in the tool box cos that tank can take all 6 nuts off a wheel before it runs outta go. It'll also pump 1 x 31" MTR from 16psi to 32psi within a matter of seconds. Then it's time to disable it and start pumping the other 3 the "hard way". Once I've finished, just open the tank back up and let it fill back up while you drive. The air horns are cool too! LOL!

I put a pressure guage on the dash so I can see what's going on with the tank, but you can also use it to monitor how your tyres are going while you sit in the air con.

I use 2 tanks (a 3L and a 4L {approx}) which I have mounted in the back of the Patrol, up high on the cargo barrier. The twin compressors are just below, sitting on the single drawer system, above the left wheel arch. They feed the 2 tanks via a 3-way brass joiner and then have outlets going to front and back of Patrol.

In my experience, even with these 2 tanks (admitedly there is still not that much volume available), there is no real advantage when trying to air-up tyres. The compressor/s very quickly cut-in (cos the pressure has dropped to 80psi), once the hose has been connected to a tyre.......it's only a matter of seconds.

I will be able to test out this weekend how much quicker the 2 pumps together, make the job of airing-up.

Yeah I origionally had a 2L tank and it was great for air horns but that was about it. This one I'm not sure of the size, but it's bloody massive compared to the other little one. I'd be guessing this one is at LEAST 12 litires, maybe more. The Blue Tounge suprisingly doesn't seem to struggle too bad pumping it up either...

What are the two compressors your using?

G'day Jeff,

One is a Maxair (about 3 years old), the other is a new maxair "clone"; claimed 72 litres/minute etc. They are very good and did a great job airing up my 6 tyres plus 2 of Pesty's, quicker than his ARB could do the 4 on his cruiser!! (but he did have a blown fuse for a few minutes.......but, also, I blew a hose off it's fitting too; so I guess we're even on the "yeah, but" stakes, eh?)

In my Ptrol I have a stainless steel stored pressure fire extinguisher mounted in the winch space of the bull bar. They don't rust and can be safely pressurised to 120 psi. They can often be found hanging about !

People,
haven't heard anyone mention a LPG gas cilinder. These also hold good air and fit very nice under the bull bar below the winch.

Hi All

I have put a lightweight tank on my cargo barrier near the bottom behind my fridge, it is supplied by two pumps, the ARB one and one of those big black ones that I have put into a hole beside the draws and in the gard.
The tank has a 10mm line running to the ARB tank so the pressure switch turns on both pumps and all runs of the ARB switch one the dash, I can also isolate the ARB so I only turn it on when pumping up tyres.

I use it for everything even have a small coil hose with a air gun on it and blow all the dust of the back before I set up camp.

Have fun

Remember though any tank should have a pressure relief valve set at an appropriate pressure, having seen what an old truck tank did to a ute body when it went off underneath at about 150psi!

Absolutally! You can see mine on my photo's on the RHS. I installed a small tank and Bluetounge on my mates Jackeroo the other week. I insisted on the 150psi relief valve. Good job too as he blew the relay a week after it was installed (it was a cheap and nasty one) so he replaced it and hooked it up wrong. He started the car and drove off, the pump was connected permantly to 12v. Driving along and PPPPPSSSSSSHHHHHH! The relif valve went off.
