I have my hilux booked in at ARB to have an air compressor fitted in the engine bay and am thinking about having it hooked up to a tank I have behind the bullbar.Some people have told me that I should just have it going to an outlet at the bullbar.Can someone with a bit more knowlege advise me on the best way to go.
Cheers

G'day mate,
Having a tank is a good idea for a few reasons. (Note that I don't call the 500ml jobbie on the ARB a real "tank")......

Firstly, it'll give you a reserve to use if you want or need to blast dust out of a air filter or brake drums etc.

Secondly, you'll also find it better for re-seating the bead of a tyre after you've repaired same.

Thirdly, if you ever want to mount a decent set of air horns, you'll have a great air supply to run them (none of those dicky little Fiamm type efforts).

Lastly, if you fit air locker/s you've got the air there already (although the ARB tank is okay for that purpose anyway).

I would think twice about having it fitted under the bonnet due to dust and moisture concerns. I have a mate with a 3 litre Patrol and we mounted his against the firewall (it's an automatic). He didn't use it all that often and it seized up on him. He's now moved it to the back of the cargo bay. If you can fit under a seat or somewhere, I reckon you'll be better off.

Good luck

I have mine fitted under the bonnet, drivers side corner. Its a very neat fit and ARB had to move some stuff. It stays clear of mud etc and is very easy to connect to.

Thanx Roachie some of the ideas you mentioned are what i was thinking of.Do you think it would run a rattle gun for changing wheels?

Mate, I haven't tried it, but I wouldn't expect my small tank to run a rattle gun. I'm keeping my eye open for a 9 litre fire extinguisher and would like to substitute for my existing one.

What do you want from the Tank.??

What do you want it to do, inflate tires, lockers or what...??

ARB compressors arent the best for running air tanks depending on volume, they WILL do it, but will wear out faster than other items...

Depends on what you want it for, and your budget.

If money is no object, Clisby's are T H E kit to have, they wont die ever either, but you do pay a bit more for them..

Max Air, Blue Tounges, etc are all about as good as each other, the other top idea is Endless Air. But they dont fit every car.

I also think warrenty gets affected by having tank. I bought the ARB compressor today and the owner of our local 4wd store said it voids the warrenty because of the back pressure???????????????

Sparkie,
Back pressure issue can be overcome by putting in a one way valve which is what I've done on my max-air set-up. Compressor pumps up thru the valve and pressure is stopped from returning back to the pump. Works really well.

You would be advised to have a relief valve in the system or a max. pressure shut off solenoid switch otherwise you will have backpressure problems which could overload the compressor. Cheers.

G'day Topcat.....Should have mentioned that I have my set-up run through a ARB pressure switch, also have a pressure relief valve and also have a pressure gauge mounted on my "A" pillar....so I think I've got all the bases covered.

I have a tank and a blue toungue (rated at 100psi) set up with a check valve and a 80- 100psi pressure switch. When I am 5 min from leaving the beach I switch the compressor on so I have a tank full of air to use which I find is good for the first 2 tyres at servo speed then the other 2 at blue tongue speed. This raises another question though. The last 2 tyres are being inflated at the same time the air tank is being reinflated, this is taking longer than just inflating a tyre (I don't think it is that crititcal). The compressed air is good for cleaning dust out of parts though.

I guess it depends on what size the tank is as to how many tyres it will do.How long does it take to pump your last 2 tyres?

Allan,
It depends on what size tank you have. Mine is only 3 litres so it doesn't make much difference to the whole tyre inflation process. By that, I mean it doesn't help much at the beginning as the compressor cuts in almost immediately when I start inflation even if the tank had 100psi to start with;;;;also, the compressor doesn't have to work much harder once the pressures have equalised. However, if you have a 20 litre tank then you are quite right, the compressor is trying to inflate the tyre as well as fill up the tank. Some blokes avoid this by having a simple shut-off tap on the tank, so that the compressor is not trying to fill it too.

I have a 5ltr tank under the LC100 which is enough to take a tyre from 25 to 35 psi - just. Not much use really. So I also have a 20 Ltr tank the plugs into the air line either inside the back (I'll be making a place for it when I build in the drawers) or on the trailer via a coupling on the towbar. I didn't go for a connector on the bull bar because it would require a longer hose to get to the trailer tyres - the towbar made more sense for me. The 20Ltr tank has a handle on it and a tap that allows me to disconnect it and take air to the location required.

I'm very happy with this set up.

hi all,

for those considering putting in a small tank hooked up to their compressor I thought I would share what I am in the process of fitting to the 80 series.
Big W have a 240 volt air compressor for $68. it has a 6 litre tank( pressure rated). and it was also very easy to modify the pressure switch from 240v to 12v.
I have used a Repco 150 psi HD compressor($99) for the last couple of years and am happy with its performance.
All has been bench tested and works fine, tank pressurises to just over 100psi and compessor cuts out.
tank will fit behind front bull bar on left hand side with outlet under wheel well,
Compressor goes under bonnet on left hand wheel arch behind fuel canister and pressure switch goes in behind it in the back lh corner.
only got compressor in last sunday, tank will go in next just need a couple of brackets .
best thing is all up $99 for compressor, $68 for rated tank with bleeder /relief valve/quick connect outlet and pressure switch&Gauge, 5metres of air hose and a couple of extra quick fit fittings $30 at bunnings under $200 all up.

another bonus if you dont have acompressor in the garage,as this particular compressor is belt driven not direct drive the 240v motor and compessor can be mounted in the workshop for a straight air supply.makes it even cheaper

Sounds great I often wondered if this would be possible
how did you convert the pressure switch?
