ARB air compressor under bonnet on 4.2 GU.

Darian great picture of the wagon, who's the mascot on the front??
But I'm really interested in the 5L PVC tank in bull bar - where did that come from and what PSI does it take, is there a safty valve, fittings, etc ???
Would appreciate any info - taCarpe Diem

That's her indoors who will be included in all sandy expeditions to great fishing places (Fowlers Bay, SA).
Re the PVC tank, I got some high pressure 50mm pipe from the plumbing shop - costs a bit - rated to about 135 psi I think - made some brackets and mounted max length I could fit in under the bull (I have an ARB non-winch type). Got some fittings (a Tee, threaded hose coupling etc) from an Air Tools type shop (Beissbarth in SA - they serve the tyre changing industry). ) Put a Tee onto the ARB pump fittings to gain an extra pipe and ran that down to the PVC tank with some rated hose.
Might have been $60 all up. The extrar tank space allows for some decnt "blow" in reserve. I have a snap on tyre inflation fitting and a blow down gun for cleaning dusty things while bush. The original pressure cutout is undisturbed. I'm happy. Your point re switch in engine bay is valid - as you say, we have to go there to use the pump in the first place, but its such a nice switch with a great loom so I stuck it indoors. Bought another one of those switches from ARB for the Lightforce spots.Love the bush - stuck in the city - help.

I like your thinking, particularly the fishing mascot idea. I just returned from 1 W on Melville Isl. and didn't take the mascot but caught trophy Barra instead.
More Q re tank - Are ends closed with PVC glued caps ? Have you fitted a safety valve or is the tank rated higher that the pump ?

Could you also include a tyre valve fitting so that you can pressure up from garage air hoses ?? saves a lot of work by the little ARB, but you would definitely need a safety valve & know the PSI capacity.
I use my spare(s) to carry extra air and have a clip on hose to the tyre valves with a small ball valve near one end that turns on after the connection are made. I will make up a short adaptor for a blower.

Yep - the hight pressure PVC tube has the same rating for the caps - just cleaned them with metho and used the regular blue cement. Don't stress them for 24 hours - all will be fine. I put the brass inlet fitting in the middle of a cap. Its a hose type connector with a threaded base (for tapping into a metal sheet surface or similar) - with a fibre washer or two, it sealed nicely. The tank is definely rated higher than the pump - by about 35 psi or so - they can tell you at the plumbing shop. I don't think there would be much point in storing air in there - the capacity is too small (5 or so litres all up). Your tyres are a different story all together. Before this project, the "blow" was about 4 seconds worth using my blow-down gun - with the PVC tank, its out to about 15-20 seconds max. A small but useful improvement. Use the biggest diam and length you can fit to gain litres - it will cost but its worth it. Love the bush - stuck in the city - help.

Thanks for all of that. From little acorns grow big oak trees.Carpe Diem

I'm not too sure that the supplied rocker switch will actually fit in the available blanks inside. The thinking with regard to switch under bonnet is that you go there to connect the air hose so you might as well turn on and off as well! Saves getting back into the vehicle each time. Another query, if the pressure switch fails will the small tank self destruct?

They are a big looking switch!

But yes they do fit. One thing, ARB wouldnt sell them if they didnt fit. You may have to file the hold a "LITTLE" larger, as some are tight fits, but mine was fitted month or so ago. its a big switch with ARB on it, and few lumpy bits sort of like for grip.??

Take care.

Thanks for the feedback guys, I will now sort this system out!

Thanks John, the info you have given is great and I will probably fit as you suggest. I will also look at the small tank idea and may run airhose fittings from the bullbar area. Thanks again!
