Yeah. I wasn't really ready for the spring in there. Sort of caught me by surprise. It was pretty heavy.

So after a couple of days of having it all working, I'm surprised by how often it adjusts. I find about every 3rd time or so I stop at traffic lights for a while, it adjusts. I didn't expect it to adjust so often.

If I was doing it again, I probably wouldn't worry about the air tank. Yes it makes the adjustments and the off road mode happen pretty quick but I doubt it's really worth it. I mean how often am I going to use the off road mode and do I really need it to be that fast. I'm also finding as the air tank doesn't really hold that much air and the suspension adjusts pretty often, the pump does come on pretty often. The worst part is because the pump comes on at 110psi and off at 145psi the pump really isn't that efficent at that pressure so it has to run for 10 - 20 seconds to add just a little bit of air to raise the pressure in the tank.

On an Air dryer.

These would be perfect. They are cheap enough that I could replace them at each service time the down side is the freight they want to charge me from the US. If anyone knows where I could pick them up in Australia, let me know.

That stuff can be dryed. In the oven on as low as it can go, door ajar overnight. Color will change when ready. Problem is you don't know the volume of these and if they can be emptied and refilled.

I can put you onto someone to supply just the color change desiccant as well, in min 1kg tubs. Was around $30- I think, just use a std in line water separator and fill it up.

Thanks mate,

I'm going to have a look where I can mount a water seperator. I might look at having 2 back to back. One to catch/sperate water and the second with the silicon beads.

I might PM you down the track once I get it sorted, if I need some dryer silicon.

I have a tank fitted to my disco 03. This is for inflating tyres and running air tools. (Trady) thinking of using a feed from here to do the same, thoughts?

Go for it. Easy as. You only need 2 valves and a "T" peice. One to let air in (replaces the whole compressor) and one to let air out (replaces the exhaust which is part of the compressor).

Oh you might need a regulator. If like me you use cheap valves, they wont open at too higher pressure. You can pick up a regulator and valves for less than $10 ea from eBay.

If you have a compressor on board and it already works automatically with a pressure switch. $30 is far cheaper than a replacement WABCO.

Happy Days.

My version consists of a 9l tank, engine driven air compressor, Wabco a/c replaced by 2 x 2watt solenoids.
