Air pressure regulator for pump-up suspension?

I've found that the pump up suspension in the back of the MY tends to lose air when wheeling ( holds it for weeks when not ). I'm looking at ways to easily ( and CHEAPLY ) re-pump them up to a set PSI.

To me the ideal way would be to have an inline device that vents to atmosphere when it reaches a set PSI. I already have a rear 12v socket set up on a dash swtich so the theory is I'll occasionally flip it on ( with a cheap compressor attached to it ) until I hear it venting.

However I have no idea if such a device exists or if something else would do the job as well. The air hose for it is quite thin and it has a standard screw on valve ( like tyres ) for the compressor so it could be inline either before or after that valve depending on what sort of connectors it has.

So to those who may know such things, what's my best option and where do i buy/acquire this sort of gear from ?

ok you can buy a kit for air shockies ( I have a new one here $25.00 ) has a T with one side of the T a pressure port ( shrader valve ) < tyer valve to you

the PRV can be purchased for as low $13.00 ROSS BROWN SALES NSW but there 1/4 BSP thread

a condor pressure switch 1/4 bsp would be $35.00 , you would need a pressure gauge $14.00 , from RBS as well

or toss the lot as I have a tank ( with pressure switch ) & pump from my 1991 liberty gx for $80.00 + post , in working order as it was the air bags that were shot .

Will the tank and pressure switch allow me to have it plugged into 12v constantly and it will top up the pressure if it goes under say 60 psi ?

I will have to check the cut in pressure ( unless some one knows here ) what the air ride comes in on a liberty .

Yes they run on constant power , controled by the pressure switch .

I post here when I run the tank up

i cant remember hte exact number but im pretty sure the pressure that the controller maintains in the tank is going to be way too high for what your after.

Still might make for a good resivour and then use another controller to actually maintain the pressure in your shocks.

another idea - what if you manually maintained the pressure? mount one of these tanks in the guard and let it keep itself at pressure. then jsut plumb in a manual valve (electric or mechanical) and a guage so you can top up the pressure when needed.

I also have a compressor here thats in excellent nic. been looking to get rid of it for a while. let me know if your interested.
