Default Anybody?

I've been told just about any air pump will work, thats its not tied to the cpu in any way, that all it does is fill up the air tank. I'd need to tie in the remote on/off switch somehow and a hot and ground, and I be good to go. Is it really that simple?

Default well maybe a Ford pump but ...

There is talk on some of the boards about a Ford pump for the Mark Trucks and the like that is physically mounting wise similar to the pump on the 3. The trouble is that it just seems to be talk.

If there is any problem with the air system, it is that Land Rover is about the only manufacturer to run the compressor at about 250 psig. Everyone else, including the semi trailer guys run at under 150 psig.

That is hence, the basic problem; no one, (including LR), knows how to build a reliable, (lasts at least 4 years until the warrenty runs out), pump that operates at about 250 psig.

Running and storing air in the tank at the high pressure has the advantage that when the truck lifts, it does not do the camel thing like the earlier Range Rovers - lifts first at the front and then the rear. There is sufficient air in the tank to do the lift on all four corners at the same time.

What is interesting is that the air springs still operate at the lower pressures, (about 100 psig), so you do not need much more pressure than that to actually function.

Some are installing a second air tank on the other side of the 3 to add to the stored air volume; with that done, then a lower air pressure compressor is practical, assuming you can override/reroute various software signals between the ECU and the factory compressor.
