That worked out well. I bought a compressor off eBay for £30 from a BMW E53 X5 with air suspension. I'd wondered if it would perform better than my tired old one and be cheaper than even a refurb kit would be. It's great.Waterproof too, with a 10mm pipe for air intake. Quickly got up to my normal 4 bar pressure.and now adjusted up to 8 bar, so that should be good for the pneumatic seats if I ever get to work on them. I fitted an air filter: RangeRover P38 (£5.99 from Ebay) on the end of the inlet pipe.Which sits about 300mm above the chassis rails.

Replacing the Air bags Quite an easy job for a main suspension component. I'd already got one bag from Marcel Leisure. I ordered a second one. Free delivery, and it arrived at work within 24 hours - all ready for the weekend. The main issue was the size of fittings, so I'll give a detailed parts list at the end. The bags are Firestone and have UNC and UNF bolts and NPT air connection. I'd only managed to find a UK source for the bags two months earlier - rather more convenient than arranging a delivery from the USA, and at £105 incl VAT and delivery I was very pleased. NPT fittings came form an Amazon supplier strangely. And UNC and UNF bolts from Southam Agricultural supplies: New bag and piston assembly Bottom view All the bits and pieces Fitted and inflated. Fittings in place The parts

All back together. Pumps up to 8 bar easily and holds pressure over several days. Really pleased. The bits All back together New bush New releif valve Tank

I'm aiming to renovate the pneumatics, fix all leaks have two sources of compressed air because I need it for tyres and suspension have an air supply for air suspension seats which need 90 to 120 psi regulation and adjustment for the air suspension. All clean and serviced. Progress so far. I've cut it back to the bare minimum  Found a cracked fitting The tank now holds pressure with negligible loss. Made an adapter to connect the handheld compressor to the air system. Next to do find the filter on the onboard compressor and clean or replace it. done take out the air tank clean it and paint it. done connect up a seat and test it out.  Add a regulator for the suspension and a pressure switch to control the compressor. ready to fit Add valves to use the airbags for leveling. almost ready
