Disco 3 Air suspension broken hoses

[timdo1]

Hello All,

I replaced a Hitachi compressor with an ebay one. That was the first mistake, that blew in 5 days. So this afternoon I picked up a replacement from British Auto parts and came home to install. First issue, the hoses wont come out. I managed to get them off but discovered in the process that one of the hoses has a very large hole in it from where it has worn against something. So now I need to repair the air line. Where can I get the parts quickly, I will need a couple of connectors and some air line. Any ideas? I really need the car going again quickly if thats possible.

Any hydraulic fitting shop like Pirtek has the air fittings to join. Ring first.

Hoses are a push fit. To get them out, you need to push the collar of the fitting down or into the housing whilst pulling on the hose at the same time. If you don't, the cutting ring inside the fitting will bite deeper and deeper into the hose until both fail. If stuck due to grime, a bit of compressed air around the outside may help. A bit of wd40 also helps, just make sure to blow it all out with compressed air.

I've use Fittings Express at Brendale before. They have all of the 6mm parts and hose you need. Wherever you get your fittings from, make sure you get fittings rated for 2MPa. There are plenty of fittings available rated at 1Mpa, 150 PSI, or not even rated. The air suspension system can exceed 250PSI, so you need appropriately rated hoses and fittings.

Thanks everyone,

Got what I needed from Pirtek. Installed with a new Hitachi pump and everything works again. Still slow to raise. I ordered valve block rebuild kit so I'll do them when that arrives. I also have a faulty module I think. That arrived tonight so that will go in shortly.

Couldnt get the hoses out of the cheap chinese compressor, clearly not a very good product.

Heres the broken hose. A large hole I would think. 178443

When you do that, make sure you blow through all the gallery lines, and pressure cycle the reservoir a couple of times (pump it up with an air-gun and let it blow down) to blow out as much silica dust as you can. Don't be like me, and make sure you wear a decent mask when you do it. Amazing how much silica dust comes out of the system.

I will do,

Was wondering if I had to do anything special. Its still not here but I'm not shocked by that considering our brave new world.

Thanks for the idea.
