Emergency air up instructions

According to the LR D3 manual, you are not meant to reuse the Voss fittings and should replace each time you disconnect. So if replacing, just convert all to push fit.

Then you have almost unlimited options for how to plumb up the emergency set up - and all without cutting into any existing piping.

For connecting to the existing line - once the Voss fitting is removed from the pipe, you could just use a push fit to push fit 6mm pipe coupler which can be either straight or elbows depending on where the new piping is being routed.

So use the LF3699 fitting for the air bags and air valves (right angle to change direction for the extension pipe), and then either the LF3602 or LF3606 6mm pipe to pipe couplers depending on if you need a change in direction or not as per the GOE instructions.

I know the GOE set up just reused the Voss fittings, but I find it interesting that LR say these should be replaced anyway.

The Gordon EAS system just puts an extra "loop" into the line to each air bag. If You have an issue then you disconnect the loop and pump air directly into each bag individually. In other words the other side of the loop which eventually goes back to the car compressor is bypassed. If you just put one external pump up section near the existing car compressor, you may need to bypass the compressor completely. I say this because lets just say the compressor blows a ring, then unless you can isolate it completely, air will back flow into the compressor and you will be loosing air. Pulling out a fuse wont work in this case. I dont know if putting a one way valve would work as I dont know how the air system we have gets rid of air to deflate the air bags. I think Gordons system whilst it introduces about 5 metres of extra hose to the system works the best. Its simple, it works, and so far I have not heard anybody complain it does not work or has failed.

Good points dirvine. This thread is now about how to reverse engineer the GOE kit given you can no longer buy it. Plus by all accounts the original kit sold with about a 200% mark up.

A similar discussion took place back when Gordon was first developing the kit.

No, you can safely remove/replace the compressor assembly without losing any air pressure elsewhere in the system. From the manual: "The front and rear valve blocks and the reservoir valve block are normally closed when de-energized, preventing air pressure in the air springs and the reservoir escaping when the unit is disconnected." This is a really neat feature and must be considered when looking at an emergency supply (other than Gordon's which you describe well).
What also must be considered is that the air reservoir only has one one line for input and output. If the reservoir had a separate input port (like the series and P38 ones did) then keeping it pressurised to 244psi would be simply a matter of connecting a suitable compressor feed to the input port (via a non-return valve). You would then clear the fault codes pertaining to the failed compressor and the EAS computer would be none the wiser as it would not need to send a signal to it to operate as there would always be enough pressure in the rest of the system.
There will be a way to do this, I just haven't figured it out yet. But I agree that Gordon's is a clever and simple system that not only covers all EAS system failures, it also covers a damaged airbag as the car will still be driveable (well, slowly moveable) on three airbags. Probably.

Can always mount a second air tank on the opposite side with a few mods. Been done before.

I consider the 200% mark up part of the R & D Gordon went into to resource, make up the kit, packaging and instructions. In the past In have made products for retail outlets and my mark up was well over 200%. Closer to 350%!!. If we worry about mark up just buy chinese product. Mass Volume, little quality control but lower profit margin per unit. I know which I would rather buy especially now with all the who ha over imports from Asia!!!

Unfortunately GOE is no longer in business and there is no other kit available, so hopefully with the collaboration of the brilliant AULRO members, we will be able to reverse engineer this kit and provide details for anyone to make it up themselves for around $100.

Small kit as follows

Is carried and only fitted when needed which I liked. Is quoted as needing an air compressor capable of 80 psi and needing 30-60 minutes to fit.

Car can be completely returned to stock after use.
