Hi Guys. I now have 3 6mm joints to use, whitch ones would you recommend to use on putting my air lines right as I have just looked at the ends the go into the EAS block and they look worn out, so answers please Guys. No 1 the brass type or No 2 the full black one or No 3 the one with the blue tips.

If brass one is a compression fitting with olives not much good on plastic unless you sleeve the inner bore. For me the one on the right is best. Small amount of silicone grease around the pipe ends.

What did you do on the ends of the pipes, I was told to run them though a pencil sharper before fitting them is that right.

Yes. Just to take sharp edges off so they don't damage the o-rings as you push them in. A bit of wet and dry to smooth them off wouldn't hurt.

Well the pipe ends looked like this, picture 1, so cut and added the joints with new pipe and raised the suspension to full height, 2nd picture is of the joints, 3rd picture is the car after 1 hour gone down again. I know it not the old pipe works as I had them on the Schrader valves for 5 days and it never dropped. So back to the drawing board to try and figure this out.

I guess it could be the other pipes that you havent repaired?
Are you sure your valve block is ok?

Completely restored the whole of the valve block with all new seals and push in seats that the pipe goes into,also after pumping up the suspension sprayed water on the EAS block to check for any leaks and nothing,puzzled.

Soapy water since you replaced the two pipe ends?

Have you tried T-ing in a pressure guage on the tank line and see if the pressure drops overnight? I had a spare guage but I think I gave it to Gorsky.

+1
Seems like the leak could be in the feed to the tank
How is your exhaust?

J L Carr · Jul 28, 2020

If it's leaking from the feed tank line then why is it always the backend that drops, what's the exhaust go to do with the suspension apart from being to close so it would melt a pipe.

I used a proper cutter

I bought one of these when I started watercooling PCs.

Amazon product

Works a treat on EAS lines.

Main air lines to tank and rear bags go over back axle.
Slightest exhaust leak will melt them and is a pig to find the leak

How did you cut the pipes?

Yes but I had all air line blown up on my Schrader valves for 5 days and there was no drop in the ride heights, as I was waiting for a full set of seals from Rimmer Brother's,so I know it's not the main air bag lines. If the feeder pipe is leaking would that make only the back to drop, I would have thought all would drop.,
