Hello, I hope someone can help me, I'm having a problem with my 2004 jaguar xj8, the airsuspension is very low, two of the hoses from the solenoid block are leaking, I'm trying to find a diagram to find the size of the hose to repair and cant find it online. It looks like is the smallest size and should be for the back but im not sure, the colors are the red and blue. I call Guandin to order a repair kit but they are not sure if it will work for me. Can I get some help please, thank you.

OK, here is what you need: the small line nut is 4mm and the large line is 6mm. The nut has an O-Ring on it and there is also an "olive" or "cutter" right under the nut.

The leak will be coming from the end of the air line that goes into the solenoid block or strut. Usually it is the O-Ring that is the culprit. (Results from over tightening) lines are to be only tightened to 5 Nm.

Here are the part numbers: (just ordered some "spares" from SNG Barrett)

* C2C9931 - End connector (available in 6mm and 4mm) - awaiting SNG Barrett to confirm this part number covers both the 6mm and 4mm sizes

* C2C9930 - In Line Connector (4mm size)

*C2C9932 - In Line Connector (6mm size)

Hope this helps...

 

Thank you!! I will check that page. Two of the hoses have holes on it, the one that comes out the red color line and the blue one... I think is the 4mm because they are the small hose but on the repair kid they only have one size hose 6mm. I will check the webpage you send me thank you again

 

To add - once I actually receive these parts (been waiting a few weeks now) I will post pictures of the parts w/ numbers for future reference as these parts/part numbers were a PITA to track down... (Thanks SNG Barrett for helping with this...)

 

If the hole in the tube is close enough to the connector and you have enough slack in the tube to accommodate - just slice the tube straight with a razor blade and reconnect it. Otherwise - you will need the "in-line" connector to repair the hole in the air line.

In my instance - the previous owner's mechanic disconnected the two front air tubes all together (one line - driver's side was damaged at the connector) and proceeded to connect regular 6mm valve stems to fill up the struts w/ compressed air. (I promise a thread w/ pics of this set up - it's quite ingenious if it was completed on the back end) The problem was the air lines from the solenoid block to the front struts were not capped off at the block in trunk so the compressor would "time out" due to the open air lines up front. Upon taking ownership - I found some spare end connectors and olives, cut the damaged part of the air tube straight w/ a razor and massaged it a bit w/ my torch - which you have to hold it far enough to massage it or... your tube will be up in smoke... literally... (to get it straight into the strut fitting) and reconnected w/ success - no more 'air suspension" fault and neither line is leaking (checked w/ thick soapy water solution) its been 2 days now and the front end is firmly in place.

I am waiting for some warm/dry weather to install the bagpipingandy ring fix as a preventative measure - considering the excessive running time of the compressor w/ those 2 open air lines.

 

Spoke to Mike Glover at SNG Barrett (these guys are really helpful!) and he confirmed the following parts numbers for the air tube - end connectors:

End Connector - 4 mm size (C2C9930)

End Connector - 6 mm size (C2C9931)

My order with these parts just shipped out today and again, will post pics upon arrival (for future reference)

Thanks - Anthony

 

Here are the pictures of the parts (as promised)

* C2C9931 - 6mm end connector.
* C2C9930 - 4mm end connector
* C2C9932 - 6mm inline connector (this part repairs a broken air line) - has end connectors, O-Rings and cutters on both ends - (they have this for the 4mm alr line also)

 

Very nice! Thanx for posting this!

 

Thank you for your help, I will order the inline connectors today, I hope it's not hard to install... I will heat the line then will install the inline connector I will let you know if I did it right thank you again to all for all the help

 

If the hole is in the straight part of the line no need to heat it. Just cut the section containing the hole straight with a razor - then insert both ends into the inline connector. Remember - tighten each nut only to 5Nm - no tighter.

 

Yes, is in the straight part of the line... do i need a special tool to tight to 5Nm? I have been asking myself how the inline connector will stay on the line with all the air pressure?

 

The metal cutter and o-ring keeps the air line snug in the fitting. 5Nm is about "hand tight" - any tighter and you risk splitting of flattening the O-Ring, which is the #1 cause of air leaks at the connectors.

Good Luck.
