We have a GL1800 2003 Motortrike Spyder conversion, which we are having an ongoing problem with air suspension loosing air. We have tested all the joints etc and can’t locate any leaks. The air bags were replaced 3yrs ago.

We would like to replace the air line and fittings, however as we are located in Scotland, we are having trouble finding the size needed.

Could someone provide us with the correct size of airline and push fitting size?

Has anyone installed a new compressor with larger airline?

Any advice very much appreciated.

Thanks
