Air line pneumatic burst (leaking air line)

[GypsyTurtle]

1989 Country Coach Concept
Gillig chassis

Left rear compartment that houses the electrical shore power hookups has an Accessory Air Line end... A few feet in from that the 3/8" white line has burst so I can't air up the suspension, operate the throttle or transmission...
HHS line is old and has swelled slightly for a ways beyond the burst point so I can't easily fir the brass compression fittings over he line.

I'm wondering if someone has diagrams so I can figure out where the line goes as it disappears toward the front of the chassis. I see 2 similar looking lines entering the HWH bay under the driver's seat...

Any ideas?
I'm stuck at a friend's house so it's not terrible.. Plus he's an awesome grill-cook...but I'd like to replace or cap this line temporarily so I can drive home 65 miles... Towing doesn't work since the suspension won't air up.

Thanks for reading!

How about taking a dowel of the I.D. of the hose, sand or shave it if too big, insert in the broken line and put a hose clamp on to hold in place. It should get you home then you can trace and replace the whole line.

When they installed my toad system they hit an air line and they installed a quick fitting. They just cut the line and it pushes together so I went up to Napa and got a spare. I got one each 1/4 and 3/8" line size if I remember right.

You will need to cut it to fix it anyway so with a loper or shear cut a short piece with the damage out and tske it to a nspa or truck brake service location.

These things happen and simple double coupler will do the trick.

If damage is more then piece of hose and 2 couplers.

If that air line was only feeding an outlet and you don't need it at the moment, use a pair of Vyce-grips to crush the airline blocked. Not recommended as a permanent fix but ...

Another way is to remove the accessory outlet to where you can cut the air line in a good section and reconnect the outlet if the fittings can be reused.
