My 75 Glenbrook (alias Brutus) seemed happy with its new mufflers and new Remflex manifold gaskets ($671.97 including tax not not counting the gaskets). It sounded like a million bucks driving home from the muffler shop - instead of an old John Deere (no offense to John Deere lovers). You'd think the machine would be happy - but no - now it's s unhappy about something else and showing it's displeasure by leaking down on the drivers side on hold position when i wasn't looking. Fortunately I outsmarted it sometime back and installed Jim B's shutoff system and can easily isolate the bag which continues to hold up nicely when isolated from the system. I pulled out the shutoff valves (J.R. Slaten) to the generous inch or so that the spare hose length would allow ) and there does not seem to be a leak there so I'm thinking there must be a leak in the line somewhere. My lines are a patchwork of faded colors with splices here and there (some of which I have made myself).
My question is what was the original color of the hold,raise & lower line from the valves to the bag on the drivers side. If I replace the entire line I might as well use the original color.

Bob,
Grey to the bag, red and purple to the height control valve for the drivers side. This is on page 4-31 in X7525 maintenance manual. You have a '75 so this is for the power level system.

Even though all the lines are black they are not difficult to trace, when I
replaced mine a few years ago I used all black.
I would recommend you install the shutoff valve at the bag first, if that holds
then your leak is between the shutoff valve and the pump, but some good leak
testing soap, it shouldn't be too hard to find.

what the lines should be coloured?
a PO replaced every line on my air system with...Black. every one is black. I
don't look forward to the day I will need to trace one of the lines. but for now
(knock on wood) they seem to be working well except that the drivers side bag
seems to leak down :p
and I have the shut offs as well... one is in the drawer in the galley the other
has been installed. might want to move that up the to-do list.

Once you replace everything that is attached to something else. It will all be

Thanks, Ken. I have printed that page out!
I have many leaks in my system.
Thanks to a P.O., my coach came with Schraeder
valves and then Sully's installation of his new
airbag system at Shawnee at least has my coach
not squatting while at rest!

If you have shut off valves, and it is normal for you to travel with them
closed, then you have lots of company. If your sullybags maintain ride
height at less than 100 psi, you are a prime candidate for the wireless
air control system. Throw away that old style compressor, those many feet
of leaking lines and rusty air tanks and manual valves. The wireless system
is dynamic, and responds to changes in air pressure as slight as 3 psi.
Holding tank draining is a snap as is returning to ride height. Site
leveling is also simple.

I have never seen anywhere near 100 psi in the Sullybilt system other than in testing. Usual operation pressures will be around 60 psi and below with typical coach loading.

Todd, I know that normally, your system carries pressures lower than 100
psi. But the Bovee Wireless system's upper limit pressure is 100 psi, so it
will NOT work at higher pressures unless bag extenders are used which will
lower the ride height static pressures to under that figure.

I hear you Jim. I look at the low operation pressures of the Sullybilt like an accidental benefit of the retrofit.
Invest < $700 in the Sullybilt system
Keep one orig bag for spare
Sell second bag $100?
Install wireless system
Sell old compressor assy $75-100?
Take the air suspension system off your to do/ worry list. Priceless
