Air Accumulator tanks - Jesse - 06-20-2025

Took the rig out to the Hoodu mountains and developed a nasty air leak under the cockpit, figured it was the ride hight valve - still produced just enough air pressure to get back home. Drove the coach up a make shift ramp and discovered a small pin point hole on the bottom of the drive side air accumulator tank. I manually empty the air tanks about 4xs a year to drain the water which I figured is fine since it's not humid up here in Alaska. I guess I was wrong! I did a quick handyman fix of using a self taper screw with a rubber gasket and gasket sealer into the hole of the tank after cleaning it well. I did the same fix on a hot water tank on a Country Coach numerous years back with good results. Going to let the sealer cure a day before testing. Question for you all - how in the heck do you replace these tanks if needed? They are fully encased in a steel frame of the suspension. On my old country coach they were easy to get off with just 2 straps each. Thanks everyone and happy camping!

Ouch, you can’t get those tanks out without cutting them up OR cutting a section of the frame. Newell’s solution has been to mount a remote tank in one of the bays.

Ha ha, that's my backup plan if I can't find a solution to seal the hole. Seems like a very poor design to have them encased in the frame...very strange. Thanks for the confirmation on a path forward, Richard. Even if I get a good seal on this tank I am going to start researching a replacment tank since if 1 hole developed another is sure to happen in the worst location.
