It has been run continuously at times due to air leaks and it lives in the rusty wet rear compartment, yet still runs strong. I want to replace both tanks with a new tank and all new hose and fittings. I'm just wondering why the two tanks and if the little one served a specific purpose? Where have others bought they new tanks and lines?
This appears to be the same tank used in my coach. Mine is secured by a U bolt around the tank and through the forward wall of the compartment. The band of rust around the center of your tank looks like evidence of a U bolt mount. It is the only tank in the system and with the new compressor I installed a couple of years ago the system works beautifully. The tank fills from empty to full pressure in less then 2 minutes and the bags hold the rear of the coach at travel height parked for nearly 2 weeks. By the way with the delay in the height control valve the compressor rarely cycles going down the highway. I would guess the tank is about one gallon capacity.
Good luck, Dan
