The problem
The pressure relief valve was omitted in the air tank. The air tank is the reservoir for the air suspension and is not brake related. Without the pressure relief valve, there is no back-up system to limit air pressure in the air suspension system.
The risk
Lack of a back-up system to limit air pressure build upcan cause excessive pressure in the air tank and can cause the tank to rupture.This can result in personal injury to anyone in the vicinity.
The fix
INSTALL A PRESSURE RELIEF VALVE IN THE AIR TANK.
