Abstract
A firefighting apparatus on a small all-terrain utility vehicle has a U-shaped water tank closely spaced from the driver's cab. A reel for a high-pressure hose is mounted in the U of the water tank. A high-pressure engine driven pump is connected to the reel and a high-pressure hose through a water management system, which directs water from the water tank to the pump, and from the pump to the hose. The pump has a pressure valve which sets the engine idle when the high-pressure water nozzle is closed. A pressure unloader valve recirculates water from the pump outlet to the pump inlet when the nozzle is closed. A check valve is used between the water tank and a point where water recirculates to the pump. A prefilter is connected between the check valve and the water tank.
