OPERATION
The diesel engine has a water in fuel warning system allowing the user to guard against water in fuel, which is very critical to diesel engines.
The fuel tank is equipped with a filter which screens out the water and lets it lay in the bottom of the tank below the fuel pickup. When the water
level reaches a point where it could be drawn into the system, a warning light flashes in the cab. A siphoning system starting at the tank and going
to the rear spring hanger on some models permits the user to attach a hose at the shut-off and siphon out the water.
