speeds below 1300 rpm. If one of these fuel lines groups is installed on an engine, a 2W5100 Fuel Lines Drain Group must also be installed. These fuel injection lines groups have a double wall (a tube within a tube) with a space between the tubes. If there is fuel leakage from the inner tube, the outer tube and the 2W5100 Fuel Lines Drain Group will direct the fuel leakage to a reservoir so the fuel can be removed from the engine compartment. These fuel injection lines groups should not be installed on engines that are equipped with a 3N8029 Governor Control Group (Air Activated). Any alarm or signal that is to be used with this switch must be purchased separately. The alarm or signal for fuel leakage and the 2N9768 Switch must both be connected into the alarm system for the ship, building, etc. Be sure to check the liquid level adjustment at which the 2N9768 Switch will activate to send a signal.
