FUEL SYSTEM PRESSURIZATION When it comes to safety and outboards, the condition of the fuel system is of the utmost importance. The system must be checked for signs of damage or leakage with every use and checked, especially carefully when portions of the system have been opened for service. The best method to check the fuel system is to visually inspect the lines, hoses and fittings once the system has been properly pressurized. Furthermore, FFI motors are equipped with two inter-related fuel circuits, a low pressure circuit that is similar to the circuit that feeds carburetors on other motors and a high-pressure circuit that feeds the fuel injection system. As its name implies, the high-pressure circuit contains fuel under pressure that, if given a chance, will spray from a damaged/loose hose or fitting. When servicing components of the high pressure system, the fuel pressure must first be relieved in a safe and controlled manner to help avoid the potential explosive and dangerous conditions that would result from simply opening a fitting and allowing fuel to spray uncontrolled into the work area.
CARBURETED MODELS Carbureted engines covered by this manual are equipped only with a low-pressure fuel system, making pressure release before service a non-issue. But, even a low-pressure fuel system should be checked following repairs to make sure that no leaks are present. Only by checking a fuel system under normal operating pressures can you be sure of the system's integrity. Carbureted engines should be equipped with a fuel primer bulb mounted inline between the fuel tank and engine. The bulb can be used to pressurize that portion of the fuel system. Squeeze the bulb until it and the fuel lines feel firm with gasoline. At this point check all fittings between the tank and motor for signs of leakage and correct, as necessary. Once fuel reaches the engine it is the job of the fuel pump to distribute it to the carburetors. On pre-mix 2-stroke motors the fuel is pumped directly from the pump to the carburetor. When equipped with the VRO2 system (as are most Evinrude/Johnson V-motors), VRO pump (consisting of a fuel and oil pump, as well as a fuel/oil-mixing unit) is responsible for feeding a fuel/oil mixture to the carburetors.
