collected water. The dual canister configuration provides additional filtering capacity. The fuel flows through

the adaptor to a large combination fuel-water separator/filter and back to the fuel filter for final filtering.

g. High Pressure Fuel Lines. The high pressure

fuel lines are designed and manufactured to deliver

fuel at injection pressure to the injectors. The high

pressure pulses will cause the lines to expand and

contract during the injection cycle. The high

pressure fuel lines are clamped and routed so that

they do not contact each other or any other

components.

h. Fuel Drain Manifold. The fuel system is designed to use fuel to cool and lubricate the injection pump

and injectors. Fuel is continually vented from the injection pump and a small amount of fuel leaks by the

injector needle valve stem during injection. This fuel is returned to the supply tank by the fuel drain

manifold.
