3. Replace the fuel filter every 100 hours or OC. Check for fuel contamination by cutting the used filter in half and
inspecting the inlet side of the filter element. If the element is contaminated, inspect and clean the pre-filter in the fuel
shut-off valve/filter assembly (see note 4 below). When installing the new filter, be sure to replace the two crush
washers (12MM part no. E25-4740, 14MM part no. E25-4750) and note proper flow direction.
4. After the first 25 hours of operation, check the pre-filter for any particles or debris that may have washed out of the fuel
tanks. Clean as necessary. Every 500 hours, disassemble, clean and inspect the fuel shut-off valve/filter assembly.
Replace O-rings as necessary. Refer to the Engine Manual for complete procedures.
5. If the needle on the fuel gauge stays above the full mark when the tank is not full, check the following: water in fuel
tank, meter not grounded properly, sender wire is touching negative terminal or wiring, center rod of the sender is
touching the outside tube, or sender is not calibrated. If the needle stays at empty, check the following: no power to
sender, no power to gauge, sender not connected to gauge. If the needle fluctuates, check for loose or corroded
wiring connections.
