ENGINE MAINTENANCE<br />
Please follow these recommendations when you are<br />
changing your fuel filters or strainer elements. Your vehicle's<br />
engine will run better and last longer if you do. See<br />
the engine manufacturer's recommendations for proper<br />
water and micron requirements.<br />
Installing Fuel Filters<br />
When removing filters, cover any electrical equipment and<br />
wiring that might get soaked with fuel. Diesel fuel may permanently<br />
damage electrical insulation.<br />
When installing spin–on (throwaway) filters:<br />
1. Prefill filter with fuel.<br />
2. Moisten gasket with diesel fuel.<br />
3. Hand tighten them only 1/2 to 2/3 turn after gasket<br />
contact. Mechanical tightening of these filters may<br />
distort or crack the filter head.<br />
• When replacing a fuel filter element, do not use a substitute.<br />
Install only filter elements designed for fuel filtration.<br />
First clean and inspect the shell. Then insert<br />
the new element and fill the container at least 2/3 full<br />
of clean fuel before installing the shell<br />
PREVENTIVE MAINTENANCE<br />
NOTE: To expel air from density-type strainer<br />
elements, soak them in clean fuel before installing<br />
them.<br />
• Throw away old gaskets. Replace them with new<br />
ones to ensure a positive seal.<br />
• Position the shell and gasket properly. Then tighten<br />
the cover nut or bolt just enough to prevent fuel leakage.<br />
• After starting the engine, check for leaks around the<br />
filter.<br />
Filter Draining<br />
Check fuel filter/water separator daily. Check with engine<br />
OFF. Depending on the fuel storage facility, more frequent<br />
draining may be required.<br />
1. Open drain valve (by hand only): turn valve screw<br />
counter-clockwise approximately 1 1/2 to 2 turns until<br />
draining occurs. Drain filter sump of water until clear<br />
fuel is visible.<br />
If entrapped water exceeds sump volume, you can either:<br />
