- 1. Change the fuel strainer and fuel filter elements.
- 2. Drain water and sediment from fuel tank.
Changing The Fuel Filter And Fuel Strainer Elements
The fuel filter and fuel strainer have spin-on type elements (cartridges). To replace them:
- 1. Unscrew the cartridge and discard it.
DO NOT SMOKE OR HAVE AN OPEN FLAME WHILE CHANGING THE FUEL FILTER AND STRAINER. DIESEL FUEL IS VOLATILE AND COULD IGNITE OR EXPLODE, CAUSING SERIOUS BURNS AND INJURIES FROM FLYING OBJECTS.
- 2. Fill a new replacement cartridge about 2/3 full with clean fuel oil. Coat the gasket lightly with clean fuel oil.
- 3. Screw the cartridge onto the threaded post until the gasket contacts the head, then tighten the cartridge about 2/3 turn more.
- 4. Start the engine and check for leaks.
Draining Water And Sediment From The Fuel Tank
DO NOT SMOKE OR HAVE AN OPEN FLAME WHILE DRAINING FUEL. DIESEL FUEL IS VOLATILE AND COULD IGNITE OR EXPLODE, CAUSING SERIOUS BURNS AND INJURIES FROM FLYING OBJECTS.
- 1. Close the valve in the fuel supply line at the bottom of the fuel tank.
- 2. Remove the line from the valve and quickly cap the line or hold a finger on the end of the line to stop the flow of fuel.
- 3. Open the valve and allow the fuel to drain until free of water and sediment, close the valve, reinstall the line and then open the valve.
- 4. Check for leaks.
If the tank shows signs of excessive water or sediment, drain the tank as described above, remove the cap and attached shutoff valve from the bottom of the tank and allow the tank to completely drain. Replace the cap, reconnect the supply line and refill the tank with clean fresh fuel.
