Main Fuel Filter Element Changing
Main Fuel Filter Element Changing - EuroV MBE900
- Open the vehicle fuel tank filler cap to release pressure in the fuel system. Replace and tighten the cap.
- Clean the outside of the fuel filter housing. See figure below.
- Using a 36-mm socket wrench insert, unscrew the cap on the fuel filter and remove it, along with the filter element. Pull both the cap and the filter element a short distance out of the filter housing. See figure below. Allow the fuel to drain off the filter into the housing.
- Remove the cap with the filter element. To release the filter element, twist the lower edge of the filter element to one side.
- Pull the dirt collector out of the filter housing using the tabs on either side.
- Clean the cap and the dirt collector.
- Replace the O-ring.
- Install the new filter element in the cap. Make sure the filter element is securely in place.
- Insert the dirt collector into the filter housing. Make sure the dirt collector is positioned properly in the filter housing.
- Screw on the cap with the filter element. Tighten the cap 25 N·m (18 lb·ft).
- To bleed the fuel system, make sure that all high-pressure lines have been tightened to 25 N·m (18 lb·ft) and all banjo bolts to 40 N·m (30 lb·ft).
- If equipped with a hand pump on the fuel/water separator, work the hand pump 50 times.
- Crank the engine for 30 seconds at a time, but no longer . Before cranking the engine again, wait at least two minutes. The engine should start within four 30-second attempts.
- Start the engine. Check the fuel filter for leaks.
Notice: To prevent damage to the filter housing, do not
allow dirt to get into the filter housing. Do not empty the dirt collector
into the filter case.
Notice: Correct torque on the high pressure lines is critical. Incorrect
torques could result in leaks or lack of power due to restricted fuel
flow.
