Replacing the fuel filter

CD01N034 Clean the area around the filter head. Place a receptacle of a suitable capacity under the filter and remove the filter, using a filter wrench. Apply a fine film of oil or grease to the contact face of the new filter. NOTE: Do not fill the new filter with fuel before installing. Install the new filter. Turn the filter until the seal comes into contact with the filter head and turn an extra half turn by hand. IMPORTANT: Do not use a filter wrench to install the filter. Overtightening the filter can damage the seal and filter. NOTE: If the engine does not regain full power after replacing the filter, bleed the system.
