CHECK AND DRAIN WATER 

Check the water separator bowl. Only drain when water is visible or when notified by the ‘water in fuel’ code and at every fuel filter replacement. Install an extra hose then loosen the drain. 

REMOVE THE OLD FILTER 

Service only when required otherwise replace every 1,000 hours or annually. Disconnect the electrical connector and remove the separator bowl. Remove the filter. 

INSTALL A NEW FILTER 

Do not pre-fill a new filter with fuel. Lubricate the new O-rings. Install the separator bowl before installing onto the filter housing. Connect the electrical. Perform any final cleanup. The fuel system will need to be primed with fuel and air removed from the system.  

REMOVE THE OLD FILTER 

Clean the pre-filter and area. Move the hose clamps off. Remove each fuel hose and loosen the filter clamp. Note the orientation of the arrow on the pre-filter before removing and discarding it. 

INSTALL A NEW PRE-FILTER 

Install the new pre-filter with the arrow facing the correct direction. Install hoses and move the clamps back to the correct position. Remove the hose pliers. 

PRIME AND REMOVE AIR  

Any time a fuel filter is replaced, the pre-filter will need to be primed and air removed from the system. 

REPLACING A BREATHER CAP 

Your machine may also have a fuel tank vent or breather cap that vents excess pressure. Replace with a new genuine Bobcat part.
