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 prefill a new filter with fuel. Lubricate the new Orings. 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 prefilter and area. Move the hose clamps off. Remove each fuel hose and loosen the filter clamp. Note the orientation of the arrow on the prefilter before removing and discarding it.

INSTALL A NEW PREFILTER
Install the new prefilter 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 prefilter 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.
