ITEMS NEEDED

Be sure to have a few items ready:

• Safety glasses
• Work gloves
• A genuine Bobcat fuel filter (part number 7336334), available at your dealer, or online.
• A genuine Bobcat pre-filter (part number 7348032), available at your dealer, or online.

GET STARTED

Check the operation and maintenance manual before performing any maintenance work, and make sure the engine is cool before starting service

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 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.

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.

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.
