Adapter Installation Instructions


Caution: Never work on a hot engine!

We recommend disconnecting the battery

For ease of access, the passenger-side front fender well may need to be removed

1. Disconnect the factory fuel filter heater wire on top of the factory fuel filter head

2. Unplug the Water in the Filter sensor. This can be saved in case you may want to go back

to the stock setup later. Removing will not trigger a check engine light.

3. Remove the 2 bolts that attach the factory fuel filter head to the mounting bracket.

Remove the factory fuel filter. Note: this may contain fuel that may spill out. Make sure to remove the O-ring seal with the filter.

4. Once out make sure that the O-rings for the filter adapter and CAT filter are lubricated with no dry spots. Thread the Jandy Diesel Fuel Filter Adapter onto the factory filter head and hand tighten and reconnect the factory fuel filter heater wire.

5. Thread the CAT filter onto the adapter making sure that there are no dry spots on the O-ring and hand tighten.

6. Install the assembled Jandy Diesel fuel filter adapter and CAT filter onto the engine. Tighten the adapter and filter hand tight.

7. Replace the plastic stock air bleeder screw with the Jandy Diesel aluminum bleeder screw. Fully tighten the new bleeder screw.

8. Prime the filter by pushing the primer pump 4-5 times and then loosen the screw to bleed off air. You may have to repeat this a few times until all the air is completely out of the system. Tighten the Jandy Diesel air bleeder screw and start your engine checking for any leaks.

Congratulate yourself on a job well done!
