Dear Caterpillar Product Owner:
The spin-on fuel filter base needs to be inspected on the products listed below. The stud height may be incorrect which can cause the spin-on fuel filter to blow off of the filter base and result in a fuel leakage hazard. You will not be charged for the service performed.
Contact your local Caterpillar dealer immediately to schedule this service. The dealer will advise you of the time required to complete this service. Please refer the dealer to their Service Letter dated November 23, 2000 when scheduling this service.
We regret the inconvenience this may cause you, but urge you to have this service performed for your added safety and satisfaction.
