Tank inspection and replacement
For your protection, the CNG fuel tanks require visual inspection every
three years or 58 000 kilometers (36 000 miles) whichever comes first.
The purpose of the inspection is to check for exterior damage to the
tank wrap which would shorten its usable life span. This inspection
should only be done by qualified NGV Ford service technicians.
The expiration date for the tank replacement is stated on each tank label.
Coalescent fuel filter assembly
Your vehicle is equipped with a coalescent fuel filter assembly. Its
primary function is to remove contaminants; oil and water carryover
moisture from the fuel and trap it in the filter bowl.
The coalescent filter bowl should be drained every 192 000 kilometers
(120 000 miles). Perform fuel system depressurization procedure
(outlined in Service Manual) before disassembling the filter to avoid fuel
pressure regulator damage. The filter element (FG-985 on Econoline and
F-Series models; FG-976 on Crown Victoria models) and housing O-ring
seal should also be replaced every 192 000 km (120 000 miles) on
Econoline and F-series models and every 120 000 km (75 000 miles) on
Crown Victoria models.
Inspect and clean fuel fill valve filter
The fuel fill valve filter is located in the high-pressure fuel line.
Inspection and cleaning should only be done by a qualified
technician.
During the fueling process, natural gas is filtered before it enters the
CNG tanks. Debris filtered from the fuel will remain in the filter until it is
removed and cleaned. The fuel fill valve filter should be inspected and
cleaned annually. Fuel fill valve filter replacement is only required when
damage to the filter is visible.
Spark plugs
Replace spark plugs every 96 000 kilometers (60 000 miles) on Econoline
and F-series models and every 60 000 km (36 000 miles) on Crown
Victoria models. Use recommended nickel-plated platinum spark plugs
with the Motorcraft part number AWSF-22FM1 (or equivalent) on
Econoline and F-series models and spark plugs with the Motorcraft part
number AWSF-22FM (or equivalent) on Crown Victoria models.
