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 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
See instructions on fuel container for inspection and service life.
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 48,000 kilometers
(30,000 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 E-Series and F-Series
models; FG-976 on Crown Victoria models) and housing O-ring seal
should also be replaced every 48,000 km (30,000 miles).
Inspect and clean fuel fill valve filter
On Crown Victoria and F-Series models, the fuel fill valve filter is
located in the high-pressure fuel line. Inspection and cleaning
should only be done by a qualified technician.
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 E-Series
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
E-Series and F-series models and spark plugs with the Motorcraft part
number AWSF-22FM (or equivalent) on Crown Victoria models.
