relay FORD E SERIES 2004 4.G Natural Gas Vehicle Supplement Manual

COMPRESSED NATURAL GAS (CNG) FUEL SYSTEM
Your vehicle is equipped with a dedicated compressed natural gas (CNG)
fuel system that is under high pressure.
Depending upon the application, the CNG fuel system is rated at a pressure
of 20,700 kPa (3,000 psi) at 21°C (70°F) or 24,800 kPa (3,600 psi) at
21°C (70°F). Refer to the label on the fuel filler door to determine the
fuel system pressure rating.
Use caution when servicing or maintaining any of the components of the
CNG fuel system.
Service to high-pressure fuel system components must be
conducted only at qualified dealerships by qualified technicians.
Failure to do so may cause damage to components or cause bodily
harm.
On F-150 Heritage natural gas vehicles,do not modify or replace the
bed with any non-OEM components. Should the bed need to be removed
for service or replacement, it should be done by a qualified dealership
using qualified technicians. Do not sit, stand or place heavy loads on the
in-bed or in-vehicle tank covers. Any bed cap added to this vehicle must
be well ventilated. Failure to provide adequate ventilation could result in
gas vapor build up over time potentially resulting in a combustible
mixture.
