Compressed Natural Gas

DO NOT modify system configuration or components or replace components with components not specifically designed for use with natural gas. Manufacturer has specifically designed materials and precisely calibrated each component and system configuration for efficient operation. Use of different parts or materials can produce an untested configuration that can result in fire or personal injury or cause engine damage.

It is important that bi-fuel vehicles be properly maintained by bi-fuel trained personnel. If a concern occurs, it is important that correctly trained personnel diagnose the cause. If a concern relates to fuel system, correct part replacement is imperative to keep vehicle operating at normal performance. Bi-fuel components and gasoline specific components are not interchangeable. If vehicle is not serviced in accordance with bi-fuel service procedures, damage can occur and vehicle warranty may be invalidated.

Fuel supply lines are always pressurized. When servicing fuel-related components, DO NOT smoke or carry lighted tobacco or an open flame of any type. Flammable mixtures may be present and can ignite, resulting in personal injury. The natural gas fuel system is always pressurized to 95 psi (655 kPa) downstream of fuel pressure regulator and up to 3600 psi (24,821 kPa) upstream of fuel pressure regulator. Use care when servicing fuel system, or personal injury can occur. The natural gas fuel supply manifold is pressurized to 95 psi (655 kPa). Fuel pressure must be relieved prior to any fuel system service. Fuel system pressure must be relieved before any component can be removed. Fuel tanks must be evacuated prior to tank removal. Removal of components without pressure relief or tank evacuation can cause natural gas to escape into the air and cause injury or death. Observe all warnings when performing the natural gas leak test. See LEAK TEST - ALL BI-FUEL VEHICLES  under FUEL SYSTEMS.
