Fuel System Pressure Test
WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component.
Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING: Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any
fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in
