Caution: Gasoline or gasoline vapors are highly flammable. A fire could occur
if an ignition source is present. Never drain or store gasoline or diesel
fuel in an open container, due to the possibility of fire or explosion. Have
a dry chemical (Class B) fire extinguisher nearby.
Caution: Relieve the fuel system pressure before servicing fuel system components
in order to reduce the risk of fire and personal injury.
After relieving the system pressure, a small amount of fuel may be released
when servicing the fuel lines or connections. In order to reduce the chance
of personal injury, cover the regulator and the fuel line fittings with a
shop towel before disconnecting. This will catch any fuel that may leak out.
Place the towel in an approved container when the disconnection is complete.
Caution: Refer to Safety Glasses Caution in the Preface section.
