Fuel Delivery and Air Induction: Service and Repair

REMOVAL PROCEDURE

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.
^ 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.
^ Always wear safety goggles when working with fuel in order to protect the eyes from fuel splash.

NOTE: Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and passages.

IMPORTANT:
^ Always replace the fuel limiter vent valve O-ring when reinstalling the fuel limiter vent valve.
^ Always maintain cleanliness when servicing fuel system components.
