For equivalent regional tools, refer to Special Tools.
- Remove the fuel injector rail cap (1).
- Relieve the fuel pressure. Use EN-34730-91 pressure tester (1).
Warning:
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.
Warning:
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.
