  3. Remove and discard the fuel meter body seal.
    4. CAUTION: Do not use any solvent that contains Methyl Ethyl Ketone (MEK). This solvent may damage fuel system components.
  4. Prior to removal, clean the fuel meter body with a spray type engine cleaner, such as GM X-30A, or equivalent, if necessary. Follow the package instructions. Do not soak the fuel meter body in liquid cleaning solvent.
    5. NOTE: When removing the injectors, mark the injectors with tape and their corresponding cylinder number in order to ensure correct injector placement upon installation.
  5. Lightly pull on the fuel injector tube, and using a small pocket screwdriver, remove the fuel injector from the lower intake manifold bore.
    6. NOTE: During the removal of the fuel meter body, the retainers that hold the injectors into the intake manifold may become worn. This is OK. Upon installation of the intake manifold, the injectors will be held fully seated, thus keeping them from backing out of the lower intake manifold.
  6. Remove the other 5 fuel injectors from the lower intake manifold bores.
    7. CAUTION: Cover the injector sockets in order to prevent dirt and other contaminants from entering the open fuel passages.
  7. Remove the fuel meter body (1) from the vehicle.
