Fuel Meter Body: Service and Repair

FUEL METER BODY ASSEMBLY REPLACEMENT

REMOVAL PROCEDURE
An 8-digit part identification number is on a mylar label affixed to the fuel meter body assembly. Refer to this number if servicing or part replacement is required.

1. Disconnect the negative battery cable.

CAUTION: Refer to Battery Disconnect Caution in Service Precautions.

2. Relieve the fuel system pressure. Refer to Fuel Pressure Relief Procedure.
3. Remove the upper intake manifold assembly.




4. Before removal, clean the fuel meter body assembly with a spray type engine cleaner, GM X-30A or the equivalent, if necessary. Follow the package instructions. DO NOT soak fuel meter body assemblies in liquid cleaning solvent.

NOTE: Do not use any solvent that contains Methyl Ethyl Ketone (MEK). This solvent may damage fuel system components.




5. Lightly pull on the injector tube and use a small pocket screwdriver to remove the injector from the manifold.
