Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Removal Procedure
An 8-digit part identification number is on a mylar label affixed to the fuel meter body assembly. Refer to the number if servicing or part replacement is required.
- Relieve the fuel system pressure. Refer to Fuel Pressure Relief .
- Remove the upper intake manifold assembly. Refer to Upper Intake Manifold Replacement in Engine Mechanical - 4.3L.
- Before removal, clean the fuel meter body assembly with a spray type engine cleaner, such as GM X-30A or the equivalent, if necessary. Follow the package instructions. Do not soak the fuel meter body assembly in liquid cleaning solvent.
Do not use any solvent that contains Methyl Ethyl Ketone (MEK). This solvent may damage fuel system components.
