Fuel Meter Body Cleaning
CLEANING AND INSPECTION
Removing the fuel meter body assembly from the engine requires removing the top portion of the intake manifold, called the upper manifold assembly
and throttle body.
An 8 digit part identification number is on a mylar label affixed to one of the fuel meter body assemblies. Refer to this number if servicing or part
replacement is required.
NOTICE: Do not use a cleaner which contains methyl ethyl ketone. This extremely strong solvent is not necessary for this type of cleaning. Use a
carburetor cleaner in order to remove deposits. Refer to the package instructions on the use of the product.
NOTICE: Cover the injector sockets in order to prevent dirt and other contaminants from entering the open fuel passages.
-
Before removal, the fuel meter body assembly may be cleaned with a spray type engine cleaner, GM X-30A or the equivalent.
-
Follow the package instructions.
-
Do not soak fuel meter body assemblies in liquid cleaning solvent.
