ISSUE: A new warranty-reimbursable method is now available for cleaning standard design pintle fuel injectors. (Deposit Resistant Injectors "DRI's" do not require cleaning.) This new method is an alternate to the current procedure which utilizes the Rotunda Fuel lnjector Tester/Cleaner and is reimbursable as specified in the Labor Time Standards Manual.
ACTION: If standard design pintle fuel injectors require cleaning, use the new cleaning method which utilizes Motorcraft Pressurized Fuel lnjector Cleaner (CM-1001) and the Motorcraft Fuel Injection Cleaning Kit (CM-1000). Both of these items are available from the regular Parts Distribution System or the local Motorcraft Distributor.
The kit features:
^ Application for most Ford and Lincoln-Mercury EFI vehicles.
^ Application for most other domestic and import EFI vehicles.
^ Effective for both central and multi-port EFI systems.
^ Quick and easy hook up.
^ Uses pre-mixed Motorcraft Pressurized Fuel Injector Cleaner.
^ Environmentally-compatible can pressurizing.
^ Steel wire-reinforced hoses.
^ Easy-to-follow illustrated Instruction Manual provides step-by-step connection and cleaning procedures.
^ Includes replacement parts kit with seals, washers, regulator diaphragms and dust caps.
^ Full 1-year Manufacturer's Warranty on defects in materials and/or workmanship.
^ Completely reorderable components.
