Disassembly (Fuel Meter Assembly - Model 700)

  1. Remove fuel meter-to-throttle body retaining screws. Remove fuel meter assembly. See Figure. Discard gasket. If fuel pressure regulator cover is removed, regulator diaphragm must be replaced to prevent fuel leaks.
  2. Remove TPS, IAC, pressure regulator assembly, fuel injector, fuel filter, rubber parts, and diaphragms. Clean all remaining (metal) parts in a cold immersion-type cleaner such as Carbon X (X-55). Blow dry with compressed air. Inspect mating surfaces for damage which may prevent gasket sealing. Repair or replace faulty components.
