Fuel Injection Supply Manifold
REMOVAL
1. Remove intake manifold.
2. Disconnect fuel line spring lock couplings.
WARNING: FUEL SUPPLY LINES WILL REMAIN PRESSURIZED FOR LONG PERIODS OF TIME AFTER ENGINE SHUTDOWN. FUEL SYSTEM PRESSURE MUST BE RELIEVED PRIOR TO FUEL SYSTEM SERVICE TO PREVENT POSSIBLE INJURY.
3. Disconnect connectors from engine control sensor wiring at fuel injectors. Disconnect vacuum hose at fuel pressure regulator.
4. If required, remove fuel pressure regulator and fuel pressure relief valve from the fuel injection supply manifold.
5. Remove four retaining bolts and remove fuel injection supply manifold.
INSTALLATION
1. Install fuel injection supply manifold, and make sure all fuel injectors are properly seated.
WARNING: ALWAYS USE NEW O-RINGS WHEN ASSEMBLING FUEL INJECTION SUPPLY MANIFOLD COMPONENTS TO AVOID COMBUSTION FROM FUEL LEAKAGE.
2. Install four fuel injection supply manifold retaining bolts. Tighten to 15-23 N.m (11-16 Lb-Ft).
3. If removed, install the fuel pressure relief valve and fuel pressure regulator to the fuel injection supply manifold.
4. Connect engine control sensor wiring at fuel injectors.
5. Connect fuel line spring lock couplings.
6. Install intake manifold.
7. Connect vacuum line to the fuel pressure regulator.
8. Run engine and check for fuel leaks.
