Replacing Your Fuel Injector Seals
The fuel injectors of your vehicle are part of a high pressure fuel delivery system. The whole system must be sealed tight to prevent any leaks that might cause your engine to malfunction. The fuel injector seals are one such precaution against leaks. Damage or wear to these seals require your immediate attention and must be replaced. p>

Removing the old fuel injector seals
Step 1:Open the hood of your car to access the engine compartment.
Step 2:Disconnect your battery by taking out the battery cable from the negative terminal. This will prevent any sparks that could come into contact with the fuel and cause fire.
Step 3:Locate the fuel rail of your engine and look for its Schrader valve.
Step 4:Relieve the pressure of the fuel system by using the screwdriver on the Schrader valve. Push on the small metal rod inside to release the pressure. Be sure to cover the valve opening with a rag to catch any fuel that is released.
Step 5:Disconnect the fuel line from the fuel rail.
Step 6:Disconnect the electrical system from the fuel injectors.
Step 7:Disconnect the fuel injectors from the fuel rail before pulling them out from the engine.
Step 8:Remove the top and bottoms seals of the fuel injector.
Step 9:Install the new seals to the fuel injector.
Step 10:Put a little engine oil on the seals.
Step 11:Put the fuel injectors back into the engine.
Step 12:Reconnect the fuel injectors to the fuel rail.
Step 13:Reconnect the fuel injector's electrical system.
Step 14:Reattach the fuel line to the fuel rail.
Step 15:Reattach the battery cable to the battery's negative terminal.
Step 16:Turn the car on for about five minutes and check for any leaks around the fuel injectors.
Remember to disconnect the car battery before working on the car's fuel system. Any sparks that come into contact with the fuel could accidentally start a fire that may cause serious injury, even death.
Clean of any leaked fuel with rags. Pooled engine fuel poses a serious fire hazard.
