A leak in the fuel system is never a good thing. One of the many causes of these leaks can be traced to the Electro Hydraulic Actuator(EHA) valve of your car. Most of the time, it's better to replace the whole valve rather than repairing it. The replacement procedure may require some automobile know-how.
Difficulty level: Moderate
Tools that you'll need:
- EHA valve
- Socket set
- Ratchet set
Step 1: Access the engine compartment of your vehicle.
Step 2: Disconnect the battery to prevent any accidental fire.
Step 3: Locate the EHA valve in the compartment by consulting with the repair manual of your car. It is usually mounted to the side of the fuel distributor.
Step 4: Carefully remove anything in the way of the EHA valve.
Step 5: Put a drip pan underneath the EHA valve to catch any fuel that may spill. If the drip pan does not fit underneath or if there are none present, you can put some rags underneath instead.
Step 6: Remove the electrical cable connected to the valve.
Step 7: Remove the bolts securing the EHA valve.
Step 8: Remove the valve from the distributor.
Step 9: Remove the O-rings from the distributor ports that connect to the EHA valve.
Step 10: Insert the new O-rings in the distributor port.
Step 11: Install the new EHA valve to the fuel distributor and reattach the bolts.
Step 12: Connect the electrical cables to the EHA valve.
Step 13: Wipe off any fuel that has spilled on the engine compartment with a rag.
Step 13: Reassemble the engine compartment and reattach the battery.
Step 14: Start your car and check the EHA valve for any leaks.
Always remember to disconnect the battery when working on a car's fuel system. This will prevent any fire caused by sparks coming into contact with the fuel.
