Solution

1. Preparation

Tools Required: Socket set, torque wrench, OBD-II scanner, fuel pressure gauge, safety goggles, gloves.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Repair Fuel Lines

Sub-steps:
1. Locate the fuel lines running from the fuel tank to the engine.
2. Use a socket set to remove any protective covers if necessary.
3. Inspect the lines visually for cracks or leaks.
4. Replace any damaged lines with OEM replacements, ensuring all connections are tight.
5. Torque connections to manufacturer specifications.

3. Check and Replace Fuel Injector Seals

Sub-steps:
1. Remove the engine cover if applicable to access the fuel injectors.
2. Disconnect the electrical connectors from the fuel injectors.
3. Carefully remove the fuel injectors from the intake manifold.
4. Inspect the O-rings on each injector for damage.
5. Replace any damaged O-rings and reassemble the injectors, ensuring proper seating.

4. Examine and Repair Fuel Tank

Sub-steps:
1. Safely lift the vehicle using jack stands.
2. Inspect the fuel tank for cracks or rust.
3. If damage is found, remove the tank using the socket set, disconnecting all necessary lines and electrical connectors.
4. Replace the fuel tank with a new one if necessary, ensuring all connections are secure and torqued to specifications.

5. Conduct a Pressure Test

Sub-steps:
1. Attach a fuel pressure gauge to the fuel rail.
2. Turn the ignition on (without starting the engine) to pressurize the system.
3. Check the gauge reading against manufacturer specifications.
4. If pressure is low, recheck connections and inspect for leaks again.
