High Pressure Fuel Line Leaks
WARNING: This page is about a different car, the 2007 Chrysler PT Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
High-pressure fuel lines deliver fuel under extreme pressure from the injection pump to the injectors. This maybe as high as 1600bar (23,200psi). Use extreme caution when inspecting for high-pressure fuel leaks. Fuel under this amount of pressure can penetrate skin causing personal injury or death. Inspect for high-pressure fuel leaks with a sheet of cardboard placed in the suspected area while the engine is not running. Start the vehicle and allow the engine to run for a short period. Turn the engine off and inspect the piece of cardboard. Wear safety goggles and adequate protective clothing when servicing fuel system.

High-pressure fuel line (1) leaks can cause starting problems and poor engine performance.
- Turn the engine off.
- Place a piece for cardboard (2) in the suspected area. See Fig 1.
- Start the engine and allow to run for a short period.
- Turn the engine off.
- Inspect the cardboard.
If a high-pressure line connection is leaking, counterhold and tighten the connection to specification then perform this procedure again. Replace any damaged, restricted or leaking high-pressure fuel lines with the correct replacement line.
CAUTION:
The high-pressure fuel lines cannot contact each other or other components. Do not attempt to weld high-pressure fuel lines or to repair lines that are damaged. Only use the recommended lines when replacement of high-pressure fuel line is necessary.
