High Fuel Pressure Test
Check as follows:
- Tee in a pressure gauge into the return line after the fuel pressure regulator.
- Start the engine and monitor the gauge.
- Is the pressure reading on the gauge above 21 kPa (3 psi)?
- If yes, check the fuel return line for damage (kinked, internally collapsed, or bent closed). If damaged, repair as needed.
- If no, replace the fuel pressure regulator.
