Note. The fuel system is designed to allow specified maximum vacuum and pressure conditions. Do not deviate from the vacuum and pressure tests in these procedures. Excessive pressure/vacuum will damage the EVAP components or eventual cause fuel tank failure.

Special Tools Required

  1. Vacuum/Pressure Gauge, 0-4 inHg 07JAZ-001000B
  2. Vacuum Pump/Gauge, 0-30 inHg Snap-on YA4000A or equivalent, commercially available

Note. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ). Fresh fuel has a higher volatility that creates greater pressure/vacuum. The best condition for testing is less than a full tank of fresh fuel. If possible, to assist in leak detection, add 1 gallon of fresh fuel to the tank (as long as it will not fill the tank), just before starting these procedures.
