Vehicles With Fuel Rail Test Port

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1999 Dodge Ram Wagon, 1999 Dodge Ram Van, 1999 Dodge Pickup, 1999 Dodge Durango, and 1999 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
  1. Loosen fuel tank filler cap. Ensure ignition is off. Remove protective cap from fuel rail test port.
  2. Place one end of Fuel Pressure Release Hose (C-4799-1) into an approved fuel container. Attach remaining end of hose to fuel rail test port. Use care, as fuel system may be under pressure. Fuel pressure will be released from fuel system. Remove hose, reinstall protective cap, and fuel tank filler cap.
  3. Wait 5 seconds. Use care when disconnecting fuel lines, as some fuel pressure may still exist in fuel lines.
NOTE: One or more DTCs may set when fuel pump relay is removed. Clear DTCs from PCM after fuel pressure release procedure. To clear DTCs from PCM, see CLEARING DTCS under SELF-DIAGNOSTIC SYSTEM in appropriate SELF-DIAGNOSTICS article.
