Without Scan Tool

  1. Locate service test port on fuel rail transfer line and remove protective cap. Connect Gauge Bar (53476) to Fuel Gauge Pressure Adapter (309725) using a flexible hose from Gauge Bar Set (SA9127E). Make sure needle valve on pressure adapter is closed (Off). Do not use any tools to tighten the adapter to the fuel line pressure port.
  2. If the adapter will not seal with finger tightening, then the seal is defective or damaged and needs to be replaced. Excessive torque on the adapter will damage the fuel line test port. Connect pressure adapter to fuel line test port. Route drain hose from pressure adapter into a suitable container or route fuel back to fuel tank. Open valve on pressure adapter and bleed off pressure (and fuel).
