Fuel Line Bleeding
WARNING: This page is about a different car, the 1995 Dodge Pickup and 1995 Dodge Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Fuel line bleeding is necessary if fuel filter/water separator is not filled before installing or fuel injection pump is replaced. Bleed high-pressure fuel lines if connections are loosened or replaced. If engine has not been operated for an extended time, bleed fuel lines before next initial engine start-up.
WARNING:
DO NOT bleed fuel lines on a hot engine, as high exhaust temperatures could cause a fire. Carefully bleed fuel lines, as fuel is under extremely high pressure and could penetrate skin. Use safety goggles and protective clothing when bleeding fuel lines.
- To bleed low-pressure fuel lines and fuel filter/water separator, loosen fuel bleed bolt, located in center of fuel supply line banjo bolt. See Fig 1.
- Operate push-button primer on fuel transfer pump until steady fuel stream flows from fuel bleed bolt. Tighten fuel bleed bolt to specification. See TORQUE SPECIFICATIONS . If push-button feels like fuel transfer pump is not operating, rotate engine 90 degrees, and repeat procedure.CAUTION: Ensure parking brake is applied and transmission is in Neutral before bleeding high-pressure fuel lines.
- To bleed high-pressure fuel lines, ensure parking brake is applied and transmission is in Neutral, as engine may start when cranking to bleed air. Carefully loosen high-pressure fuel line nut at fuel injector.CAUTION: DO NOT operate starter for more than 30 seconds when bleeding high-pressure fuel lines. Allow 2-minute intervals between starter operations.
- Operate starter until steady fuel flow exists, and then tighten high-pressure fuel line nut to specification. See TORQUE SPECIFICATIONS . Start engine. Repeat procedure on each high-pressure fuel line until engine operates smoothly.
