High Pressure Fuel Line Bleeding
WARNING: The fuel injection pump supplies high-pressure fuel of as high as 120,000 kPa (17,405 psi) to each individual injector through the
high-pressure lines. Fuel under this amount of pressure can penetrate the skin and cause personal injury. Wear safety goggles and adequate
protective clothing and avoid contact with fuel spray when bleeding high- pressure fuel lines.
WARNING: Do not bleed air from the fuel system of a hot engine. Do not allow fuel to spray onto the exhaust manifold when bleeding air from
the fuel system.
Bleed air from one injector at time.
1. Loosen the high-pressure fuel line fitting at the injector.
2. Crank the engine until all air is bled from the line.
-
Do not operate the starter motor for longer than 30 seconds.
-
Wait two minutes between cranking intervals.
3. Start the engine and bleed one injector at a time until the engine runs smoothly.
4. Tighten fuel line(s) at injector(s) to 30 N.m (22 ft. lbs.) torque.
