Page 15: Priming The Fuel System
Priming the Fuel System - CHAPTER 2: FUEL FILTER NOTE Depending on the vehicle’s fuel system configuration, the fuel filter housing may not completely drain of fuel. If this is the case, take care when installing the new filter as this may cause fuel to spill from the filter housing. If available, using a vacuum pump, apply vacuum to the engine's fuel return port for 7 minutes, then reconnect the return line. - Page 16 PRIME (closed) position (see "PACCAR Fuel Blending Valve Position") before starting the priming procedure. The valve only rotates 90° left or right. Whether or not your vehicle is equipped with a PACCAR fuel blending valve, continue to Step 3.
- Page 17 If the engine is cranked excessively, Starter Protection will be triggered and starter engagement will be restricted for 10 minutes. NOTE Allowing the engine to idle for several minutes with the PACCAR fuel blending valve in the prime (closed) position assists in purging air from the fuel system.
