FUEL INJECTION TIMING
Determining the Fuel Injection Timing
Specification
1. Locate and record the fuel injection pump
timing index number (Figure 7-33, (1)) stamped
into the boss on the engine side of the fuel
injection pump housing (Figure 7-32, (1)). Treat
this number as though there is a decimal point
between the two digits. i.e. 68 = 6.8
