1. Fuel consumption records must be available before the high fuel consumption complaint can be verified. If symptoms indicate low power, then the low power test should be conducted first, because it could be the cause of the fuel consumption problem. This Primary Engine Test for High Fuel Consumption is the same as the Primary Engine Test for Low Power.2. Visually inspect the fuel system from the fuel tank to the fuel injection lines to see if there are any indications of fuel leaks. Tighten any loose connections found and, if necessary, replace lines that can not be repaired.3. Check the crankcase oil level and the coolant level of the radiator. Remove the boost air line from the AFRC (air-fuel ratio control) during the Primary Engine Test. This will prevent the AFRC from becoming pnuematically activated during the checks. If activated, the AFRC could give an indication of a problem when there is none.4. A slightly lower rpm (15 rpm below low limit) should be expected for the engine in vehicle than the rpm shown in the RACK SETTING INFORMATION. This is caused by the parasitic loads of the engine accessories involved.5. With the engine running, the throttle must have enough travel for the governor control lever to break over (go past the normal governor stop for high idle position) a small amount when the throttle pedal is fully depressed. If full travel is not available, disconnect throttle linkage from governor lever. With throttle linkage disconnected, full travel of governor lever will indicate linkage problems, and the linkage will
