1. On a typical diesel subsystem, what system would Primary filter
most likely be used at the lowest pressure when the
engine is running?
2. Where is the secondary fuel filter usually located? on the side of the transfer
pump

tant role in a high-flow fuel system as a:
4. What could be used to test the low-pressure side of a Negative pressure gauge
typical diesel fuel subsystem for inlet restriction?
5. Which of the following should fuel subsystem charging D
pressures be measured with?
a.) Diagnostic sight glass
b.) H20 manometer
c.) HG manometer
d.) Accurate pressure gauge
6. What type of fuel transfer pump is more commonly Gear pumps
