3) Inspection of Fuel Pump
1. Remove fuel hoses (2) from fuel pump.
2. Connect vacuum/pressure gauge to inlet of fuel pump.
3. Close fuel pump outlet with a finger and apply specified
pressure. Check if no air leaks.
4. With the outlet closed, apply specified vacuum pressure to
check that no air leaks.
5. Connect vacuum/pressure gauge to outlet of fuel pump.
6. Apply specified pressure to check if no air leaks. Replace if
necessary.
