Fuel System Pressure Test

Verify that Setup Steps 1-10 from the appropriate previous chapter have been

completed for the specific fuel system type to be tested

2. Verify that the vehicle’s engine is running and check connections for leaks.

3. Note the vehicle’s fuel system pressure reading from the Fuel Pressure gauge on the

control panel of the unit.

• This is the vehicle’s running pressure. If the pressure is erratic or the vehicle is slow to reach

maximum pressure, the vehicle’s fuel filter may be clogged or its fuel pump

may be weakening.

4. Return to the appropriate previous chapter, Fuel System Cleaning Procedures, to

continue the cleaning process. Otherwise, conclude the test as described below.

5. Turn the vehicle off.

IMPORTANT

Close the gate valve on the T-adaptor and wrap a shop

towel around pressure fittings before disconnection to

protect against residual fuel spray.

6. Disconnect the battery leads, hoses, and adaptors. Return the vehicle fuel system to

its normal operating condition by re-connecting the vehicle fuel lines.
