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. Bend the loop adaptor (#060-2501) in half for one second to restrict pressure and then
release it.
4. Observe the Fuel Pressure gauge on the unit.
• This will give a good indication of the maximum pump output capabilities.

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

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

protect against residual fuel spray.
7. Disconnect the battery leads, hoses, and adaptors. Return the vehicle fuel system to
its normal operating condition by re-connecting the vehicle fuel lines.
