Fuel Test Procedure.
(1)
Adjust valves so that fuel can be pumped through the section being tested to exhausting air.
(2)
Slowly pump fuel into the system, not to exceed a flow rate of 200 gpm. When all air is evacuated,
discharge valves should be closed, the section should be filled with fuel and the pump should be stopped.
(3)
Check all connections for leaks.
(4)
Start the pump and raise pressure to 25 psi, stop the pump, check for leaks, and check gauges.
(5)
If no leaks are found and gauges are okay, start pump and raise pressure to selected test pressure.
(6)
Stop pump, check for leaks, and hold the test pressures for a period long enough to inspect the entire
system under test.
(7)
If leaks are found, relieve pressure, drain leaking section, and make repairs, adjustments, or replacements
as necessary. Retest after repairs are made.
