9. Transfer Pump Inlet Regulator (TPIR) Flow Test
Refer to Illustration 55 .
A. Disconnect the TPIR return line from the drain port on the
TPIR. Install a suitable blanking cap on the open port in the
TPIR return line.
B. Connect a temporary drain line to the drain port on the
TPIR.
C. Place the end of the temporary drain line into a suitable
calibrated container.
D. With the isolator switch in the ON position but the engine
not running, use a suitable multimeter to measure the input
voltage to the EFLP. Record the reading.
E. With the isolator switch in the ON position but the engine
not running, measure the fuel flow from the temporary drain
line.
F. Refer to Illustration 56 or 57 for the minimum acceptable
flow rate.
G. Remove the temporary drain line from the drain port on the
TPIR. Connect the TPIR return line to the TPIR.
TPIR flow rate Result: The fuel flow is greater than the minimum limit.
Proceed to Test Step 11.
Result: The fuel flow is less than the minimum limit.
