1. On the panel 40VU:  On the panel 40VU:
 -push (in) the L TK PUMPS 1 and  - the OFF lights go off 2 (R TK PUMPS 1 and 2) P/BSW. - the FAULT lights come on momentarily.
 The fuel feed-line to the LP valve is pressurized.
 2. Keep the fuel feed line
 pressurized for three minutes,
 then examine these parts for fuel
 leakage:

 -
the main fuel feed-line (3)

 -
the LP valve externally.

 Fuel leakage from these parts
 is not permitted.

 3. On the panel 40VU:  On the panel 40VU:
 -release (out) the L TK PUMPS 1  - the L TK PUMPS 1 and 2 (R TK PUMPS 1 and 2 (R TK PUMPS 1 and 2) and 2) P/BSW OFF lights come on. P/BSW.
