_ AMM TASK 28-21-45-400-003).
NOTE : Sequence valves are not fitted to the center tank pumps
____ but the fuel pump pressure can be tested using the same procedure. The fuel output pressure of the center tank fuel pumps is more than that of the wing tank fuel pumps.
2 Do Para. 4.D. (Preparation for Test) thru Para. 4.G. (Test of
_ the Sequence Valve) on the center tank fuel pump, No. 1(2).
3 Make sure that the fuel pressure for the center tank pumps is
_ more than approximately 2.76 bar (40.0 psi).

NOTE : The fuel pressure given here for this test is without a____
fuel transfer.
4_ If the fuel pressure is less than that specified:
- replace the PUMP-FUEL NO 1, CTR TK (37QA) (PUMP-FUEL NO 2,
CTR TK (38QA)) (Ref. AMM TASK 28-21-51-000-002) and (Ref.
AMM TASK 28-21-51-400-002).
5_ If the fault continues, investigate the reason for the low
pressure and make sure that:
- the fuel pick up strainer and pump input pipe is clear
- the fuel pump/canister outlet pipe work is not damaged and
leaking.
6_ Replace all the unserviceable fuel pipes and strainers.
(9) Do the test given in Para. 3.A.
