1. Remove fuel pressure transducer at
secondary fuel filter (para 6-7).
2. Install appropriate pressure gage (para 6-7).
3. Start engine and run at idle
(TM 9-2350-31 1-10). Pressure should be
40 to 70 psi (276 to 483 kPa) at 1500 to 2300
rpm.
Is fuel pressure below 40 psi (276 kPa)?
Go to step F.
1. Install fuel pressure transducer at secondary
fuel filter (para 6-7).
2. Place a 100 psi (690 kPa) gage with a tee
fitting in the primary fuel filter inlet.
3. Disconnect connector from the fuel pump
relay.
4. Place a jumper wire from socket A to socket
