2008 Nissan Altima 2.5L — Delphi FE0730 / Airtex E8737M
The 2008 Nissan Altima with the 2.5L QR25DE stores the fuel pump inside the tank under the rear seat. There is a factory access panel on the driver side rear seat cushion — no need to drop the tank. Because the system is returnless with high pressure, always relieve pressure at the Schrader valve on the fuel rail before opening any lines.
Fuel pump module: Delphi FE0730, Airtex E8737M, or Bosch 67959; all include the pump, sender, and strainer basket
Relieve fuel pressure first — remove the fuel pump fuse (No. 25, 15A in the IPDM), crank the engine for 5 seconds, then crack the Schrader valve on the fuel rail with a rag
Lift the rear seat bottom cushion by pulling up sharply on the front edge; the access panel is a black plastic cover held by four Phillips screws
Disconnect the 6-pin electrical connector and the two quick-connect fuel lines — squeeze the white tabs and pull straight up; do not twist the nylon lines
The pump module is held by a plastic locking ring; tap the ring counter-clockwise with a brass drift and hammer to unlock, then lift the module straight out
Transfer the fuel level sender arm and float to the new module carefully — bending the sender arm by even 2mm causes inaccurate gauge readings
System pressure: 51 psi (350 kPa) at idle; if pressure drops below 45 psi under load, the pump is weak and will cause lean misfire codes (P0171)
