2005 Grand Cherokee WK Fuel Pump — In-Tank Module for 3.7L / 4.7L / 5.7L
The all-new 2005 Grand Cherokee (WK) introduced three engine choices — the 3.7L V6, 4.7L V8, and the legendary 5.7L Hemi V8. All share the same in-tank fuel pump module mounted atop a 21.5-gallon steel tank. There is no access panel under the rear seat; the tank must be dropped or tilted for module replacement.
Fuel pump module: Delphi FG0913, Airtex E7196M, or Bosch 69766; verify sending unit arm length for 21.5-gallon tank.
Relieve fuel pressure at the Schrader valve on the fuel rail before disconnecting lines — wrap in a shop towel.
Tank strap bolts are 15mm; torque to 30 ft-lb on reinstall. A helper or transmission jack is essential for safe lowering.
The pump module lock ring is plastic and uses a special spanner wrench (Lisle 60430) — do not hammer it off.
Replace the fuel filter sock (strainer) and O-ring seal that comes with the new module; reusing the old seal causes vapor leaks.
On Hemi models, the pump module includes the fuel pressure regulator — verify part number compatibility with 5.7L (58 psi rail pressure).
