Peugeot 307 (1st generation) 1.4 16V (2003): Fuel Pump Module with Fuel Level Sensor Removal and Installation

The fuel pump module on the Peugeot 307 is located inside the fuel tank. It is accessed from above through an access panel under the rear seat, so the tank does not need to be removed. This job is needed when there is no fuel delivery, the fuel level gauge reads erratically, or the pump is noisy. The main risks are gasoline and its vapors, and damage to the float and seal during installation. The exact procedure and exact torque specifications for this variant are not confirmed in publicly available sources, so a general procedure is given below.

Difficulty: Medium Time: 1-2 hours Steps: 14 Tools: Screwdriver set, flat-blade screwdriver or brass drift for the lock ring, tweezers or a fuel line quick-connect release tool, wrench for disconnecting the battery terminal, shop rags, fire extinguisher nearby, container for leftover fuel

Parts

2
  • 🔩 Fuel pump module with fuel level sensor (complete pump assembly with strainer, float-type level sensor and housing), plus the module cover seal ring. This is a complete assembly
  • 🔩 the pump, strainer and sensor are also sold separately as individual components. Look up the part number by VIN to avoid getting the wrong module variant

Step by step

14 steps
  1. Work outdoors or in a well-ventilated area, away from sparks and open flames. Ideally, run the tank down to a minimum: a fuel level below a quarter tank noticeably reduces the risk of spills.
  2. Disconnect the negative battery terminal. To relieve pressure in the fuel line, start the engine with the fuel pump relay or fuse removed, let it stall, then crank it with the starter for 2-3 seconds. Check the fuse box cover for the location of the pump relay and fuse.
  3. Slide the rear seat cushion forward and remove it. On the 307 it is held by clips and usually lifts off with a sharp upward pull on the front edge. Fold back the carpet underneath.
  4. Find the round or oval access panel in the floor. Clean it and the surrounding area with a vacuum and a brush so dirt does not fall into the tank when it is opened. Remove the panel cover if it is held by screws or clips.
  5. Disconnect the module's electrical connector by pressing the locking tab.
  6. Disconnect the fuel supply and return hoses from the fittings. They use quick-connect retainers: press or pry the retainer, and do not pull the hose with force. Place rags underneath; the spill will be small. Remember or mark which hose goes where.
  7. Remove the module lock ring. It is usually plastic or metal and turns counterclockwise; tap on its tabs with a brass drift or a screwdriver through a rag. Do not use any tool that can create a spark.
  8. Carefully lift the module straight up, tilting it as needed so you do not bend the float arm of the level sensor. Let the remaining fuel drain from the housing into the prepared container. Do not drop anything into the tank.
  9. Inspect the strainer, float, electrical connector and seal. If you are replacing only the level sensor or the pump, disassemble the module into its components without damaging the housing. If you are replacing the whole module, compare the length and position of the float with the old one.
  10. Fit the new seal ring in its seat, lightly lubricating it with clean gasoline or a silicone grease made for fuel systems. Do not use oil or ordinary grease.
  11. Lower the module into place, aligning the marks or guide tabs with the opening, and make sure the float moves freely and does not catch on the tank walls.
  12. Install the lock ring and tighten it by hand until it stops against the tabs, without excessive force. Connect the hoses until they click, then the electrical connector.
  13. Put the pump relay or fuse back, reconnect the battery, turn the ignition on for a few seconds 2-3 times to let the pump build pressure, and check the joints for leaks. Then start the engine and inspect the access panel again.
  14. Check the fuel gauge reading with a full tank and, if possible, with a low tank. If the gauge is inaccurate, recheck the float position and the connector. Then reinstall the access panel cover, carpet and seat cushion.

Common mistakes and warnings

  • Gasoline and its vapors are highly flammable: no smoking, no power tools that can spark and no open flames nearby. If you have no experience working on fuel systems, it is better to leave the job to a repair shop. After reassembly, do not leave the car with a gasoline smell in the cabin until the cause is fixed.
