Extended cranking, intermittent no-start, stalling, low fuel pressure, weak acceleration, or an inaccurate fuel gauge can indicate a fault in the low-pressure tank system. The BDFHYK E8688M is a right-side or passenger-side in-tank fuel pump module for specified BMW 1 Series, 3 Series, and X1 applications associated with OE 16147163298. Confirm the chassis code, engine, right-side position, flange, connector, fuel outlet, module height, sender layout, and OE reference against the removed assembly before installation.

E8688M Right-Side Fuel Pump Module for Selected BMW Applications

Listed BMW Model Coverage

2006 BMW 325i, 325xi, 330i, and 330xi
2007–2013 BMW 328i and 335i
2007–2008 BMW 328xi and 335xi

2013 BMW 135is
2013–2015 BMW X1 configurations associated with this module

Body style, chassis code, engine code, drivetrain, and production date must be checked. A broad BMW model name or engine displacement is not sufficient to confirm the correct tank module.

Confirm the Right or Passenger-Side Tank Position

This module is associated with the right side of the saddle-style fuel tank. Compare the removed unit with the product images and verify the flange, electrical socket, fuel outlet, reservoir, module depth, seal, and fuel-level sender arrangement. Do not confuse the right-side pump module with the opposite-side level sensor or transfer unit.

E8688M and BMW 16147163298 Cross-Reference

Common references include E8688M, 16147163298, 16 14 7 163 298, A2C53025280, FG0917, P76486M, SP5009M, and 228235018007Z. Match the OE number to the exact chassis and physical module before opening the tank.

Separate Low-Pressure Pump Faults From Other BMW Fuel Faults

Scan the vehicle for fuel-pressure, mixture, voltage, and pump-control faults.
Check the low-pressure pump fuse, wiring, ground, connector, and pump-control module command.
Measure low-side fuel pressure and voltage under load.
Separate the in-tank low-pressure pump from the engine-mounted high-pressure pump where applicable.
Check the opposite-side transfer system and fuel-level sensor when the gauge or fuel transfer is abnormal.
Inspect the tank for water, sediment, or contaminated fuel.

Replacing the tank module will not correct a failed pump-control module, high-pressure pump, wiring fault, transfer problem, or engine-management issue. Complete the relevant BMW diagnostic procedure first.

BMW Saddle-Tank Installation and Final Checks

Relieve fuel pressure and disconnect the battery.
Clean the service opening before removing the right-side module.
Record the fuel line, connector, flange, and sender orientation.
Inspect the opposite side and transfer path when fuel distribution is uneven.
Install a new seal and seat the retaining ring correctly.
Keep the float arm, strainer, and internal transfer connections unobstructed.
Reconnect the line and electrical plug without forcing aged plastic fittings.
Prime the low-pressure system and inspect for leaks.
Verify low-side pressure, engine starting, transfer operation, and fuel-gauge response.

Do not run the pump dry. Confirm that the module is installed on the correct tank side before reconnecting the battery.

What’s Included in This Fuel Pump Assembly

Complete fuel pump module
Integrated fuel level sending unit
Fuel strainer (filter sock)
Housing and mounting components

This fuel pump assembly is designed as a direct replacement unit that restores proper fuel delivery and fuel level monitoring.

Estimated Installation Time

Professional mechanic: 1–2 hours
DIY installation: 2–4 hours

Fuel pump replacement usually requires accessing the fuel tank or service panel depending on the vehicle design. Always disconnect the battery and relieve fuel system pressure before installation.

Pump Only vs Fuel Pump Assembly

Option	Description
Replace Pump Only	Lower parts cost but requires disassembling the existing module and reusing older components.
Replace Complete Assembly	A complete module designed for direct installation, helping restore reliable fuel delivery more efficiently.

Most modern vehicles use integrated fuel pump modules, which makes replacing the full assembly the more reliable solution.

Q: Which BMW models are listed for E8688M?

A: Specified BMW 1 Series, 3 Series, and X1 applications associated with OE 16147163298 are listed. Exact chassis and engine verification is required.

Q: Which side of the tank does E8688M fit?

A: It is associated with the right or passenger side of the saddle-style fuel tank.

Q: Does the module include a fuel-level sender?

A: The E8688M/16147163298 configuration includes the right-side pump and fuel-level sensor arrangement. Compare the pictured assembly with the removed unit.

Q: Can E8688M replace the opposite-side sender?

A: No. The opposite side can use a separate level sensor or transfer component with a different design and function.

Q: Which reference numbers should be checked?

A: Check E8688M, BMW 16147163298, A2C53025280, FG0917, P76486M, SP5009M, and 228235018007Z.

Q: Is the model name enough to confirm fitment?

A: No. Confirm chassis code, engine code, drivetrain, production date, right-side position, and physical module configuration.

Q: Is this the engine-mounted high-pressure fuel pump?

A: No. This is the low-pressure in-tank module. Some BMW engines also use a separate high-pressure pump.

Q: What electrical parts should be diagnosed?

A: Check the pump-control module, fuse, wiring, ground, connector, command signal, and voltage under load.

Q: What should be checked on a saddle tank?

A: Inspect fuel transfer between tank chambers and the opposite-side sensor or transfer unit when the gauge or fuel supply becomes irregular.

Q: What must be verified after installation?

A: Prime the low-pressure system, inspect for leaks, confirm pressure and starting, and verify fuel transfer and gauge response.
