Electric Fuel Pump Assembly For BMW E46 Series 323i 323Ci 325i 328i 325xi 330i 1999-2006 2.5L 2.8L 3.0L, 4Pins

Extended cranking, intermittent no-start, stalling, low fuel pressure, weak acceleration, fuel starvation with fuel still indicated, or an inaccurate fuel gauge can indicate a fault in the E46 saddle-tank system. The BDFHYK E8416M is a 4-pin right-side or passenger-side in-tank fuel delivery module for the specific BMW E46 gasoline applications listed below. Confirm the exact model, year, engine, right-side position, 4-pin connector, flange, outlet, module height, sender layout, and OE reference against the removed assembly.

Detailed BMW E46 Applications

• 2000 BMW 323Ci with the 2.5L gasoline engine
• 1999–2000 BMW 323i with the 2.5L gasoline engine
• 2001–2006 BMW 325Ci with the 2.5L gasoline engine
• 2001–2005 BMW 325i and 325xi with the 2.5L gasoline engine
• 2000 BMW 328Ci with the 2.8L gasoline engine
• 1999–2000 BMW 328i with the 2.8L gasoline engine
• 2001–2005 BMW 330Ci, 330i, and 330xi with the 3.0L gasoline engine

This listing is for the E46 gasoline platform and the 4-pin right-side delivery unit. It is not the left-side level sensor, an engine-mounted high-pressure pump, or a later BMW chassis module.

Confirm the Right-Side 4-Pin Delivery Unit

The E46 saddle tank uses position-specific components. Compare the removed right-side assembly with the product images and verify the 4-pin connector, locking flange, fuel outlet, reservoir, module depth, strainer, float arm, and sender arrangement. The left-side fuel-level sensor and transfer path are separate service points and can also affect fuel supply or gauge behavior.

E8416M and BMW 16146766942 Cross-Reference

Common references include E8416M, 16146766942, 16146752499, 16146752895, 16141184276, FG0415, P76300M, SP5008M, Bosch 67896, VDO 228222009002Z, and FPA61923. Match the OE number, 4-pin connector, and right-side module before installation.

BMW E46 Saddle-Tank Diagnosis

• Scan for fuel-delivery, mixture, voltage, and sender-related faults.
• Check the fuel-pump fuse, relay, power feed, ground, connector, and voltage under load.
• Measure low-side fuel pressure and residual pressure.
• Inspect the fuel filter and integrated pressure-regulator arrangement where applicable.
• Check the left-side level sensor and siphon or transfer function when one tank chamber remains full.
• Inspect the tank for water, sediment, or deteriorated fuel.

Replacing the right-side module will not correct a failed relay, damaged wiring, restricted filter, failed regulator, left-side sender fault, or tank-transfer problem. Complete the relevant BMW diagnostic procedure first.

BMW E46 Right-Side Module Installation

1. Relieve fuel pressure and disconnect the battery.
2. Clean the right-side service opening before removing the module.
3. Record the connector, fuel line, flange, strainer, and sender orientation.
4. Inspect the left-side sender and transfer path when fuel distribution is uneven.
5. Install a new seal and seat the retaining ring correctly.
6. Keep the float arm and strainer clear of internal tank structures.
7. Reconnect the 4-pin plug and fuel line without forcing aged plastic fittings.
8. Prime the system and inspect for leaks.
9. Verify pressure, starting, fuel transfer, and both fuel-level readings.

Do not operate the pump while dry. Confirm the right-side position and 4-pin connector before reconnecting the battery.
