2003 Bmw 325i Sulev Fuel Pump Replacement
Hello Everyone, I am the owner of a 325i SULEV vehicle and it has come time for me to deal with the infamous fuel pump. I got a MIL about a week ago for lean codes which I traced to erratic fuel pressure. I suspected this was coming for the past couple months due to infrequent engine hesitation.
The fuel supply system in a BMW E46 consists of: Fuel Tank Fuel filler with associated breathing and venting pipes Evaporative emissions control valve and pressure pump High pressure fuel pump assembly with fuel filter and fuel level senders Fuel pump relay Fuel pressure regulator Fuel rail and electric fuel injectors A faulty fuel pump can cause poor engine performance and hard starting. This covers the fuel pump replacement on the BMW 3 series,they are pretty simple and easy to replace. The complete replacements part number is 67896 and that's a oem Bosch this is a plug and play.
Here's more info on the SULEV: BMW Owners with Super Low Emission Vehicles - SULEVs If my fuel pump and/or fuel filter were to need service, I could understand why the engine would be running lean and result in the "Service Engine Soon" light and thus failing smog. These brief and simple instructions will show us the main steps on how to disassemble and replace the fuel pump of the BMW 3 Series 325i.

As you press on the gas pedal, the pump pushes gas into the engine instead of pulling it. To remove the pump, you must remove the gas tank. Because you are dealing with gas and gas vapors, this task should only be attempted if you feel comfortable working around gas.
Just was told the fuel pump failure on this vehicle required replacement of the entire fuel tank assembly (part cost approximately $6,500) plus labor. Does anyone have any history with this and getting BMW to cover this under the CALIF Emissions warranty (15yrs 180,000 miiles)? I have had.

The other option I would reluctantly consider is swapping in a non-sulev tank, m3 pump, m3 fuel filter, m3 fuel lines etc + whatever else I'm missing. but id rather keep this project as straightforward (and cheap) as possible.
