Fuel-It BMW N54 and N55 Stage 2 Bucketless LPFP Upgrade for 1M, 135i and 335i
Unlock reliable fueling for your tuned BMW N54 or N55 with the Fuel-It Stage 2 Bucketless Low Pressure Fuel Pump (LPFP). This complete E85-certified bucketless assembly replaces the factory LPFP for a high-flow, plug-and-play upgrade that is proven on road and dyno. Ideal for BMW 1M, 135i and 335i owners chasing consistent fuel pressure on ethanol blends, this upgrade delivers the flow you need for big power and daily-drive dependability.
Why choose this BMW N54/N55 LPFP upgrade
- E85 certified bucketless LPFP assembly for ethanol blends and high octane fuels
- Up to 25% more flow than the standard Fuel-It Stage 2 upgrade
- Up to 150% more flow than the stock BMW E chassis LPFP
- Supports up to 550 whp on 85% ethanol and up to 600 whp on 50% ethanol
- Plug-and-play installation by replacing your stock fuel pump bucket
- Stable low pressure delivery for tuned N54 and N55 engines on E blends
What’s included
- Complete plug-and-play bucketless LPFP assembly
- Custom billet aluminium anodised bracket for the pump and float assembly
- New E85 compatible Walbro pump
- New Walbro filter
- Custom anodised billet fitting for pump output to stock fuel line connection
- Spare vent tube clip
- Two cotter pins to secure your float assembly
Performance and use case
This high-flow BMW LPFP upgrade is perfect for N54 and N55 owners running remaps, hybrid turbos or ethanol blends who need consistent low pressure fuel delivery. Expect strong, reliable fuel pressure under load on E50 to E85 blends when paired with appropriate tuning. If you prioritise straight-line performance and want maximum flow from a bucketless design, this is the go-to solution.
Important notes on filter options and fuel level
The standard kit includes a basic filter assembly. Running the vehicle at very low fuel levels can cause fuel starvation:
- For hard straight-line acceleration with less than 1/8 tank, we recommend adding the Fuel-It Option 1 Filter Upgrade.
- For road course applications, you may see starvation on long, high-G right turns when running less than a half tank. For track use in those conditions, we recommend the Fuel-It standard Stage 2 pump.
