This is a complete plug and play solution to replace your stock Low-Pressure Fuel Pump (LPFP) with a new E85 certified bucketless assembly.

This solution provides up to 25% more flow than our standard Stage 2 LPFP upgrade and up to 150% more flow than the stock pump.

This pump will support up to 550whp running 85% ethanol and 600whp running 50% ethanol.

The Stage 2 bucketless kit includes the following:

- A custom anodized billet fitting for the pump output and stock fuel line connection.
- Our custom billet aluminum anodized bracket for the pump and float assembly
- Two cotter pins to secure your float assembly
- A new E85 compatible Walbro 450 pump
- Spare vent tube clip
- A new Walbro filter

If you still need more flow, the Stage 3 upgrade is also available and can be added to your Stage 2 bucketless pump.

The Stage 3 upgrade kit includes:

- A complete plug and play solution by simply adding the secondary module
- Our custom billet aluminum fitting to run both pumps in parallel
- A new E85 compatible Walbro 450 pump
- Wiring harness for the secondary pump
- Spare vent tube clip
- A new Walbro filter

Recommended accessories:
- Lock Ring Removal Tool
- Hobb's switch
NOTE: These kits include a basic filter assembly. When using this filter, running the vehicle under low fuel conditions can cause fuel starvation issues. If you do hard straight line accelerations when you have less than 1/8 tank of fuel, we would recommend running our standard Stage 2, 3, or Stage 4 pump. In addition, if you intend to use this for road course applications, you may see starvation issues when running less than a half tank and doing long high G right turns. Again for those applications we'd recommend one of our standard pump applications.

This is a complete Low Pressure Fuel Pump (LPFP) upgrade that replaces your weak stock LPFP assembly with a high-flow E85-certified one. Standard Kit Includes: A brand new OEM LPFP bucket that is upgraded with a new Walbro 450 or 525 pump and filter. A new E85 compatible Walbro 450 pump (F90000274) that flows 50% more fuel than stock Optional A new E85 compatible Walbro 525 pump (F90000285) that flows 65% more fuel than stock NOTE: Owners with I-Drive may get a Fuel pump warning on the screen that says "Continued driving is possible. Have the system checked by your BMW center as soon as possible." As long as the car is running fine and does not exhibit any other symptoms, there is not an issue with the pump and this can be ignored. If you have any questions about this please feel free to contact us. Upgraded pumps pull more current, so if your EKP (LPFP control module) is weak, it may overheat causing it to shut down and need to be replaced. If this is a concern for you check out our Stage 3 fuel pump upgrade kits that retain the stock LPFP and add a secondary pump.

Introducing the comprehensive N54/N55 Low-Pressure Fueling Solution! With Radium Engineering's Regulated Fuel Hanger Surge Tank at its core, this kit allows you to tailor your fuel pump setup, select an in-line fuel filter, and opt for a wiring kit for multiple LPFP configurations in your N54 or N55-powered E9X 335i. In this setup, the BMW fuel pump serves as a "lift" pump, maintaining fuel volume in the Fuel Hanger Surge Tank via a dedicated orifice. This guarantees sufficient pressure for the venturi jet pump(s) to operate, ensuring consistent fuel delivery. Excess fuel in the FHST cycles back to the OEM tank through a one-way check valve ensuring a steady fuel supply. Unlike conventional surge tanks, which rely on pump flow matching, this FHST employs additional mechanisms to continuously deliver fuel regardless of fluctuations in other fuel sources. When the main tank nears depletion, the lift pump and Fuel Pressure Regulator step in to supply fuel to the FHST. Furthermore, with a boost reference signal (Hobbs Switch), the Fuel Pressure Regulator operates at a 1:1 ratio, allowing fuel pressure to rise proportionally with boost pressure. The low-pressure fuel returning from the Fuel Pressure Regulator is routed back into the surge tank to maintain its fullness. Inside the canister, a 6-hole diverter ensures even fuel dispersion without air bubbles or foaming. The stainless electrical studs included effectively handle high current demands, surpassing the capabilities of compact bulkhead connectors. These resilient connections are sealed against all standard and exotic fuels, with non-conductive acorn nuts provided to prevent accidental short circuits. The kit also includes the necessary electrical hardware for one Walbro fuel pump and the OEM level sender, while the in-tank wiring is insulated with premium chemically resistant ETFE for enhanced durability. If you are planning on running more than one LPFP, you will need to select the Hobbs Switch option for boost reference (to be installed on the manifold or charge pipe), as well as the fuel pump wiring kit! Features: -Drop-In OEM Replacement -Permits 1 or 2 Surge Pumps -1:1 Fuel Pressure Adjustments -Fuel Starvation Protection -Integrated 1-Way Fill Valve -High Current Electrical Hardware -Compatible with Various Pumps -Anodized Aluminum Construction -Gasoline and Ethanol Compliant -Anodized Aluminum 8AN Male Outlet Fitting -Anodized Aluminum Surge Tank Canister -Fuel Resistant Tubing and Wiring -Stainless Steel Hardware -Relay(s) and Fuse(s)
