Fuel-It Stage 2 Bucketless/Basketless LPFP Upgrade Kit - BMW N54 N55 E-Series In-Tank Low-Side Low Pressure Fuel Pump, High-Flow E85 Ethanol Compatible Walbro Drop-In Plug-and-Play Module for 1M 135i 335i E82 E88 E90 E91 E92 E93 (also fits X1 E84)

BMW N54 N55 in-tank low side fuel system upgrade for E-series 1M, 135i, 335i

Ready to push your turbocharged 6-cylinder further on ethanol blends. This Fuel-It Stage 2 basket-free in-tank pump assembly delivers serious low-side flow, rock-solid pressure stability and simple drop-in installation. It is an ethanol-safe, Walbro-powered module designed for tuned E82, E88, E90, E91, E92 and E93 cars that need dependable supply on E50 to E85 without the hassle.

Key reasons enthusiasts choose this in-tank pump

• Ethanol ready for E85, E50 and high-octane mixes with full E-compatible internals
• Flow headroom that dwarfs the factory unit for consistent rail feed under load
• Approximately 25 percent more flow than the standard Stage 2 configuration and around 150 percent over stock E-chassis supply
• Real-world support around 550 whp on E85 and about 600 whp on E50 with correct calibration
• Direct-fit drop-in module that replaces the OE bucket for fast, tidy installation
• Smooth idle and strong WOT pressure on remapped N54 and N55 engines including hybrids

What you get in the box

• Complete basket-free in-tank fuel pump assembly with plug-in connectors
• Billet anodised aluminium carrier for pump and level float
• New ethanol-safe Walbro pump motor
• New Walbro pre-filter
• Anodised billet outlet fitting to mate to the OE feed line
• Spare vent tube clip
• Two cotter pins for the float arm

Who is it for

If you are running a remap, hybrid turbos or plan to blend ethanol and want dependable low-pressure supply, this low side upgrade is the proven solution. Expect stable delivery for pulls, daily use and track days when paired with suitable tuning and maintenance.

Filter choices and running low on fuel

The standard kit includes a basic filter. Very low tank levels can cause starvation in hard use:

• For straight-line acceleration with less than one eighth of a tank, add the Fuel-It Option 1 filter upgrade.
• For road course work, long right-handers below half a tank may starve. For that use case, consider the standard Fuel-It Stage 2 with a basket configuration.

Compatibility

Direct replacement for E-chassis models with N54 or N55 turbo engines:

• 1 Series E82 Coupe and E88 Convertible
• 3 Series E90 Saloon and E90 LCI
• 3 Series E91 Touring and E91 LCI
• 3 Series E92 Coupe and E92 LCI
• 3 Series E93 Convertible and E93 LCI
• X1 E84

Popular applications include 1M, 135i and 335i across E82, E88, E90, E91, E92 and E93.
