Bavarian Autosport served the needs of BMW and MINI enthusiasts from 1974-2019. In 2019, ECS Tuning acquired the Bavarian Autosport brand, committing to continuing the tradition of excellence Bav Auto is known for. Over the years, Bav developed their own brand of parts, accessories and upgrades. A lot of these parts are engineered and built by OEMs (Original Equipment Manufacturers – companies who make original parts for BMW, MINI, and other European marques). Just as MINI, we work with a variety of manufacturers in Europe, Asia and North America. In many cases, we have sourced parts that are superior to Original Equipment.

A lot of time and resources have been put into developing and evaluating these products, as well as the companies who produce them. We stand behind every product we sell. If any product fails to meet our standards — or our customers' expectations — we won't sell it, and we're certainly not going to put the Bavarian Autosport name on it. In fact, we're so confident in the quality of these parts that we back every Bavarian Autosport brand part with a 2-year warranty.

If you encounter fuel pressure loss or starting issues despite a functioning engine and spark, consider replacing this unit—a common culprit in such situations. This fuel pressure pump with a level sensor, mounted inside the fuel tank, is the solution to restore your Mini's engine operation.

It's an effective method to diagnose a faulty rear fuel pump when there's a front High-Pressure Fuel Pump (HPFP) in place. Simply check if you can hear the rear fuel pump prime when opening the door or unlocking the car. Listen for a high-pitched, brief whining noise originating from the fuel tank, lasting only a couple of seconds. If absent, it indicates an issue with the primary rear fuel pump.

• Restores fuel pressure for proper engine function
• Designed for easy installation within the fuel tank
• Diagnostic feature helps identify faulty rear fuel pump

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.
