BMW E9x/E8x Bucketed Performance Fuel Pump by Precision Raceworks

The Precision Raceworks E9x / E8x LOW PRESSURE BUCKETED FUEL PUMPS are designed for customers looking to run all blends of E85. All pump options below include Genuine Walbro 450 (F90000274), Walbro 525 (F90000285), or Walbro 535 (F90000295) fuel pump(s) capable of flowing up to 350% more fuel than the factory fuel pump and all options are 100% E85 compliant.

How is this different from our Non-Modular bucketed fuel pump?
Simply put, this kit is upgradeable from a stage 2 to a stage 3, and all the way up to the stage 4!  If you are currently just starting on building your E9x or E8x and don't want to buy the pump you need for the future now, you can purchase what you need now, and then upgrade it with a pump upgrade module! If you are looking for a lower cost solution that still retains the factory Venturi's, then consider our Non-Modular Fuel Pump.

While all bucketless fuel pumps flow .2gpm more than a bucket design that retains the venturi it comes at a cost. Bucketless pumps should not be driven on tanks lower than ¼ full and should not be used for road course racing. This is not a disadvantage of only bucketless designs but also a disadvantage for any bucket design which deletes the venturi. If you do not plan on road course racing (not street racing) and are responsible at maintaining ¼ tank of fuel during spirited driving bucketless pumps can be a cheaper alternative for you.

* To reach the advertised ability of these fuel pumps, the use of the Precision Raceworks In-Tank filter regulator assembly is required.

** Some European Spec vehicles may require re-use of top hat due to differences in emissions requirements.

This is a true plug and play solution that anyone can install in their home garage and start taking advantage of the benefits right away.
