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.  See it HERE.

** 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.
