About bucketed vs. bucketless design

While bucketless fuel pumps can flow a bit 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.

*To reach the advertised ability of these fuel pumps 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.

These kits offer a true plug and play solution that anyone can install in their home garage and start enjoying the benefits right away.
