While all bucketless fuel pump flows .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 our bucketless system but is a disadvantage of all bucketless pump designs (or bucket designs which delete 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 this is the pump for you.

Note: To reach the advertised ability of these fuel pumps use of the Precision Raceworks in tank filter regulator assembly is required.

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.
