Each pump option includes Genuine Walbro fuel pumps—either the 450 (F90000274), 525 (F90000285), or 535 (F90000295)—capable of flowing up to 350% more fuel than the factory fuel pump, with full E85 compliance. Each pump ships pre-assembled with an OEM connector for easy installation into the factory fuel pump top hat.

Important Considerations
While all bucketless fuel pumps offer .2gpm more than traditional bucket designs retaining the venturi, they should not be driven with tanks lower than ¼ full and are not suitable for road course racing. This limitation applies to all bucketless systems, not just ours. If you do not plan on road course racing and maintain responsible fuel levels during spirited driving, this is the perfect pump for you.
