Holley set the bar in 2011 with the release of the HP and Dominator in-line fuel pumps. In 2015, Holley has raised the bar again with the introduction of the VR1 and VR2 Brushless in-line fuel pumps. Featuring brushless pump technology and a twin screw rotor design, the VR1 and VR2 in-line fuel pumps are capable of high pressures and flows while maintaining a low amperage draw and quiet performance. Designed to work on high boosted race cars as well as your daily driven weekend endurance car, these pumps work with gasoline, methanol, and E-85* and can maintain pressures of 130 PSI and up to 335 GPH flow**. Fueled by TI Automotive. The pumps include a 2 step controller for pump speed control. The pumps can be ran in one of two different speeds. A low speed control for low fuel consumption requirements or at full speed for high fuel consumption requirements. The VR2 includes (2) controllers for precise control of both pumps independently of each other. Both the VR1 and VR2 pumps are proven for 18.5V compatibility. **At 13.8V * Overall pump dimensions: 9.5" Long; 4.75" Wide; 2.75" Tall
