* Overall pump dimensions: 9.5" Long; 4.75" Wide; 2.75" Tall

• Capable of 130 PSI while providing significant flow for forced induction applications where belt driven pumps are normally used.
• Unlike other pumps, the VR Series are built for continuous duty if needed.
• The dual pump models are designed for endurance racing where both pumps are used or one can be a reserve pump.
• Billet aluminum construction for durability and good looks
• Features a single 16 AN O-ring inlet and a single 10 AN O-ring outlet
• High flow and high pressure with low amperage draw
• Can be fully submerged in the fuel cell or chassis mounted
• Maximum amp draw of 38 AMPS for the VR2
• Holley also offers a complete line of fuel filters and fuel pressure regulators that are designed to work as a system with these pumps

Information:

*Compatible for methanol and E85 for competitive drag race use only- when draining and flushing after each race event * These pumps are not for use on aircraft of any type. * Overall pump dimensions: 9.5" Long; 4.75" Wide; 2.75" Tall These pumps do not have an internal bypass. A bypass style regulator and return line are required. HP estimates are based on gasoline. Estimates calculated at 18.5V and at .5 BSFC NA and .65 BSFC FI. Individual systems will vary based on fuel system design, regulator type, fuel cell location, launch G's, etc. Proper fuel system engineering is critical for maximum performance. This pump is not designed to use a standard conical seat style union in the inlet or outlet of the pump. Example: Part # AT981510ERL. Use of this style fitting will block flow and WILL lead to poor performance and pump failure. The ONLY correct fitting to use is a contoured port fitting with an O-ring seal such as :Part # AT985010ERL.

Application Summary:

Year	Make/Model
Holley	set the bar in 2011 with the release of the HP and Dominator in-line fuel pumps. In 2015
Holley	has annihilated the bar with the introduction of the Ultra HP and Dominator Brushless in-line fuel pumps. Featuring brushless pump technology and a twin screw rotor design
the	Ultra HP and Dominator 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 Drag Week car
these	pumps work with gasoline
and	E-85 (Compatible for methanol and E85 for competitive drag race use only-when draining and flushing after each race event) and can maintain pressures of 130 PSI and up to 323 GPH flow . 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 Ultra Dominator includes (2) controllers for precise control of both pumps independently of each other. Both the Ultra HP and Ultra Dominator pumps are proven for 18.5V compatibility. At 13.8V
