Holley 12-1600 160 GPH Dominator In-Line Billet Fuel Pump Street/strip CARB or EFI Applications Supports Up to 1600 EFI or 1800

Need to feed some serious horsepower? Have a nitrous or forced induction powerplant that also sees street duty?

Holley's DominatorTM in-line fuel pumps are the answer! The patent pending twin pump design allows you to use one pump for cruising and both pumps when you activate the nitrous switch or start building boost!

By staging the second pump, you eliminate the unnecessary recirculating and heating of extra fuel which can lead to poor performance and hot fuel issues. As an added benefit for the hard core enthusiasts that run events like Hot Rod Power Tour and the Baja 1000, the extra pump offers the peace of mind that you will always finish what you start!

For hard core race vehicles, both pumps can be wired for full time duty to get maximum performance and are proven with 18.5 volt compatibility at pressures up to 80 psi. Holley engineers have designed 12-1600 to feature improved hot fuel handling capabilities.

It was designed to greatly reduce the negative effects of heated fuel now common with many of today's pump gas blends. It is available for use with pump gas or race gas.

If you are using E-85 or diesel, no need to worry, Holley has still got you covered with the 12-1800 Dominator Fuel Pump. At only 5.1 lbs, they weigh half a pound less than competitive 1000+ horsepower pumps yet have twice the features!
