Holley's Dominator in-line fuel pumps are built to feed serious horsepower for nitrous or forced-induction combinations that also see street duty. The patent-pending twin-pump design lets you run one pump for cruising and both pumps once nitrous or boost is activated, reducing unnecessary fuel recirculation and heat.

Compact at 7.66" long x 5" wide x 2.5" tall, and fully submersible for in-tank or custom applications. These pumps do not have an internal bypass — a bypass-style regulator and return line are required. Not for use with methanol, E-85, or diesel. Requires a contoured port fitting with O-ring seal (such as P/N AT985010ERL); standard conical seat fittings (such as P/N AT981510ERL) will block flow and cause pump failure.
