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. Works with E-85 and is pump gas compatible for intermittent use or ambient temperatures under 90°F (for street driven vehicles in higher temps, Holley recommends the 12-1200 or 12-1600 pumps for optimum hot fuel handling). These pumps do not have an internal bypass — a bypass-style regulator and return line are required. 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.
FAQ
Is this pump compatible with E-85 or diesel?
Yes, this pump works with E-85, race gas, and diesel, and is pump-gas compatible for intermittent use.
Does this pump need an external regulator?
Yes, these pumps do not have an internal bypass, so a bypass-style regulator and return line are required.
What fittings are compatible with this pump?
Only contoured port fittings with an O-ring seal; standard conical seat fittings will block flow and cause pump failure.
How much horsepower can this pump support?
Up to 1800 HP naturally aspirated at 43 psi.
Is pump gas okay for street use?
Pump gas is compatible for intermittent use or ambient temperatures under 90°F; for regular street driving in higher heat, Holley recommends the 12-1200 or 12-1600 pumps instead.
