200 GPH Dominator In-Line Billet Fuel Pump (Dual Inlet)

Need to feed some serious horsepower? Have a nitrous or forced induction powerplant that also sees street duty? Holley's Dominator™ 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.

Features & Benefits
Twin pump design allows the use of both pumps simultaneously or independently - second pump can be activated on demand for power adders such as nitrous or boost

Fits: Carb or EFI Applications_x000D_ Supports up to 1800 EFI or 2100 Carb HP_x000D_ Compatible with Pump Gas*, Race Gas, Diesel or E85

Installation note: *Pump gas compatible for intermittent or under 90 degree ambient temperature use Pump gas use recommendations: • This pump is compatible with pump gas, but is not recommended for street driven vehicles where the ambient temperature is regularly above 90 degrees • For street driven vehicles in high temps with pump gas, Holley recommends part numbers 12-1200-2 or 12-1600-2 for optimum hot fuel handling• Proper fuel system engineering is critical for maximum performance. Please see Holley Fuel System Chart for information about proper installation of your fuel system.• To reduce fuel temperatures and vapor lock issues, it is recommended to operate these pumps using one pump for daily driving and low power levels and bring the second pump in with a pressure switch or other device when fuel flow needs increase. This will reduce heating of the fuel load by eliminating excess fuel circulating to the front of the vehicle, thru the fuel rails and back the tank. Will work with E-85! These pumps do not have an internal bypass. A bypass style regulator and return line are required.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.
