These Dominator series fuel pumps are available in 375 gph and 525 gph models. They feature billet components, custom motors with sealed roller bearings, surfaces specially coated to minimize wear and friction, and weigh only 6.4 lbs. These fuel pumps are gasoline and alcohol compatible
These Red electric fuel pumps from Holley feature an improved design for street and strip applications, and a tumble-polished billet look with the distinctive red logo. These pumps have a 97 gph flow rate, draw only 2 amps, and have a maximum pressure of 7 psi with an externally accessible pressure relief valve. They weigh only 2.88 lbs., and include a mounting bracket
The needle and seat assemblies that are installed in Holley Performance carburetors can sufficiently control fuel pressure up to about 8 psi. If the fuel pump is putting out more than 8 psi, a regulator should be used to keep the fuel pressure within safe limits and avoid the possibility of flooding. Holley manufactures a number of regulators for most any need
It's always a good idea to place a safety switch in the circuit when installing an electric fuel pump. Holley has one that will ensure the electric pump will not work unless the engine has oil pressure. It will prevent the pump from running in a situation where the motor may stall with the ignition on. Wiring the switch through the starter solenoid circuit energizes the pump on engine start-up. After the engine is running, the switch continues to provide power to the pump as long as there is oil pressure to keep the switch turned on.
Holley fuel pump relay and harness kits are intended primarily for those applications running an electric pump. The long wire runs in these kinds of installations can sometimes result in a voltage drop at the electric pump. Installation of these kits are good insurance that the fuel pump will be receiving full voltage from the battery. These relays can be used with any electric fuel pump, as long as the current load is not above 30 Amps. They will work with 12, 16 and 24 Volt electrical systems and comes equipped with heavy gauge wires that provide extra current-carrying capacity with minimal voltage loss. A 30 Amp relay is included with a relay socket wired with long leads specifically designed to reduce the number of splices required. Quality insulated crimp connectors are provided to make the necessary splices, where required. Detailed instructions are included.
This high output electric fuel pump is designed to provide the additional fuel required when other engine modifications such as camshaft, headers, and larger injectors are installed. It is designed for easy installation, and includes all parts.
Holley Street Performance mechanical fuel pumps are designed to work with stock or mildly modified engines, and deliver free-flow outputs from 80 to 130 gph. Their body castings can be rotated 360 degrees to ease mounting in difficult places, and they have large orifices for high flow rates. Most have 3/8 in. NPT inlets and outlets. These pumps are not compatible with methanol or alcohol fuels, and should not be used with fuel injection systems. A fuel pressure regulator is required for 130 gph versions.
These Black electric fuel pumps from Holley feature an improved design for street and strip applications, a new lower housing casting for enhanced fuel flow, and a tumble-polished billet look with the distinctive black logo. These pumps have a 140 gph flow rate, only draw 4 amps, and have a maximum pressure of 14 psi with an externally accessible pressure relief valve. They weigh only 3 lbs., and include a mounting bracket. These pumps are compatible with alcohol or methanol fuels.
