Product Details
- Holley Dominator In-Line Billet Fuel Pump features a dual-stage, twin-pump configuration engineered to supply the fuel demands of high-horsepower, turbocharged, supercharged, and nitrous-assisted builds
- Innovative twin-pump layout allows one pump to handle light-load cruising, with the second unit engaging during boost or nitrous activation for added capacity
- Designed to limit unnecessary fuel recirculation and minimize heat buildup, supporting improved hot fuel management and steady performance
- Precision-machined billet aluminum housing with high-flow O-ring inlet and outlet ports for secure, leak-resistant connections
- Compatible with both carbureted and EFI systems, suitable for 12-volt and higher-voltage racing applications, and adaptable for in-tank or inline mounting
- Compact, lightweight construction capable of delivering high operating pressures for gasoline, race fuel, and certain alternative fuel setups; not approved for aviation use
- Covered by a 90-Day Warranty
High output engines that rely on forced induction or nitrous require a fuel system that can keep pace without compromise. Whether you are driving to a weekend event or making an all out pass down the strip, steady fuel supply under varying demand is critical. The Holley Dominator In-Line Billet Fuel Pump is engineered to provide that added level of control for serious performance combinations.
Built around a patent pending dual pump configuration, this in-line unit allows one pump to operate during normal driving conditions, with the second pump activated when additional fuel volume is required under boost or nitrous engagement. Staging the secondary pump only when necessary helps limit excess fuel circulation and reduce heat buildup, contributing to improved consistency in demanding environments. The housing is precision machined from billet aluminum and features high flow O ring inlet and outlet ports. It is suitable for both carbureted and EFI systems and can be mounted externally or configured for in-tank use in custom setups to minimize plumbing. Designed to operate on standard 12 volt systems as well as higher voltage race applications, it supports high pressure requirements and is compatible with gasoline and race fuels, with select versions available for alternative fuel use. Its compact, lightweight design allows flexible installation on frame rails or in confined spaces.
Ideal for street and track vehicles alike, this twin pump assembly offers adaptability and added confidence when power demands increase. It is intended for high performance automotive use and not for aircraft applications. Backed by a 90-Day Warranty.
