Overview
A piston pump driven by an electric motor moves fuel through this Dominator unit, which mounts in-line in the fuel system. The billet aluminum body carries a female O-ring port at each end.
Large ports and a high flow rate suit big carbureted or fuel-injected builds. The mount and plumbing are left to you, and the listing does not say how much pressure the pump should be regulated to.
Who it's for
Builders plumbing a custom fuel system will use the universal mount and AN ports. Anyone wanting a bolt-in tank module should buy a vehicle specific pump.
Pros and cons
- High flow at low pressure
- Large AN ports
- Works with gas and diesel
- Short ninety day warranty
- Fittings and filter sold separately
- Regulator not mentioned
Performance notes
Flow is rated at a specific low pressure, so output drops as pressure rises. An in-line pump pushes fuel from the tank, so it should be mounted low and near the tank for reliable supply.
