Holley 12-802-1 Fuel Pump: The Complete Guide to the 110 GPH Blue Electric Fuel Pump

If you are looking for a reliable, high-flow external fuel pump for a carbureted street or strip engine, the Holley 12-802-1 Blue Electric Fuel Pump is the best value option on the market today. This pump delivers 110 GPH free flow, includes a fuel pressure regulator in the box, draws only 3 amps, and is proven to support up to 600-700 horsepower on carbureted applications and around 500 horsepower on low-boost EFI setups . It is a direct upgrade from the smaller Holley Red pump, and the included regulator saves you $50-80 compared to buying components separately . For anyone building a high-performance gasoline engine that needs consistent, pulsation-free fuel delivery, the Holley 12-802-1 is the pump to start with.

What Makes the Holley 12-802-1 Different?

1. Flow Rate and Pressure Specifications

The Holley 12-802-1 is rated at 110 GPH (416 LPH) free flow, and it flows 88 GPH at 9 PSI . Maximum pressure is capped at 14 PSI . The pump includes a built-in pressure relief valve and comes with the Holley 12-803 fuel pressure regulator, so you can dial in the exact pressure your carburetor or low-boost EFI system needs .

2. Low Amp Draw

One of the standout features of this pump is its 3-amp current draw . This is low enough that you can run it on most factory wiring without needing a full electrical system upgrade. However, Holley recommends using a relay kit (P/N 12-753) and a 7.5-amp fuse for best performance and safety .

3. Design and Build Quality

The pump features a tumble-polished billet look with a distinctive blue logo on a silver aluminum housing . It weighs only 3 pounds, making it easy to mount in tight engine bays . The lower housing casting has been redesigned for enhanced fuel flow, and the rotor/vane design is proven to tolerate contaminated fuel better than some other pump types .

4. Inlet and Outlet Ports

The pump uses 3/8-inch NPT female threads on both the inlet and outlet . This is a standard size that works with most carbureted fuel systems and aftermarket fuel line kits.

What Engine Applications Does This Pump Work For?

Carbureted Engines (600-700 HP)

The Holley 12-802-1 is designed and recommended for carbureted applications . It is a perfect match for big-block Chevys, Ford FE engines, Mopar big-blocks, and any high-horsepower V8 running a carburetor. Real-world testing shows this pump can support 600-700 horsepower on a carbureted setup .

Low-Boost EFI (Up to 500 HP)

While the pump is not designed for full fuel injection systems, it can work on low-boost EFI setups up to about 500 horsepower . If you are running a factory-style return-style regulator, the included regulator is redundant, and you might consider the Holley 12-801-1 Red pump instead to save money .

Marine and Non-Automotive Uses

This pump is a popular choice for marine engine conversions, diesel pushers, and other non-automotive applications . The consistent fuel delivery, low amp draw, and included regulator make it easy to adapt to non-standard installations .

Installation Tips and Best Practices

1. Mount the Pump Below the Fuel Level

For reliable gravity feed on the inlet side, the pump should be mounted below the fuel level of the tank . This prevents the pump from having to pull fuel uphill, which can cause cavitation and premature wear.

2. Use a Relay Kit

Holley strongly recommends using a relay kit (P/N 12-753) along with a 7.5-amp fuse . This protects the electrical system and ensures the pump gets full voltage during operation.

3. Use a Safety Shut-Off Switch

Holley strongly recommends installing a safety shut-off switch (P/N 12-810) . In the event of an accident or engine stall, this switch will cut power to the pump, preventing fuel from being pumped into a hot engine bay.

4. Fuel Compatibility

This pump is designed for gasoline only. It is not compatible with alcohol or methanol fuels . For E85 applications, look at pumps from AEM or Aeromotive .
