Fuel Pumps

Fuel Pumps: matching flow to the fuel your build actually needs

A fuel pump's job is simple to state and easy to get wrong: move enough fuel, at enough pressure, to keep the injectors fed under load. When you add boost, bigger injectors, or more diesel flow, the stock pump runs out of headroom and the engine leans out where it hurts most. The right upgrade restores that margin, whether it's an in-tank gas pump, a frame-mounted lift pump, or a high-pressure CP3/CP4 pump on a diesel. This category collects fuel pumps for both worlds under our Engine Components section.

What ThreePiece stocks

There are 372 fuel pumps here across 20 brands, priced from $19 to $2,732 - that's the current range for what's in stock, not a fixed price. The deepest catalogs are DeatschWerks (156 listings), AirDog (61), Aeromotive (43) and Walbro (40), with Fleece Performance, Fuelab, Radium Engineering, Exergy, Edelbrock and BBK filling out the range. Of these, 214 have specific fitment data, spanning model years from 1980 to 2025.

Coverage leans heavily on Ford, Chevrolet, Dodge, Nissan, Subaru, Mazda and Mitsubishi. Common applications include the Ford Mustang, Mazda Miata, Chevrolet Corvette, Subaru WRX, Nissan 240SX, Dodge Cummins and Chevrolet Duramax, along with Harley-Davidson and Polaris on the powersports side.

How to choose

Start with what the engine burns. For gas builds, a high-flow in-tank pump like the Aeromotive brushless spur gear pump with TVS controller or a drop-in module such as the DeatschWerks X2 dual-DW400 module keeps the plumbing tidy. A single Walbro-style pump covers most bolt-in upgrades at the lower end of the price range; a dual-pump module and controller is for builds that have outgrown one pump.

For diesel, the choice is between a lift pump and a high-pressure pump. High-pressure options like the Fleece PowerFlo 750 for 03-07 5.9L Cummins, the Exergy 10mm stroker CP3 for LBZ Duramax, and the Exergy stroker CP4.2 for 6.7L Power Stroke are matched to specific engines - buy by application, not by flow figure alone. A universal module like the Aeromotive TVS 90-degree brushless module suits custom setups where you're building the fuel system from scratch.

What else you need with it

A pump is one piece of the fuel system. Plan on Fittings and Adapters to connect the lines, and if you're raising flow you'll likely pair the pump with matched Fuel Injectors. Sealing work often means Gasket Kits, and a bigger electrical draw can push you toward a fresh battery from our Batteries category.

Fitment and ordering

Not every pump lists a vehicle, so confirm before you buy - call fitment help at 813-535-5801 or reach us through contact us. Every order ships free, and Affirm and Katapult financing is available on the higher-priced diesel and dual-pump setups.
