Fuel Pump Systems
Fuel Pump Systems: complete kits to feed a hungrier engine
A fuel pump system is the assembly that moves fuel from the tank to the injectors at the pressure and volume your engine actually demands. When you add boost, more injector flow, or bigger power targets, the factory pump usually runs out of headroom and starts leaning out under load. Fuel pump systems solve that by packaging a high-flow pump with the mounting hardware, hanger or drop-in assembly, and wiring needed to make it a job you finish rather than a shopping list you assemble. The complete kits sold here are built around a specific install so the pump seats correctly and delivers its rated flow without a fabrication project.
What ThreePiece stocks
This category currently lists 4 products from 2 brands: standalone fuel pumps live in their own category, while these are the full systems. The brands are Aeromotive and Injector Dynamics. Prices run from $931 to $3,261, which is the current range for what is in stock, not a fixed quote. At the top sits the Injector Dynamics 1100lph system with BPC100 and TI E5LM pump at $3,261 for high-target builds. Aeromotive covers the truck side with the 450 Dual Drop-In Phantom system at $1,508 and the 340 Dual Drop-In Phantom system at $1,056.
How to choose
The split here is straightforward. The Aeromotive drop-in systems are application-specific and vehicle-ready, so if you are working on a covered platform the install is largely bolt-in. Within that line, the 340 and 450 versions differ in flow capacity, so pick based on your power target rather than price alone. The Injector Dynamics system is a higher-capacity, higher-priced package aimed at builds that need substantially more fuel and are willing to pay for the pump and controller combination. If your target is modest, the lower-flow option is the honest choice; if you are chasing a big number, undersizing the pump is the mistake to avoid.
What else you need with it
Plumbing a fuel system rarely ends at the pump. You will likely need fittings and adapters to connect lines and match thread sizes. If the engine is apart for the work, browse the related gasket kits and head gaskets, and keep an eye on supporting hardware like batteries for the electrical load a high-flow pump can add. Everything sits under the broader Engine Components section.
