Fleece Performance Engineering has grown from a small Indiana operation into one of the most respected names in high-performance diesel upgrades, with a product catalog built specifically around the Duramax and Cummins common rail diesel platforms that dominate the high-horsepower diesel community. Founded by brothers Brayden and Chase Fleece in a rural west-central Indiana pole barn, the company established itself as a technology leader in common rail injection systems within five years, developing the Cheetah turbocharger line and the TurboBrake electronic exhaust brake that have become standard references for what diesel performance engineering can achieve. Fleece operates from an 18,750-square-foot Brownsburg, Indiana facility capable of in-house design, manufacturing, assembly, and testing, placing them among the high-output diesel specialists who supply race teams and serious street performance builds. This collection covers Fleece Performance's full range of Duramax and Cummi...

A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential. Popular Upgrades Top-selling fuel delivery components include Aeromotive Phantom in-tank fuel pump kits that retrofit into factory tanks without custom fa...

Fuel pump fitment kits provide all the hardware and sealing components needed to properly install a replacement or upgraded in-tank fuel pump module, eliminating the frustration of sourcing individual lock rings, O-ring seals, strainer socks, and wiring pigtails separately. On high-mileage vehicles, the original pump module seals harden and crack, causing fuel vapor leaks that trigger EVAP system faults even after the pump itself has been replaced with a new unit. Fitment kits that include a new O-ring, sender float arm, and locking ring allow a complete restoration of the fuel module assembly rather than just the pump element, producing a more reliable repair with a longer service interval. For performance upgrades, complete drop-in fitment kits from Aeromotive and Walbro include pre-assembled pump modules sized for the factory tank opening to simplify the upgrade process.
