From high-demand fuel pump assemblies to direct-fit hangers, we’re trusted by enthusiasts and mechanics alike. Our lineup includes precision-engineered parts for Polaris, Harley-Davidson, KTM, and classic American icons like Chevy trucks, LS swap builds, and Fox Body Mustangs—each backed by durability, flow-tested reliability, and ethanol compatibility.
Polaris
Built for rugged terrain and long trail rides, our Polaris fuel pump assemblies and kits ensure off-road reliability. Whether you're replacing a stock unit or upgrading performance, QFS parts are engineered for OE fitment with high-flow capabilities. Designed to combat ethanol wear and trail vibration, our Polaris solutions keep your ATV or UTV running strong, mile after dusty mile.
Harley-Davidson
Our Harley-Davidson fuel pump replacement kits and assemblies are crafted for longevity and easy installation. Whether you're riding cross-country or cruising around town, QFS pumps deliver consistent fuel pressure and ethanol resistance. From Touring to Softail models, our parts match OE specs and are tested for road-ready performance under high mileage and heat. QFS is the first aftermarket fuel pump manufacturer to provide a full line of direct-fit, OE-quality fuel pump assemblies for a wide range of Harley-Davidson models.
KTM
KTM riders demand reliability on the trail and track, and that’s where QFS shines. Our KTM fuel pump kits and assemblies are precision-engineered for motocross and enduro performance, offering clean delivery, heat resistance, and fast installation. Whether you're replacing a worn-out OEM unit or upgrading for competition, our ethanol-safe pumps keep your engine dialed in and race-ready.
