The Snow Performance SNF-52150 3-Pump Xtreme Fuel Hat is a high-output fuel system upgrade for 2014-2019 Chevrolet Corvette C7 applications. Designed to replace the factory fuel hat and bucket, this assembly supports three genuine TI Automotive (Walbro) 535 pumps and is engineered for maximum fuel flow. The Xtreme configuration can support more than 1,900 rear-wheel horsepower on E85 and up to 2,500 rear-wheel horsepower on gasoline, making it well suited for demanding high-performance and competition fuel systems. All three pumps must operate simultaneously; this configuration is not designed for staged pump operation or returnless fuel systems.
Snow Performance manufactures the fuel hat in the USA from 6061 billet aluminum with CNC-machined passages and a durable black anodized finish. The precision-machined body secures the pumps while Viton chemical-resistant O-rings provide a reliable, leak-resistant seal. By eliminating conventional rubber or plastic lines, T-fittings, and hose clamps inside the tank, the design helps simplify installation and reduce potential fuel-system failure points. The assembly is compatible with gasoline, ethanol, and gasoline-ethanol blends including E10, E85, and E98.
The SNF-52150 retains important factory fuel tank functions, including the original fuel level sending unit, EVAP system, filler neck, and saddle-tank transfer pump functionality when equipped. It features female 10AN ORB feed and 8AN ORB return ports, while optional 90-degree swivel adapter fittings are available separately for adapting to 10AN, 8AN, or 6AN fuel lines. This return-style fuel hat includes wiring harnesses for the fuel pumps and fuel level sending unit. The fuel level sending unit and fittings are not included. This product is not emissions-certified for street use and may require acknowledgment of applicable regulatory requirements.
