Squirter Screw-High Flow Gasoline

The Squirter Screw-High Flow Gasoline from MOROSO is a precision carburetor component engineered for fuel system optimization in high-performance gasoline engines. This specialized screw addresses flow restriction at the carburetor's discharge circuit, making it essential for tuners and mechanics seeking to maximize fuel delivery and engine responsiveness. Whether you're building a street performance engine, restoring a classic muscle car, or fine-tuning a naturally aspirated powerplant, this high-flow design eliminates bottlenecks that restrict fuel atomization and combustion efficiency.

The high-flow geometry of this screw increases the effective orifice diameter compared to OEM restrictors, allowing more precise fuel metering across the engine's operating range. By reducing pressure drop through the carburetor's fuel circuit, the screw enables richer fuel delivery during acceleration and wide-open throttle conditions, improving combustion quality and engine response. The design is compatible with most Holley and conventional four-barrel carburetors, and its compact, lightweight construction (0.03 lbs) integrates seamlessly into existing fuel systems without modification to base gaskets or mounting hardware.

This component benefits carburetor enthusiasts, vintage drag racing builders, and street rod fabricators who demand precise fuel control and repeatability. Installation requires basic carburetor disassembly and takes minutes with standard hand tools—no special equipment needed. The Squirter Screw-High Flow Gasoline works best in applications where stock fuel delivery limits power output or throttle response; it's particularly effective in carbureted engines running larger cam profiles, higher compression ratios, or modified intake manifolds where fuel atomization becomes critical to performance.
