4150 Fuel Bowl Screws (8)

The 4150 Fuel Bowl Screws set of 8 from Advanced Engine Design are precision fasteners designed specifically for high-performance carburetor applications, particularly with Holley 4150-series carburetors. These screws are essential for securing the fuel bowl to the main body, making them critical components in any fuel system assembly or carburetor rebuild.

Manufactured to exact specifications, these fasteners feature precise thread geometry and head design that ensures proper seating in the carburetor casting, preventing issues such as stripping or over-torquing. The set of 8 screws provides complete coverage for a standard bowl assembly, allowing for the replacement of worn or damaged fasteners during carburetor service. Proper installation requires careful torque application to achieve an even seal across the fuel bowl gasket surface, which is crucial for preventing fuel leaks.

Mechanics and engine builders working with both vintage and modern carbureted performance engines will find these replacement screws particularly beneficial, as they are often damaged during carburetor removal or disassembly. Ensuring you have quality OEM-spec replacement screws on hand can significantly enhance the reliability of your rebuilds and maintenance tasks.
