4150 Fuel Bowl Screws (8)

The 4150 Fuel Bowl Screws set of 8 from Advanced Engine Design is the OEM-grade fastener solution for Holley 4150 carburetor fuel bowl assembly and maintenance. Whether you're rebuilding a classic muscle car, restoring a vintage hot rod, or servicing a performance carburetor, these hex-head screws are essential hardware for securing the fuel bowl to the main body casting. Proper fuel bowl fastening is critical to preventing fuel leaks, maintaining fuel system integrity, and ensuring reliable carburetor operation across any engine platform.

Each 4150 Fuel Bowl Screw measures 2.5 inches in length and features a durable hex head design for secure socket or wrench engagement during installation and removal. Constructed from cadmium-plated steel, these fasteners deliver superior corrosion resistance in the fuel-rich environment of a carburetor bowl, preventing rust and degradation over extended storage or outdoor use. The included gaskets ensure proper sealing between the bowl and carburetor body, eliminating micro-leaks that can cause fuel seepage and poor engine performance. The cadmium plating provides excellent protection against fuel and moisture while maintaining consistent tensioning characteristics for repeatable, accurate bolt torque specifications.

Carburetor enthusiasts, engine builders, and restoration specialists rely on these screws for complete Holley 4150 fuel bowl service kits. The set of eight covers a full fuel bowl assembly with spare fasteners for lost or damaged hardware. Installation is straightforward: position the fuel bowl gaskets, align the bowl to the carburetor body, insert screws through the hex holes, and torque evenly in a cross pattern to manufacturer specifications—typically 3.5 to 5 foot-pounds for carburetor applications. Compatible with all Holley 4150 single and dual four-barrel configurations, these fasteners are the reliable choice for any mechanic or enthusiast maintaining or rebuilding classic fuel delivery systems.
