Review SPEED FX 8an Black Dual Inlet Holley 4150 Carbs Fuel Line Fitting

The FX 575115BK 8-AN Dual Inlet Holley 4150 Carburetor Fuel Line Fitting is an essential component for connecting your fuel lines to your Holley 4150 carburetor. This fitting is specifically designed for use with dual inlet carburetors and features an 8-AN (8-Annex) thread size, making it a popular choice among hot rods and performance engines.

The body of the fitting is made from high-quality brass, which offers excellent resistance to corrosion and ensures a secure, leak-free connection.

Each inlet port is equipped with a 3/8-inch NPT (National Pipe Thread) thread, which is a standard size for many fuel lines and fittings.

The O-ring seal on the fitting is made of high-quality, Viton material, which is known for its excellent sealing properties and ability to withstand high fuel pressures. The O-ring also ensures a tight, leak-free seal between the fitting and the carburetor or fuel line.

The FX 575115BK 8-AN Dual Inlet Holley 4150 Carburetor Fuel Line Fitting is a crucial part of your fuel system and requires careful installation to ensure optimal performance. Be sure to clean and degrease the threads on your carburetor and fuel lines before installation to ensure a proper seal. Use a torque wrench to tighten the fitting to the recommended torque specification to avoid damaging the threads or O-ring.

In summary, the FX 575115BK 8-AN Dual Inlet Holley 4150 Carburetor Fuel Line Fitting is a high-quality, durable component that provides a reliable connection between your fuel lines and carburetor.
