1/8" NPT To 1/4" Barb Straight Barb Hose Fittings (Electric Fuel Pump And Regulator)

These 1/8″ NPT to 1/4″ barbed hose fittings are designed for use in low-pressure fuel systems, making them ideal for connecting fuel lines to electric fuel pumps and fuel pressure regulators on classic Volkswagen setups. They provide a secure and reliable way to adapt small threaded ports to flexible fuel hose, ensuring safe and consistent fuel delivery.

Each fitting features a 1/8″ NPT tapered thread, allowing it to screw directly into fuel pumps, regulators, or carburettor fuel inlets where applicable. The tapered thread design ensures a tight, leak-resistant seal when used with appropriate fuel-safe thread sealant. The 1/4″ hose barb allows for easy connection to standard fuel hose, providing a firm grip that prevents leaks or hose disconnection under normal operating pressures.

These fittings are commonly used in upgraded fuel systems where an electric fuel pump replaces the original mechanical pump. In this setup, fuel is drawn from the tank, passed through the pump and regulator, and delivered to the carburettor(s). These barbed fittings act as the essential link between the threaded ports on the pump or regulator and the flexible fuel lines, helping maintain smooth and uninterrupted fuel flow.

For installation, you may also require 1/4″ fuel hose, suitable hose clamps, and fuel-resistant thread sealant. Depending on your setup, these may be used alongside inline fuel filters, regulators, or carburettor connections.

Sold as a pair, these fittings provide both inlet and outlet connections for your fuel system components.
