1.50in Hose Inlet/Outlet Adapter Fitting

The Aeromotive 1.50in Hose Inlet/Outlet Adapter Fitting (Part 11731) is an essential component for fuel system builders and engine swap enthusiasts who demand reliable flow control in high-performance applications. This adapter serves as a critical junction point between fuel lines and fuel system components, allowing you to consolidate or redirect fuel delivery with minimal pressure loss.

Whether you're upgrading a fuel pump system, installing a custom fuel rail, or adapting legacy components to modern fuel management systems, this fitting provides the standardized 1.50-inch port diameter required by many Aeromotive fuel delivery systems and aftermarket fuel system configurations. Built to Aeromotive's strict engineering standards, this hose adapter fitting features precision-engineered inlet and outlet ports designed to handle sustained fuel pressures in both carbureted and electronic fuel injection applications.

This adapter is ideal for fabricators working on street rods, race cars, and modern engine conversions. Weighing only 0.25 pounds with compact dimensions (2.9 x 2 x 4.95 inches), the fitting occupies minimal underhood space while providing the structural integrity necessary to maintain consistent fuel delivery without leakage or pressure degradation—critical factors when tuning carburetor mixture curves or managing EFI system fuel rail pressure.
