3/8 ID Fuel Hose 25ft SAE 30 R7KX

The MOROSO 3/8 ID Fuel Hose 25ft SAE 30 R7KX is a purpose-built rubber fuel delivery line engineered for high-performance automotive fuel systems. With a 3/8-inch inner diameter and 25-foot length, this hose meets SAE 30 specifications and provides reliable fuel transfer in both street and competition applications where fuel system integrity is non-negotiable.

SAE 30 rating indicates this fuel hose is rated for fuel compatibility and pressure resistance within automotive fuel system parameters. The 3/8-inch ID accommodates standard fuel pump discharge lines and carbureted or fuel-injected engine configurations. The 25-foot bulk length allows users to cut, route, and terminate fuel lines according to engine bay layout and fuel cell positioning. Black rubber construction resists UV degradation and provides flexibility across engine compartment temperature swings typical in performance builds.

This hose is suited for engine builders, restoration shops, and performance enthusiasts fabricating custom fuel systems. Common applications include fuel delivery from tank to carburetors, electric fuel pumps, fuel pressure regulators, and distribution blocks. Users installing high-flow fuel systems, swapping engines, or converting carbureted engines to fuel injection frequently source bulk fuel line to eliminate mid-line connectors and reduce leak points in the fuel path.

MOROSO is recognized in the performance automotive industry for fuel system components. Sourcing fuel hose by length and inner diameter specification ensures compatibility with existing fuel pump discharge ports, carburetor inlet fittings, and fuel rail adapters. Proper hose sizing and SAE compliance reduce pressure loss and fuel vapor permeation.
