Motion Pro 12-0046 Inline Fuel Valve Shut Cut Off 1/4" Barb X 5/16" Barb

OVERVIEW

This inline fuel valve provides a reliable manual shut-off point for precise fuel flow control during maintenance, seasonal storage, or engine tuning. Engineered as a straightforward cut-off switch, it isolates the fuel pathway without disrupting primary pump or carburetor architecture. Built for motorcycles, ATVs, and utility machines relying on lighter powertrains, it delivers secure hose integration and predictable fuel isolation.

ENGINEERING & PERFORMANCE

The valve maintains steady fuel passage when fully open and seals completely when closed, preventing drips, vapor migration, or accidental drain-down during transport. Its direct-inline configuration mounts straight between existing hose runs, preserving factory routing angles and clearing frame obstructions. Rated for optimal operation on displacements up to 200cc, the design keeps low-pressure fuel delivery consistent while offering firm mechanical indexing for repeatable open-and-shut cycling.

WHY RIDERS CHOOSE THIS

Riders select this inline cut-off because it removes spill risk and guesswork when transferring batteries, draining sumps, or trailering machinery across short distances. The straight-barb layout mates cleanly with standard rubber fuel lines, while the positive-action lever prevents slow drips that plague worn stopcocks. By delivering immediate fuel isolation at operating pressures, the valve protects downstream components from priming leaks and keeps workshop floors dry. Its compact footprint slides into tight engine compartments without interfering with exhaust routing or heat sources.
