Drag Specialties DS-390217 Fuel Petcock 90° Chrome 3/8" NPT High-Flow Valve w/ Screen

OVERVIEW

The Drag Specialties DS-390217 fuel petcock regulates precise fuel delivery while maintaining stable engine operation across varying throttle loads. This late-style 90-degree valve employs a chrome-plated metal construction engineered specifically for Harley-style motorcycle fuel tanks that require standard 3/8-inch NPT port threading. Designed as a direct replacement or targeted upgrade, it integrates cleanly into modern cruiser and custom builder setups without modification.

ENGINEERING & PERFORMANCE

The unobstructed internal passageway eliminates restriction, ensuring consistent fuel volume reaches the carburetor or injector assembly during high-demand riding conditions. A durable chrome-coated exterior guards against road salt, moisture exposure, and UV degradation, while the precision-machined lever pivot prevents sticking or cross-threading over thousands of cycles. The intuitive three-position turret provides instant access to ON, OFF, and RESERVE states, allowing riders to manage residual tank capacity safely after long rides.

WHY RIDERS CHOOSE THIS

Motorcyclists replace worn OEM petcocks to stop slow leaks, hardened diaphragms, and sticky selectors that disrupt idle stability or cause fuel starvation. The reinforced chrome shell maintains crisp lever action even after years of vibration and thermal cycling, while the integrated screen extends service life by blocking abrasive particles from reaching sensitive carburetor jets or fuel filters. Its accurate 90-degree mounting orientation lines up naturally with aftermarket rubber lines and brake-line-style hardware, saving time during frame-up restorations or trail-ready builds. Riders prioritize this component because it restores factory-level fuel metering reliability without compromising the authentic finish expected on heritage-style motorcycles.
