QFS Air Pressure Regulator for Sea-Doo GTX/RX DI (2000-2003), 3D DI (2006-2007), XP DI (2003-2004), Sportster DI (2004-2006), and LRV DI (2002-2003), Replaces 275500463

Optimizing your PWC’s air pressure regulator is essential for maintaining the precise boost and fuel-rail pressure required for high-performance watercraft engines. Engineered to withstand the demanding marine environment, this regulator ensures a consistent air-to-fuel ratio, preventing lean conditions that can lead to engine overheating or hesitation during rapid acceleration. Built from corrosion-resistant materials to defy saltwater wear and high-vibration use, it serves as a direct, drop-in replacement that restores smooth idling and peak throttle response. By maintaining stable pneumatic output, this regulator protects your engine’s internal components and ensures reliable, high-speed performance every time you hit the water. This particular air pressure regulator was designed to fit various Sea-Doo personal watercraft and Sport Boats: 2006-2007 Sea-Doo 3D DI 2000-2003 Sea-Doo GTX DI 2002-2003 Sea-Doo LRV DI 2000-2003 Sea-Doo RX DI 2004-2006 Sea-Doo Sportster DI 2003-2004 Sea-Doo XP DI

• HFP-PR25 is engineered as a direct replacement for the air rail regulator, replacing OE # 275500463, specifically designed for Sea-Doo Direct Injection personal watercraft models; compatible with 2006-2007 3D DI, 2000-2003 GTX DI, 2002-2003 LRV DI, 2000-2003 RX DI, 2004-2006 Sportster DI, and 2003-2004 XP DI
• Precision-calibrated to maintain a high-tension 580KPA (84 psi), providing the exact air pressure required for the Orbital DI system to properly atomize fuel into the combustion chamber
• This air regulator restores engine performance to resolve common DI issues: engine bogging, "limp mode" activation, fouled plugs, and hard starting caused by air rail pressure loss
• Constructed from marine-grade, corrosion-resistant materials to withstand the harsh salt and freshwater environments, preventing the internal spring fatigue common in aging factory units
• Ride with confidence – Guaranteed – As a US-based small business, we know that Sea-Doo DI systems require absolute precision. Backed by our lifetime warranty, we stand by our products and our community
