Overview Transform your fuel delivery setup with this precision-engineered adapter that converts compact 1/2 length injectors into full-length fitments for 10.5mm O-ring fuel rails . Essential for modern high-flow injector upgrades on classic platforms or when space constraints demand shorter injectors whilst maintaining OEM rail compatibility. Technical Specifications Part Number: HT-080000 Injector Compatibility: 1/2 length (34mm) with 14mm top O-ring Rail Fitment: 10.5mm O-ring bore fuel rails Extended Length: Converts to full 60mm injector profile Material: Precision-machined aluminium construction Why You Need This Modern high-flow injectors often come in compact 1/2 length designs for packaging efficiency, but your fuel rail expects full-length injectors. Without proper adaptation, you'll face sealing issues, incorrect spray patterns, or simply won't achieve secure fitment. This adapter bridges that gap perfectly, maintaining proper injector positioning and sealing integrity whilst allowing you to run the latest short-body injectors in traditional setups. We see this adapter frequently on LS swap builds where customers want to retain factory fuel rails but upgrade to modern ID1300X or similar compact injectors. It's also essential for RB25/RB26 builds running aftermarket rails with 10.5mm bores, Toyota 2JZ applications, and classic EFI conversions where rail bore sizes don't match modern injector specifications. The included filter basket provides additional fuel filtration whilst the retaining clip ensures secure installation under high fuel pressures and engine vibration. ECU & System Compatibility Works with any fuel injection system regardless of ECU brand. Particularly relevant for Haltech Elite and Nexus builds where precise injector control demands proper mechanical fitment and sealing. Compatible with the full Haltech Elite 550/750/1000/1500/2000/2500 range, Nexus R3/R5, and Platinum series ECUs when upgrading injectors as part of your engine management conversion.
