Fuel Injector Adapter - 14mm 1/2 to Full Length

Overview

Transform your short-body fuel injectors into full-length fitments with this precision-machined 14mm adapter. Essential for running high-flow half-length injectors in standard fuel rails, eliminating the need for expensive rail modifications or custom fabrication.

Technical Specifications

• Part Number: HT-080006
• Injector Compatibility: 14mm top O-ring, 1/2 length (34mm) injectors
• Rail Fitment: 14mm O-ring bore fuel rails
• Extended Length: Converts to full-size 60mm equivalent
• Material: Anodised aluminium construction

Why You Need This

Half-length injectors like the popular ID1050X or DW400 series offer excellent flow characteristics and precise spray patterns, but their compact 34mm body creates fitment headaches in standard fuel rails designed for 60mm injectors. Without proper spacing, short injectors sit too high in the rail, creating poor sealing, inconsistent fuel delivery, and potential lean-out conditions that'll destroy your engine faster than you can say "melted piston".

This adapter solves the problem elegantly, positioning your high-performance injectors at the correct depth for optimal spray targeting into the intake port. We see this constantly on LS swap builds running aftermarket rails, RB25/26 setups upgrading from stock restrictive injectors, and 2JZ builds where owners want to retain OEM rail aesthetics whilst running serious flow. The included filter basket provides additional fuel filtration right at the injector, whilst the retaining clip ensures secure fitment even under high rail pressures typical in forced induction applications.

ECU & System Compatibility

Universal fitment for any fuel system running 14mm top-feed injectors. Commonly used with Haltech Elite and Nexus ECU installations where precise injector sizing is critical for accurate fuelling maps. The adapter maintains proper injector impedance and flow characteristics, ensuring your Haltech ECU can deliver accurate fuel timing and pulse width calculations.
