Fuel Injector Adapter - 14mm 1/2 to 3/4 Length

Overview

Transform your shorter fuel injectors into full-length units with this precision-machined 14mm adapter. Essential for retrofitting compact injectors into standard fuel rails, this adapter extends 1/2 length (34mm) injectors to 3/4 length (48mm) whilst maintaining proper sealing and flow characteristics.

Technical Specifications

• Part Number: HT-080005
• O-Ring Size: 14mm top seal
• Length Extension: 34mm to 48mm (1/2 to 3/4 length)
• Material: Machined aluminium construction
• Finish: Hard anodised for corrosion resistance

Why You Need This

When building high-performance engines or converting to EFI, you'll often find the perfect injectors for your flow requirements come in the wrong physical size for your fuel rail. This is particularly common with LS swap builds using factory truck rails, RB25/26 conversions, or when upgrading from lower-capacity factory injectors to high-flow units. The compact 1/2 length injectors often offer better value and availability, but won't seal properly in standard 3/4 length fuel rail bores.

Without proper length matching, you risk fuel leaks, inconsistent spray patterns, and potential fire hazards. This adapter eliminates the compromise between injector specification and physical fitment. We see this constantly in our workshop when customers want to run specific injectors like ID1050x or Bosch EV14 compact units in applications designed for longer injectors. The included retaining clip ensures secure installation, whilst the filter basket provides additional fuel filtration at the injector inlet.

ECU & System Compatibility

Universal fitment for any fuel system using 14mm O-ring sealed injectors. Works perfectly with Haltech Elite and Nexus ECU installations where injector selection is based on flow requirements rather than physical constraints. Compatible with all major injector brands including Injector Dynamics, Bosch, Siemens, and OEM units.
