🧩 Product Overview

OEM genuine Isuzu injector fuel lines engineered specifically for 2012-2016 models using injector 095000-8340. OEM design maintains correct sealing integrity and injector reliability.

🔧 What Else You'll Need

If you're replacing injector lines, you'll need copper washers for proper sealing:

Essential — Injector Washer Kit:

Copper washers for proper sealing. Never reuse old washers — they won't seal properly the second time.

🛒 Add Injector Washer Kit

💡 Pro Tip: Avoid bending or re-shaping injector lines during servicing, as this can weaken the pipe and lead to cracks or leaks once reinstalled.

⏱️ When to Replace Injector Fuel Lines

Knowing when to replace injector fuel lines is critical to maintaining engine performance and injector longevity.

  • Visible cracks, leaks or bulging in the lines
  • Fuel contamination or unexplained injector damage
  • Injector replacement or major fuel system service
  • High-kilometre vehicles (typically 120,000–150,000 km)

Over time, the internal steel surface of high-pressure fuel lines can degrade. Microscopic particles may then be carried into the injectors under extreme rail pressure, potentially causing internal damage.

Avoid bending or re-shaping injector lines during servicing (such as rocker cover removal), as this can weaken the pipe and lead to cracks or leaks once reinstalled.
