Complete the service — add the Genuine Injector & Rocker Cover Fitting Kit:

If you're replacing injector lines, you should be replacing the seals too. This 30-piece genuine kit covers every seal, washer and fastener required for the job.

• Toyota Hilux 1KD-FTV — 08/2006 to 2015 (with EGR cooler)
• Toyota Prado 1KD-FTV — (with EGR cooler)

⚠️ Early 1KD engines without an EGR cooler use a different set. If your Hilux is pre-08/2006, see the Euro 3 injector line kit here.

• Keep all injector and rail ports capped until installation
• Do not bend or reform hard lines
• Follow Toyota torque specs and tightening sequence
• Inspect carefully for leaks on first start-up

⚠️ Professional installation recommended — common rail systems operate at extremely high pressure. Any contamination or sealing issue at these pressures is serious.

• Diesel smell in engine bay
• Hard starting or rough idle
• Weeping around injector or rail fittings
• Repeat sealing issues after injector replacement
• Rail pressure faults or inconsistent fuel delivery

Do these fit all 1KD engines?
No. This kit suits Hilux and Prado 1KD engines fitted with an EGR cooler (non-DPF) — generally 08/2006 onwards. Early non-EGR engines need a different set. Euro 3 kit available here.

Are these genuine Toyota parts?
Yes — every line is genuine Toyota, listed by OEM part number. Not aftermarket copies.

Should I replace injector lines when fitting new injectors?
Strongly recommended. Old lines can harbour debris and the ferrule seats degrade over time — reusing them risks micro-leaks and contamination in your new injectors. Do it once, do it right.

Do I need to replace the seals at the same time?
Yes — if you're pulling the injectors out, replace the seals. The 30-piece Genuine Injector & Rocker Cover Fitting Kit (button above) covers everything you need.
