If your HDJ80 is approaching or past the 150,000km mark, 1HD-T injector lines are a manufacturer-specified replacement item. This isn’t a suggestion. There’s a real mechanical reason it’s on the service schedule.
Why 1HD-T Injector Lines Deteriorate
The steel lining inside each fuel line breaks down over time. As it does, fragments enter the fuel system and contaminate the injectors. On the 1HD-T, this internal contamination is a well-documented contributor to injector failure. Diesel injectors are not cheap to replace and the damage is often progressive. Replacing the lines at the correct service interval costs a fraction of what injector work does.
Genuine Toyota, Not a Substitute
These are Genuine Toyota 1HD-T injector lines. Not aftermarket. Not pattern parts. When a component sits this close to the injectors, genuine matters. The fitment is exact, the materials are to spec, and you get proper sealing at both ends straight out of the box.
This is a full set of six (6) lines, one per cylinder. If one line has 150,000km on it, they all do. Do the full job.
Suits Toyota LandCruiser 80 Series (HDJ80) fitted with the 1HD-T inline six diesel engine.
