Genuine Isuzu | D-MAX, Rodeo RA7 & Colorado RC | Set of 4
A four-piece high-pressure injector line set for early 4JJ1 common rail engines. Each pipe is cylinder-specific and pre-bent to factory routing, so it goes back in without persuasion. The right time to fit these is while the injectors are already out.

Fitment
- Isuzu D-MAX 4JJ1 - up to 2013, pre-DPF
- Holden Rodeo RA7 4JJ1 - up to 2012, pre-DPF
- Holden Colorado RC 4JJ1 - up to 2012, pre-DPF
Suits injectors: Denso 095000-6980, and some 095000-8340 / 8-98106693-2 around 2012 to 2013.
Two sets exist: if your D-MAX or MU-X is 2012 to 2016 running 095000-8340 injectors, you likely need the 2012 to 2016 line set instead.
*Guide only*: Leave your rego and state or VIN in the order notes and we will confirm before dispatch.
When to Replace Injector Lines
- Visible cracks, leaks or bulging in a line
- Fuel contamination or unexplained injector damage
- Any injector replacement or major fuel system service
- High-kilometre vehicles, typically 120,000 to 150,000 km
Over time the internal steel surface of a high-pressure line can degrade, and under rail pressure those particles end up in the injectors. Avoid bending or re-shaping lines during servicing, including rocker cover removal: a reshaped pipe is a pipe that cracks later.
Installation Notes
- Replace all four lines as a set when servicing injectors
- Torque fittings to factory specification
- Maintain strict cleanliness: contamination is what kills common rail injectors
- Prime the fuel system before cranking
