High Pressure Common Rails

HP Rails, or High Pressure Common Rails, refers to the rail feeding fuel into the injectors in any line of cylinders at extremely high pressures.

As the fuel is located close to both the injectors and the HP Rail, fuel is delivered to the combustion chamber very quickly. So your diesel vehicle is optimised for efficiency, refinement, and performance.

Baileys Blueprinted rails have been built in Australia at the Baileys Diesel Technology Centre, to the highest standards. Every rail is thoroughly cleaned (both chemically and physically), then a 100% sensor and dump valve replacement occurs - making these units every bit as good as a new unit. At a fraction the usual cost.

  • High engine power
  • Smooth and quiet running
  • Low fuel consumption
  • Low emissions
  • Clean and efficient fuel injection

Note: Having correct filtration is the main and first line of protection to avoid damage to common rail system components. A filter kit goes hand in hand with quality HP rails to reduce fuel and contamination problems (and to protect your big dollar components: injectors and fuel pump).

Hey Tim. The work you did on my 79 series is great. The increase in power and torque is fantastic. Seamless and smooth delivery across a nice wide band from 1,000 RPM in fifth with no holes or flat spots. You've made a new car heaps better to drive. Thanks. - Peter Rowley
