Make a smart choice for your diesel engines

Stop letting clogged injectors, pump failures, plugged filters, and other maintenance issues keep you from moving your business forward

Today’s diesel engine

A High Pressure Common Rail (HPCR) fuel system feeds individual solenoid valves to give-off fewer emissions, activate better fuel economy, and provide a quieter and more powerful drive.


  • More power
  • Reduced emissions
  • Improved injection metering
  • Higher injection pressure


  • Extreme high temperatures
  • Breakdown of ULSD fuel into basic carbon form
  • Fuel filter plugging
  • Internal Diesel Injector Deposits (IDID)
  • Injector nozzle tip coking

Save time and money on costly maintenance and repairs due to HPCR system drawbacks with Harness™ Premium Diesel Fuel
