A rail pressure sensor reading past its range is a limp-mode waiting to happen. The Exergy 01-04 Duramax LB7 Rail Pressure Sensor (store SKU xrgE05 10121) reads across the pressure a modified fuel system actually runs.

  • A direct electrical and thread replacement, so it reads correctly without an adapter or a harness change.
  • Pairs with a raised-pressure fuel system where the factory sensor would be running at the top of its scale.
  • Application-specific to the Duramax LB7 fuel system rather than a universal part, so check the Fits line below against your own truck before ordering.

Fits: 2001-2004 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD with the 6.6L Duramax LB7. The 2004 split is mid-year: later-2004 trucks are LLY and take an LLY part instead.

Perfect for a modified fuel system that needs a sensor reading the pressure it actually runs.
