  • Pressure relief system for diesel exhaust fluid storage
    Patent number: 10215069
    Abstract: A system for diesel exhaust fluid (DEF) vessel pressure relief for a vehicle is includes a diesel exhaust fluid (DEF) storage tank, and a DEF pump assembly in an interior of the DEF storage tank. The DEF pump assembly includes a DEF pump having a pump body, a fluid pressure sensor fastened to an exterior of the pump body and configured to sense a DEF pressure, and a fluid temperature sensor fastened to the exterior of the pump body and configured to sense a DEF temperature. The system further includes a fluid channel, and a heating element in thermal communication with the fluid channel, where the heating element is configured to heat the fluid channel to displace DEF from a location proximate to the pump body.
