Fuel line heater feedthrough.

摘要

A fuel feedthrough and heating assembly comprises a fuel conduit and a neck portion through which a self-regulating PTC heater is introduced into the fuel conduit. A seal prevents fuel from exiting through the neck portion, and the connections between the electrical leads to the heater and the conductors of the heater are encapsulated within the neck portion by a fuel-resistant insulating composition. The assembly is particularly useful for heating diesel fuel, e.g. in vehicles and locomotives.
