A component of a fuel combustion system of an engine includes a body and a thermal conductor member. The body includes a fuel surface configured to be in heat-transferring relationship with a fuel source within the fuel combustion system. The body is made from a first material having a first thermal conductivity value. The thermal conductor member is disposed within the body and is made from a second material, which is different from the first material and has a second thermal conductivity value that is higher than the first thermal conductivity value. The thermal conductor member includes a first end disposed adjacent the fuel surface and a second end in distal relationship thereto. The thermal conductor member extends between the first and second ends along a thermal conduction path defined within the body and extending away from the fuel surface.
