<p>A heated coupling (20) for a fuel delivery system is provided particularly adapted for use with diesel engine (26) powered vehicles. When the fuel systems are exposed to low ambient temperatures fuel clouding and waxing can occur, which restricts fuel flow to the associated engine. Fuel clogging problems are particularly acute at the fuel tank outlet and in the coupling at the fuel outlet. In accordance with this invention, a heating means such as an electrical heater (28) is provided for increasing the temperature of those fuel clogging areas to reduce wax accumulation. In accordance with an alternate embodiment, a passive heating element (44) is used which is in thermal engagement with an active heating element to conduct heat into the fuel reservoir.</p> |
