Abstract
The present disclosure is directed to a fuel tank fill pipe assembly configured to conduct liquid fuel from a fuel-dispensing nozzle to a fuel tank. The fuel tank fill pipe assembly includes a filler head assembly shaped to receive the fuel-dispensing nozzle and a filler pipe that extends from the filler head assembly toward the fuel tank. In illustrated embodiments, a coupler is included for attaching the filler head assembly to the filler pipe while blocking fuel vapor from escaping the fuel tank fill pipe assembly so that hydrocarbons present in the fuel vapor are not released into the environment.
Claims10
A fuel tank fill pipe assembly adapted to conduct liquid fuel from a fuel-dispensing nozzle to a fuel tank, the assembly comprising
- a filler head assembly shaped to receive the fuel-dispensing nozzle,
- a filler pipe that defines a passageway for carrying liquid fuel from filler head assembly toward the fuel tank, and
- joint means for mechanically connecting the filler head assembly to the filler pipe and for sealing along an outside diameter of the filler pipe at the interface of the filler pipe with the filler head assembly to block fuel vapor from escaping the fuel tank fill pipe assembly so that hydrocarbons present in the fuel vapor are not released into the environment.
