Abstract
A fuel cap fuel system and method establishing a common electric potential and preventing escape of fuel vapors as used with a fuel system. The cap includes a fuel port closure for engaging a fuel receiving assembly, and an electrically conductive retainer carried on the fuel cap. An electrical charge is passed from an operator of the fuel cap, through the cap, and to the electrically conductive retainer and to the fuel receiving assembly. As the cap is removed from the fuel receiving assembly, the conductive retainer maintains a conductive contact with the fuel receiving assembly to convey a charge therethrough. As fuel vapor escapes from the fuel receiving assembly, the electrical contact is maintained. The seal is disengaged from the fuel port after the cap and fuel receiving assembly achieve a generally common electrical potential.
