<p>Abstract DUAL FUEL SYSTEM FOR INTERNAL COMBUSTION ENGINE AND LEAKAGE LIMITING SEAL STRATEGY FOR SAME 5 A dual fuel system (20) includes liquid and gaseous fuel supplies (53, 23) and a fuel injector (25) in fluid communication therewith. A gaseous fuel check (71) in the fuel injector (25) forms a leak path (43) with a fuel injector body (39) between gaseous and liquid fuel passages (55, 49), and a leakage limiting seal (87) is positioned about the gaseous fuel check (71) and deformable 10 into sealing contact with the gaseous fuel check (71) responsive to an increase in a pressure drop from the liquid fuel passage (49) to the gaseous fuel passage (55) in the fuel injector (25).
