Claim:
1. A sealing system, comprising: a cylinder head; a coupler positioned in the cylinder head; a fuel injection line extending into the coupler so as to at least partially define a fuel leak passageway therebetween; and a cap, wherein the fuel injection line extends through the cap, the cap yieldably urges itself into a seated position in which the cap establishes a first sealed connection with the fuel injection line and establishes a second sealed connection with the coupler, so as to block ingress of moisture into the fuel leak passageway, the cap is adapted to move from the seated position to an unseated position in response to a pressurized leaked fuel, in the fuel leak passageway, so as to allow the pressurized leaked fuel to flow out of the fuel leak passageway, and the movement of the cap away from the seated position to the unseated position is caused by the first sealed connection between the cap and the fuel infection line being broken.
