Is this the one you're talking about ??
Fuel Vapor Valve
The fuel vapor valve uses a small orifice and shutoff valve to allow only fuel vapor, not liquid, to pass into the vapor line routed forward to the fuel vapor canister. This fuel vapor valve mounts directly to the fuel tank, using a rubber grommet.
Fuel vapors in the sealed fuel tank are vented through the orifice in the top of the tank. The vapors are transmitted through a single vapor tube to the fuel vapor canister at the front of the vehicle. A spring loaded poppet valve provides pressure relief ahead of the orifice to fuel vapor canister. The poppet valve gradually opens above 5-6 kPa (20-24 inches H2O) to vent vapors to atmosphere through a second vapor tube.

There is also an Orifice tube in the A/C system. Not sure where it is on the Conti though.

Yes, sorry about that i am talking about the Orifice tube for the A/C system.

Is this the one....
A/C Evaporator Core Orifice
Information regarding the use of an A/C evaporator core orifice replacement kit (E5VY-19D695-A) below. (The A/C evaporator core orifice has an orifice diameter of 0.0575 inch and is color coded orange.)
A/C Evaporator Core Orifice
The fixed orifice tube provides the required restriction creating the dividing point between the high and low-pressure liquid refrigerant. It meters the flow of liquid refrigerant into the A/C evaporator core. A/C evaporator core temperature is controlled by a A/C cyclic switch (19E561) that senses the pressure within the evaporator core and A/C dehydrator and receiver tank. This A/C cyclic switch controls A/C compressor operation as necessary to maintain the A/C evaporator core pressure within specified limits.
The A/C evaporator core orifice is located in the liquid line near the A/C condenser core and has a filter screen located on the inlet of the tube body. The filter screen acts as a strainer for the liquid refrigerant following through the orifice opening. O-ring seals on the tube body prevent the high-pressure liquid refrigerant from bypassing the orifice. Adjustment or repairs cannot be made to the A/C evaporator core orifice assembly which cannot be removed from the liquid line. The liquid line must be replaced, or an Orifice Tube Replacement Kit (E5VY-19D695-A) installed if replacement of the A/C evaporator core orifice is necessary.
The A/C evaporator core orifice should be replaced whenever an A/C compressor is replaced. If the high pressure reading is higher than normal and the suction pressure drops rapidly creating a faster than normal A/C clutch cycle rate, the A/C evaporator core orifice may be restricted and should be replaced. This condition is usually indicated by the compressor having a short ON time and a long OFF time.
