The lincoln better idea engineers put the low side freon port in a peculiar place.. You will find the low pressure port near the compressor under the car on the driver's side. You will need to put your car on a lift to get to it. Once you raise your vehicle, take the plastic shields off and you will find the compressor...yup...it's a tight spot.

To relive the fuel pressure look under hood on drivers side front of engine locate the fuel line where it goes into the fuel rail,trace it back a little ways and you will see a schrader valve for checking fuel pressure. Remove the plastic cap and take something like a small screw driver and press the pin in center to release pressure.
To replace fuel filter you have to remove left front wheel and inner plastic fender panel and fuel filter is located behind this at the back area.
