How to Service and Repair the Fuel Pressure Sensor on Mercury Grand Marquis?

The servicing process for the fuel tank pressure sensor should begin with disconnecting the battery ground cable as this helps prevent electrical spark ignition of fuel vapors. The service technician needs to disconnect the fuel tank pressure sensor electrical connector during tank lowering while partially draining tank fuel to avoid harming equipment. The sensor requires removal through a counterclockwise rotation motion after pushing it down. You should follow the removal procedure in reverse to install the part. Also perform a leak test of the complete system and verify proper functionality. Complete the verification process by driving the vehicle as needed to evaluate complete system operation.
