How to Service the Fuel Pressure Sensor on Mercury Mountaineer?

Disconnect battery ground cable to avoid sparks to service the fuel tank pressure sensor. Take out the EVAP canister and fuel tank shield, sever the sensor and fuel pump couplings. To install the new sensor, repeat the steps in a reverse way, after which a leak test and a verification drive cycle should be carried out.

What Safety Precautions Should Be Followed When Servicing the Fuel Pressure Sensor on Mercury Mountaineer?

When servicing the fuel pressure and temperature sensor, then be safe considering flammable mixtures. Disassemble the intake manifold and the parts one after another, releasing the fuel system pressure, then disassemble the parts sequentially. Install new fuel-resistant O-ring seals which are lubricated with clean engine oil to avoid leakage. Install again by undoing the process of uninstalling.
