What precautions should be taken when servicing the fuel pressure regulator on Mercury Grand Marquis?

When servicing the fuel pressure regulator, avoid smoking or open flames near fuel components due to flammability. Relieve fuel pressure before disconnecting lines. Remove the upper intake manifold, disconnect the vacuum hose, and take out the regulator. Use new fuel-resistant O-rings for installation and lubricate injector pockets with clean engine oil.

How to service and repair the fuel pressure regulator safely on Mercury Cougar?

To maintain the fuel pressure regulator, be careful not to be near flames around fuel parts. Venture fuel pressure, detach hoses and take off the regulator. To install, do the reverse steps with a lubrication of the new O-ring with clean engine oil of the Ford specification. Care should always be taken with fuel components.
