  Q: What precautions should be taken when servicing the fuel pressure regulator on Ford F-150 Heritage?

  A: Personal injury can occur because highly flammable mixtures require that motorists abstain from smoking and using open flames when servicing the fuel pressure regulator. Safety precautions require a technician to reduce fuel pressure first before they detach any fuel lines because the system maintains elevated pressure when the engine shuts off. Apply fuel pressure relief first before taking off the vacuum hose from the fuel pressure regulator system. Reduce the regulation through complete removal of the snap ring and fuel pressure regulator followed by waste of the aged O-rings. The new fuel pressure regulator installation requires specialized fuel-resistant O-rings instead of regular ones because ordinary O-rings produce leaks; also avoid using old O-rings. A simple approach to install new O-rings includes lubricating them with engine oil before placement followed by the backward order of steps needed to finish installing the fuel pressure regulator.
