The fuel rail has a valve on it, but I don't know too many people that bother with it. Most that I know including myself just go after the filter. You'll get wet to a certain extent no matter what.

No air release. there is a high presure and a low pressure valve, these are used for filling refrigerant, checking pressures, and evacuating the system.

Pontiac 1993 vehicles have been known to have Fuel Pressure Regulators that when they fail, they will release too much fuel to the intake and therefore produce erratic or Idle up and down. Also, the erratic Idle can be caused by a air pressure leak located as part of the Emissions system.
Release the Pressure was created in 1992.
The fuel pressure regulator controls fuel pressure at the fuel injectors. It uses vacuum pressure to control the pressure. It is positioned on the end of the fuel rail. If they leak, fuel will go into vacuum line causing hesitation on start-up and the smell of gas at exhaust. Warning, Fuel is under pressure. Disconnect battery and release pressure before replacement.
