Taurus V6-232 3.8L (1989)
temperature increases, overfilling ("topping off") can cause fuel overflow at the filler cap when the vehicle is standing or the cap is removed.
FUEL SUPPLY MANIFOLD
Fuel Supply Manifold
The fuel supply manifold delivers high-pressure fuel from the vehicle fuel supply line to the fuel injectors. The assembly consists of a tubular fuel rail,
six injector connectors, a mounting flange for the fuel pressure regulator and mounting attachments which locate the fuel manifold assembly and provide
fuel injector retention. The fuel inlet and outlet connections have push connect fittings.
SEALED FILL CAP
The sealed cap incorporates a build-in pressure-vacuum relief valve. Fuel system vacuum relief is provided after approximately 0.50 inches vacuum is
reached inside the tank. Pressure relief is provided when pressure inside the tank builds up approximately 2.2 psi. Under normal operating conditions, the
fill cap operates as a check valve preventing vapors from escaping the tank through the cap.
VAPOR VENT
Vapor Vent
In-tank venting provides a vapor space above the gasoline surface in the fuel tank. This area is sufficient to permit adequate breathing space for the tank
vapor valve assembly under all static and most dynamic condition.
