1988 Charcoal Canister Hose Connection

Recommended Posts

On my 1988 5.8L the charcoal canister in the front has a hose going to the gas tank, and a second hose that goes where? Mine is just dangling free...

I seem to be missing the purge solenoid valve, but I don't know which of the many purge valves I need to replace it. The hose has a "V" connector with two more hoses. Is that even correct? Anyone have the 1988 5.8L ? Can you describe where the canistor hose goes and what part it connects to? My manual indicates the EFI engine has some sort of electrical connector solenoid. Post some pictures?

Looks like the other is to an Engine Manifold Vacuum port, or Tee/at intake manifold or throttle body

V REST on later years is Vapor Valve (Roll-Over); Depictions & Location Diagrams in 5.0, 5.8, 7.5, & 4.9; "...All fuel tank vapor valves make use of a small orifice that tends to allow only vapor and not fuel to pass into the line running forward to the vapor storage canister. This assembly mounts directly to the fuel tank using a rubber seal. Fuel vapors trapped in the sealed fuel tank are vented through the orificed vapor valve assembly in the top of the tank. The vapors leave the valve assembly through a single vapor line and continue to the carbon canister for storage, until they are purged to the engine. The vapor valve assembly mounted on the top of the fuel tank is used to control the flow of fuel vapor entering the fuel tank vapor delivery line which conducts vapor forward to the canister in normal circumstances. If due to extreme conditions, excessive pressure is generated inside the tank, the purge port opens up, allowing fuel vapor to escape to the atmosphere, and stabilizes pressure inside the tank. The valve assembly has a head valve which prevents the fuel tank from overfilling during refueling operation. The valve assembly also has a spring supported float assembly, which prevents liquid fuel from entering the vapor delivery line during severe handling, steep grades or in the event of vehicle rollover. The fuel fill cap is sealed and includes a built-in pressure-vacuum relief valve. Fuel system vacuum relief is provided after 3.5 kPa (0.50 psi) and pressure relief after 11.0 kPa (1.6 psi). Under normal operating conditions, the fill cap operates as a check valve, allowing air to enter the tank as fuel is used, while preventing vapors from escaping the tank through the cap..." by Ford via Steve83 at http://www.supermoto...ry/media/283481

Vapor Valve (V REST) pics in 5.0, 5.8, & 4.9...The smaller valve uses a thicker grommet to fit in the same hole as the larger one..." by Ford via Steve at http://www.supermoto...ry/media/767956'>http://www.supermoto...ry/media/767956


V REST on earlier years such as SEABRONC's 83 is a Vacuum Restictor/delay valve, it delays vacuum for a certain amount of time. See his Vacuum Line Diagram (modified to reflect changes He made) at http://www.supermoto...ry/media/767956


MAN VAC is Manifold Vacuum


CAT is the catalytic converter


ENG is the engine


PCV is Positive Crankcase Ventilation Valve
