Where is the vent control solenoid located in my 1999 4.0 Cherokee and is the evap. solenoid a separate part or are they the same thing. I know about the one in the engine compartment next to the evap pump. Im looking for the one that when held closed prevents the fuel tank from filling at a regular rate. Articles that I read make it sound like two separate components. - Ii pulled both vacuum hoses off of the solenoid in the engine compartment. i went to get gas, Pump still kept cutting off. Must be another solenoid somewhere, thought i traced all three hose coming out of charcoal canister - Thanks
