Having problems with your Chevrolet S 10 ?

I have a 2003 S-10 crew cab with the V-6 vortec engine my service engine light came on showing a po442 fuel system vacuum leak and then when i went to fuel up fuel is backing up so i unhooked vent hose from charcoal canister and its ok to fuel so i know something down there is plugged or not working but don't want to replace everything

Answers :

This is either going to be the charcoal canister being full or plugged, or the hose being colapsed or plugged. Try a new hose first, then the canister.
