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
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.
