Isuzu Repair: 89 trooper, leak gas, horrible gas

Question
I have 89 trooper 5 speed 4 cyl put a new fuel pump in it but after runing it a while when you stop it will leak gas out of the can on the left of the moter looks like a vacume can. The shop I took it too messed with yhe vacume lines and return lines but cant fiqure it out any help is appreciated. thanks

Answer
Well Wade, this is called your vacuum purge control canister. If it's leaking that means your evap sensor is bad as well, do you get horrible gas mileage and poor idling as well as other problems, check your evap system and I bet you will find it is bad.
