I wanted to ask what yall recommend, I have a 2004 Silverado 1500 ext cab, its bagged and it has a plastic fuel cell in the back where the spare tire used to be. My only problem is the check engine light is on, I just need to do something to get it to turn off, when they installed the fuel cell, all the other stuff got thrown out the evap canister I think that's what it was called (black plastic box) im wondering if to go back to the stock gas tank and raise it or just get a aluminum fuel cell and put the evap canister and see if it works. Any body has ran in to that problem
