Can't fill tank after shortening
Shortened the gas tank (5.4L V8) in April, and have been converting my van to 4x4 ever since. Last month after finishing the conversion, I tried filling the tank and it would not fill easily, had to do it little by little.
I dropped the tank today to see if there was anything weird going on, but everything checked out AFAIK.
The only other answer is something to do with the EVAP system/charcoal canister, but I have NO codes coming up. Any clues on where to go from here? I don't want to spend $150-$250 on a canister just to find out it was not the problem...
