Thanks. I am now going to beat the living s*** out of it. A few more dents won’t hurt.We tried to put the tank in when I first got the truck....it was on the lift and the tank was out.....it was a half hearted attempt. I think we determined that we wanted to lift the cab a little to get it in. We used a dead blow mallet to "adjust" the tank's flange a little. I am hoping to be messing with the front tank this week....once we get the rear one mounted. Working on that now.
