Here is a picture of the gas tank before I re installed it not sure if it helps at all (I doubt it will help). You should be able to see the metal nipples that come off of the top of the tank I think there were 3 or 4. Unfortunately I do not have any other pics of the lines because before I installed the tank since I was not expecting there to be problems down the road. If needed I will drop the tank to get better pics.
Of course after loading the pics I see that the nipples are all on the other side of the bar laying on top of the tank.
