89 Regal Valanti 225 SC - 5.7 Mercuiser / <br />The gas tank tucks nicely beneath the floor and has two 1/16"x2"x2" aluminum "L" channel braces spot welded along the top edge of the tank. The channel is used to fasten the tank to the boat framing. Problem is...several spot welds have broken. I figured that I'd remove the tank and have the channel re-welded and then re-install. I emptied the tank and when I tried to remove it the tank will not BUDGE! Do you think the factory used some sort of glue underneath? There is a gap all the way around it so it's not wedged in. It looks like maybe foam strips coming up the sides for a cushion. I'm sure that I'll have to remove the tank and fill with water to have it welded...right? Do I really need the channel? Please help! THANKS!
