Does your gas tank make noise? my tank is behind the seat and with a 1/2 to full tank of gas when I turn a corner the fuel moves from side to side (as it should) but as it does the tank flexes and makes a loud sound it's hard to describe the sound but if you have ever held a thin piece of sheet metal between both hands and shook it in and out...that's the sound. Scares the crap out of my passengers they think the beds falling off or something. Maybe i've got a thinner metal after market replacement tank?.

I hear a lot of clanging at 1/2 tank... that's the float smacking the front and rear wall of the tank. But I have never heard the sheet metal flexing. You may well have an aftermarket thin wall tank.

Dam!! I thought it couldn't be normal and now you've confirmed it. I think i'll have metal pads or something welded to the surface to strengthen it, there's not much else I can do.

Thanks guys.

I still have the original tank and mine does the same thing. Only seems to do it on our gravel road going around corners.Loud thump.. Mines the non eec if that makes any difference.
