After inspecting the tank the clunk was touching the back of the fuel tank and when slightly tilted went into the very corner of the tank. It was so close it looked like it could possible starve the engine of fuel. Also it was hard to see through the tank but when I took the stopper out of the tank the supply fuel line was disconnected. So not sure if it came off while I was taking it apart, or if it already came apart. I ran out of time today but will shorten the intank line up and secure it better so it wont come off. I am sure this will fix it! Thanks for the great tips.
