Before the TSB was issued I carried a piece of 3/16" nylon tubing 55" long. When it would act up I'd slide that the fill until it met with resistance. Then I'd jab it back & forth and loosen the Flapper. One day I didn't have it in the trunk, however I had an antenna element Stainless steel well in my rage I do believe I broke the flapper off. Been 2 years NO problems!!!!!
Beside the little flapper the size of a quarter, well it looks like a prize in a box of Cracker Jacks.
