My experience has been the sender.. filled with fuel and wouldn’t float.

My 05 Excursion did this when I bought it last year. I read that there is build up on the sender card. I read to run Chevron with Techron concentrate in the fuel. I ran the big black bottle from Walmart. It took about 6-7 tanks of fuel, but it finally quit doing it and has worked normally ever since.
