A:
"there is no relay the problem you have sound like the float is sticking on the slider rod inside your gas tank you can get a good fuel system cleaner to run in it and it should fix your problem the best fuel sytem cleaner i have found is called "LUCAS" you can buy it at autozone for about five bucks."
