I've been through 2 summers with the car, and the only trouble I have had before is if I run the pump on high, and it might stop filling up 1-2 gallons short. Now though, I can run any pump I use on the lowest setting, and I am having to click-click-click from 5-8 gallons up to the full 14 or so. I don't know why the difference this spring.........I mean you can say heat and expansion all you want, but it never was like this last summer.......
