After the car has run and is shut off, and even when the key is in the start position, there is a bump sound coming from the fuel tank. It is kinds repitious sorta a *bump* bump bump* bump* bump bump. Is my pump going bad or is it just "bumping" against the side of the tank? The pump is a walbro 255 High Volume Pump. Please help!
