It’s called an ultramar now
Owner was abusive and called me derogatory names when there was a break in a transfer pipe between my two fuel tanks. Told my I was stupid because I wouldnt start the car to move it with the exhaust covered in gasoline. It is a common problem in the vehicle I was driving but there is never any warning when it happens. The failure is in a physical connection and there is no way to foresee it. Im a licensed mechanic of 42 years and the car is serviced by me in my shop twice as often as is recommended by the manufacturer.
