“2 issues- the distance to empty only reads 425 miles. With a full 17 gallon tank it should be around 600. When you fill it, it clicks off 3-4 gallons short of full, only holding about 14 gallons. The fuel gauge shows full. I then had to trickle in the remaining 3.5 gallons. How could it show full with 3.5 more gallons going in? Why is the tank not able to take the full ammount of fuel?”
