How to Determine the Difference Between California and Federal Fuel Tank Models
Under the front passenger wheel, you can see the fuel pipe that leads to the tank. On California models (Pictured), you can see a decrease in the tube size (from a circumference of 7.5" down to 5") right after the filler opening. In contrast, in federal models, the tube stays at a constant circumference of 7.5" from the filler opening to the tank. If the filler neck tapers down, you need the 57.5/50mm grommet. If it stays the same circumference, you need the 70/57.5mm grommet.
