You fail to tell the a tubal
You fail to tell the a tubal design problem with the RAV4 tank. It is made like a saddle bag to fit around the AWD rearend. The pick up is at the bottom of one side. Once you pump out 4 gallons the saddle on one side can not flow to the pump pickup. This means only 9.5 gallons is obtainable from the design. Look up a replacement tank to see the design error.
