What steps should I take to ensure my storage tanks are in good working condition?

While you are not required to take any steps to prepare your tanks for B5, the following preventive measures are recommended:
  • Prior to receiving B5, consume the existing product in the tank down as low as possible.
  • Before adding B5 to your system, check and remove water or sediment from the bottom of the tank.
  • Monitor your tank and product lines and conduct periodic testing to ensure the system is in good working order.
  • Replace any clogged fuel filters in the system from the tank to the dispenser.
