Frequently Asked Questions
Q: What is a generator day tank?
A: A day tank is a smaller fuel tank installed near the generator that automatically maintains a ready fuel supply. A transfer system moves fuel from a larger bulk tank to the day tank as needed.
Q: How long can diesel fuel be stored in a generator tank?
A: Standard diesel can degrade within 6-12 months. Fuel treatment products extend storage life. For standby generators that may sit unused for months, a fuel maintenance program is essential.
Q: What size generator fuel tank do I need?
A: Calculate your generator's fuel consumption rate multiplied by the hours of runtime you need. Most facilities want 24-72 hours of continuous operation.
