What to check

  • Tank size and the 80% fill limit
  • Lowest design temperature for the site

Fuel figures are estimator-grade. A manufacturer fuel curve at your load and ambient beats any generic curve; verify the nameplate rating, the actual load fraction, and the delivered fuel price before you size a tank or promise a runtime.
