What is the maximum allowable length of a fuel tank leg?

The maximum allowable length of a fuel tank leg being 12 inches is based on safety regulations that seek to minimize the risk of structural failure or instability of the tank. Fuel tanks are required to be adequately supported to prevent tipping or movement that could lead to spills or leaks, which are hazardous both environmentally and to public safety.

A leg length of 12 inches ensures that the tank is sufficiently elevated to allow for proper drainage and venting while also maintaining stability. This length conforms to industry standards and best practices, aligning with guidelines set by governing bodies that oversee fuel storage safety.

In reviewing the other length options, shorter legs would not provide adequate support for larger tanks, potentially leading to hazardous conditions. Conversely, excessively long legs could introduce instability, increasing the risk of damage to the tank or the components connected to it. Hence, 12 inches represents a balanced and safe choice for leg length to support a fuel tank effectively.
