What should the weight of fuel supply cylinders not be supported by?

Brackets and nuts
Manifolds and valves
Cylinder frames
Rubber insulators

The correct answer is: Manifolds and valves

The weight of fuel supply cylinders should not be supported by manifolds and valves because these components are not designed to bear the structural load of the cylinders. Manifolds and valves are critical electrical and mechanical components that manage the gas distribution and flow, but they don't provide the necessary structural integrity or support to hold the weight of the cylinders themselves. If the weight were placed on these parts, it could lead to mechanical failure, gas leaks, or hazards associated with improperly secured gas equipment. Proper support structures, such as brackets, nuts, and cylinder frames, are engineered to handle the weight and ensure stability while keeping safety as a priority. Rubber insulators, while they can help reduce vibrations, are also not appropriate for supporting the weight of the cylinders directly. Instead, they are used to dampen movement and protect against vibration damage.
