What is one requirement for fuel line hoses, including metallic hoses?

Must exceed 60 inches in length
Must conduct electrical current without a jumper wire
Must be constructed of PVC material
Must have connectors made of plastic

The correct answer is: Must conduct electrical current without a jumper wire

One requirement for fuel line hoses, including metallic hoses, is that they must conduct electrical current without a jumper wire. This is essential for safety and functionality, as the ability to conduct electricity helps to prevent the buildup of static electricity, which can be a fire hazard. Sufficient grounding is crucial in fuel handling systems to ensure that any static charge is safely dissipated. While hoses could have specific design requirements based on their application, the materials and construction methods tend to be more regulated around safety aspects like electrical conductivity. Metal hoses inherently have conductive properties, but it is vital that all hoses within the fuel system adhere to this requirement to maintain overall safety. In contrast, other options such as the requirement for length, specific materials like PVC, or the use of plastic connectors do not align with the critical safety considerations needed for high-pressure fuel systems, where electrical conductivity is more pertinent.
