Where is the compressed gas cylinder typically located in propane-fueled vehicles?

In propane-fueled vehicles, the compressed gas cylinder is typically located in the trunk. This placement is advantageous for several reasons. First, the trunk area provides ample space for storing the cylinder securely while protecting it from external elements and impacts during normal driving. Additionally, it allows for better weight distribution and minimizes the risk of gas leakage into the passenger compartment, which is a critical safety consideration.

Other locations, such as the engine compartment or under the rear seat, may not provide the same level of containment and safety. The roof location could also be impractical due to the need for easy access and potential exposure to damage from overhead obstacles. Hence, the trunk is the standard and safest choice for accommodating the propane cylinder.
