To know for sure, you need to:
* Check your specific vehicle's parts diagram: Use your VIN number on a Ford parts website (like FordParts.com or a similar reputable dealer site) to access a parts diagram specific to your truck. This is the most reliable way to determine the hose configuration.
* Visually inspect your hose: The simplest method, but only if you can easily access the hose. If it's a single, continuous hose, that's your answer. If it has a visible connection point, it's likely a two-piece design.
Don't rely on general information found online, as it's prone to inaccuracies and variations. Always check your truck's specific parts diagram for definitive information.
