While many DIYers can replace a section of fuel line, the 2005 Caravan’s routing through the unibody frame is tight. Consider professional help if:
– The main feed line runs inside the unibody frame rail, protected by plastic retainers. At the rear floor pan, it crosses slightly toward the center.
The fuel line emerges near the firewall and connects to the fuel rail using a quick-disconnect fitting (often blue for identification).
[Fuel Tank] → (Fuel Pump Outlet) → [Quick-Connect] → (Nylon Feed Line along inside of driver side frame rail) → [Fuel Filter (integrated into line on some models)] → [Engine Compartment] → [Fuel Rail (rear of engine)]
As the lines reach the engine bay, they route upward near the firewall.
Long crank time, especially after sitting overnight.
The main supply line is bundled with vapor lines and runs along the driver-side frame rail.

Using the routing knowledge above, here are the top three locations where 2005 Caravans develop fuel line issues:
