Here's what's generally involved, but I strongly advise against attempting this yourself unless you're very comfortable working with fuel systems:
* Safety First: Work in a well-ventilated area, far from any ignition sources (cigarettes, sparks, etc.). Wear safety glasses and gloves. Have a fire extinguisher nearby. Consider working outdoors.
* Locate the Fuel Tank: The fuel tank is typically located under the vehicle near the rear axle. You'll need to get underneath the van.
* Access: You'll likely need to remove some underbody panels or shields to gain access to the fuel tank and fuel lines. Consult a repair manual for your specific model year to identify the location and access points.
* Fuel Pump Removal (Most Common Method): This is the most reliable way to drain the tank, but it's more involved. It usually requires:
* Disconnecting the Battery: This is crucial to prevent electrical shorts.
* Dropping the Fuel Tank (or at least partially): This often requires disconnecting fuel lines, electrical connections, and possibly support straps. This is difficult and you need to properly support the tank to prevent damage.
* Removing the Fuel Pump Assembly: This exposes the fuel level inside the tank allowing the fuel to be siphoned or pumped out. Be careful not to damage the fuel pump or other components during removal.
* Siphoning or Pumping the Fuel: Once the pump assembly is out, you can use a siphon pump or a specialized fuel transfer pump to extract the remaining fuel.
* Other (Less Reliable) Methods: There might be some access to the tank through openings near the filler neck, but this is usually very limited and may not drain the entire tank. These methods are generally not recommended.
Critical Considerations:
* Repair Manual: Obtain a repair manual specific to your 2004 Dodge Sprinter 2500. This will provide detailed diagrams and instructions for accessing the fuel tank and fuel pump.
* Professional Help: This is a complex task that involves working with flammable liquids and potentially delicate components. If you're not comfortable performing this task yourself, take it to a qualified mechanic. They have the proper tools, knowledge, and safety equipment.
* Disposal of Fuel: Properly dispose of the drained fuel according to local regulations. Don't simply pour it on the ground.
In short, draining the fuel tank on a Sprinter is not a job for the average DIYer. The risk of injury and damage far outweighs any potential benefit of attempting this yourself. Professional assistance is strongly recommended.
