Before doing anything, determine how the gasoline got there. Was there a misfueling? Is there some other unusual circumstance?
If you're certain there's gasoline in the diesel tank:
1. Don't start the engine: Running the engine with gasoline in a diesel system will cause severe and likely irreparable damage.
2. Locate the fuel tank access: This is usually under the vehicle, often near the rear axle. You might need to raise the van securely on jack stands for safe access. Safety first! Use jack stands, not just a jack.
3. Drain the tank: This is the most straightforward method. You'll need a siphon hose (available at auto parts stores), or a pump designed for transferring liquids. The siphon method might be slow. A manual pump or electric transfer pump will be quicker and more efficient. Be extremely careful not to spill any fuel. Gasoline is flammable and poses a significant fire hazard.
4. Dispose of the gasoline properly: Gasoline is hazardous waste and cannot be simply poured down a drain or onto the ground. Contact your local waste disposal authority or a recycling center to find out the proper disposal method in your area. Many gas stations will accept small quantities of gasoline for disposal.
However, it's crucial to reiterate: Double and triple check that there is actually gasoline in the diesel fuel tank. It's much more likely there's a misunderstanding about the fuel type or the vehicle itself. If unsure, consult a qualified mechanic. They can safely assess the situation and advise on the best course of action. Improperly handling fuel can lead to serious injury or death.
