Diesel Tank Funnel – Easy filling for diesel vehicles with a non-return flap

Do you find it difficult to add a diesel fuel additive without spilling? Many modern diesel vehicles have a non-return flap or misfuelling protection inside the filler neck, making it harder to pour additives or emergency fuel directly into the tank.

The Z-8021 Diesel Tank Funnel makes filling easier, cleaner, and more controlled. Its long neck opens the internal flap in the diesel filler opening, allowing diesel additives or fuel to flow directly into the tank without unnecessary mess.

What problems is this suitable for?

The Diesel Tank Funnel is commonly used for:

  • Adding diesel fuel additives without spilling
  • Opening the non-return flap in diesel filler necks
  • Emergency refuelling with diesel fuel
  • Hard-to-reach or narrow diesel filler openings
  • Cleaner and more controlled filling during maintenance

When the fuel filler opening makes it difficult to pour directly from a bottle, a dedicated diesel funnel makes the job easier and helps prevent waste.

How does it work?

Insert the funnel into the diesel filler opening until the long neck opens the internal flap. Once positioned correctly, diesel additive or fuel can be poured through the funnel directly into the tank.

The angled, notched anti-splash edge helps make filling easier and reduces the risk of spilling product around the filler opening.

Suitable for diesel vehicles

The Z-8021 Diesel Tank Funnel is suitable for diesel vehicles with or without a non-return flap. It is especially useful for cars and vans equipped with misfuelling protection in the filler neck.

The funnel is made from strong polypropylene plastic and is designed for diesel use only. For petrol vehicles, use the dedicated petrol version instead.

Practical accessory for clean filling

Adding diesel additives should be quick and clean, without struggling with the filler opening or spilling product on the vehicle. A dedicated diesel funnel guides the liquid directly into the tank and makes regular fuel system maintenance easier.

The Z-8021 Diesel Tank Funnel is ideal for anyone who regularly uses diesel additives or needs a simple tool for vehicles with a diesel tank non-return flap.
