Laser 8021 Fuel & Additive Funnel – Diesel Fillers (Grey/Silver) | Emergency Refuel & Additives

Meet the Laser 8021 Fuel & Additive Funnel, a purpose-built tool for diesel vehicles designed to simplify refueling and additive dosing when you encounter anti-misfueling flaps. This compact funnel is crafted to work with restricted filler openings, turning a tricky task into a smoother, more controlled pour. While outcomes vary by setup, users may experience quicker top-ups, reduced spills, and easier additive dosing with a dedicated diesel funnel at hand.

Designed specifically for diesel fuel fillers

Engineered to fit diesel filler necks and compatible with anti-misfueling flap systems, the 8021 helps you access the filler from within the flap by guiding fuel or additives with purpose-built precision. It’s ideal for emergency refueling from a can or for pouring in additives like cataclean, all without wrestling with the opening or risking splashes.

• Outlet diameter: 24.5mm. For diesel fuel fillers only.
• For emergency fueling or adding fuel additive (such as cataclean).
• Manufactured from polypropylene.
• Fuel & Additive Funnel available for petrol - please see Laser Part No. 8020.
• Included components: Fuel & Additive Funnel - Diesel

Real-life use cases and benefits

Imagine a roadside hover with a diesel can or a service stop after a long drive. The 8021 provides a controlled path for liquids, reducing spill risk and helping you complete a top-up even when space is tight. The durable yet lightweight polypropylene body offers a reassuring grip and a straightforward flow path, making routine maintenance tasks more convenient even in less-than-ideal conditions.

Using the funnel to introduce additives into the diesel stream expands your maintenance options without needing additional tools. The diesel-specific design helps keep the fill line clean and predictable, supporting tidy refuels in everyday scenarios and on longer journeys alike.

What you get and material details

This product ships as a focused Diesel Fuel & Additive Funnel, with a simple, purpose-built build meant to endure regular use. For fleets that operate across fuel types, Laser also offers a petrol version (Part No. 8020) to cover broader needs, making it easier to standardize refueling routines across vehicles.

Care, longevity, and user considerations

Rinse after use and allow to dry before storage to extend life. The polypropylene construction provides durability while remaining lightweight and easy to handle. While the funnel is designed for diesel usage, always verify compatibility with your vehicle’s filler system and anti-misfueling flap configuration before use. This is a practical accessory rather than a guaranteed fix, offering a controlled solution where applicable.
