Get the water out of a small amount of fuel for under $25
Mr. Funnel AF8CB Fuel Filter is the answer.

For water contamination is small amounts of fuel.

Pour it through the funnel and it separates the water. Fuel is cleaned as the water stays behind.

Frequently Asked Questions About Fuel Funnel Water Removers

What is a fuel funnel water remover?

A fuel funnel water remover is a special funnel designed to separate water and debris from fuel while you pour it into a tank. Unlike a standard funnel, it uses a filter screen and water-repelling media to allow fuel to pass while trapping water and contaminants.

How does the Mr Funnel AF8CB work?

The Mr Funnel AF8CB allows diesel or gasoline to pass through while retaining free water and debris in the funnel. Water remains behind and clean fuel flows into the equipment tank.

Can a fuel filter funnel remove water from diesel fuel?

Yes. The funnel is designed to separate free water from diesel fuel during pouring operations. It is an excellent solution when transferring small quantities of fuel that may contain water contamination.

What types of fuel can be used with a Mr Funnel?

Most models can be used with:

  • Diesel fuel
  • Gasoline
  • Kerosene
  • Heating oil
  • Biodiesel blends

Always verify compatibility with the specific funnel model.

How much contaminated fuel can a funnel handle?

Fuel filter funnels work best for smaller volumes of fuel. If you are treating fuel cans, equipment tanks, portable generators, boats, ATVs, or service equipment, they are highly effective. For bulk tanks or large storage systems, fuel polishing is generally a better solution.

Can a fuel funnel remove sludge?

The funnel can remove larger particles, dirt, rust flakes, and debris. However, severe sludge contamination usually requires fuel polishing, filtration, or tank cleaning.

Will the funnel remove microbial contamination?

Not directly. A funnel can capture some microbial debris and sludge, but it does not eliminate active microbial colonies. Water removal and fuel polishing are often required for serious contamination problems.

Is a fuel filter funnel useful for emergency generators?

Yes. Many generator owners use filter funnels when transferring fuel from containers into standby generators. This provides an extra layer of protection against contaminated fuel entering the tank.

Can I use a fuel funnel for marine applications?

Absolutely. Fuel filter funnels are commonly used by boat owners because marina fuel, portable containers, and dockside fueling operations can introduce water contamination.

What are signs that fuel contains water?

Common indicators include:

  • Cloudy fuel
  • Water droplets in samples
  • Corrosion in tanks
  • Plugged filters
  • Hard starting engines
  • Rough engine operation

If water is suspected, remove it before operating the equipment.

Is a funnel water remover a replacement for fuel polishing?

No. A funnel is designed for fuel transfer and small quantities of fuel. Fuel polishing systems are designed to continuously remove water, sludge, sediment, and contamination from larger storage tanks.

What size fuel problems is a funnel best suited for?

A funnel is ideal for:

  • Fuel cans
  • Portable generators
  • Boats
  • ATVs and UTVs
  • Construction equipment
  • Farm equipment
  • Pickup trucks

For tanks larger than approximately 50 gallons, additional filtration or polishing may be more appropriate.

Can a fuel filter funnel save expensive repairs?

Yes. Preventing water and debris from entering injectors, pumps, carburetors, and fuel systems can reduce maintenance costs and improve equipment reliability.

What should I do if I discover large amounts of water?

If significant water contamination is present:

  1. Stop using the fuel.
  2. Test the fuel condition.
  3. Remove free water.
  4. Filter or polish the fuel.
  5. Clean the tank if necessary.

A funnel works best for prevention and small contamination events rather than major tank cleanup.

What is the easiest way to prevent water contamination?

  • Keep fuel containers sealed.
  • Store tanks as full as practical.
  • Test stored fuel periodically.
  • Remove water immediately when detected.
  • Use a fuel filter funnel during transfers.

These simple steps help reduce fuel-related failures and downtime.

Need Help With Water in Your Fuel?

For small fuel transfers, a fuel filter funnel is often the quickest solution. For larger tanks, generators, marine systems, and bulk fuel storage, Dieselcraft offers fuel testing, water removal, and fuel polishing solutions.
