Mr. Funnel?

(

Go buy a Mr Funnel, then buy some diesel from your local filling station. I will wager that you will get close to 1 cup of liquid that does not make it thru the Mr Funnel per 5 gallons.

You can read the Mr Funnel propaganda here:
Mr Funnel web site and
Here )

This is exactly what I am talking about. In my case this 1 cup remaining at the bottom of the F8NC (Large) Mr. Funnel was clean, uncontaminated diesel fuel . If you look at the filter, there is a plastic ring on the lower edge of the filter that will not allow the last 1/8" or more of fuel that remains at the bottom of the funnel to pass through. You can not shake the funnel to get it through because there is not enough "head pressure" to force the liquid through.

You may be throwing good fuel on the ground. Granted, 1-2 cups of fuel on the ground is not a lot, but it IS a waste and if thousands of people using Mr. Funnels are all doing it, it adds up. /forums/images/graemlins/mad.gif

( was clean, uncontaminated diesel fuel )

Are you sure? Just because it looks like diesel does not mean it is pure uncontaminated diesel. How do you even know if its uncontaminated? You cannot tell by looking, even with dyed diesel.

ALL pump diesel, off-road diesel, kerosene, and home heating oil contains water. That is a fact. Mr Funnel does a much better job of straining the water than your fuel system's filter or water seperator. All diesel systems are designed to tolerate some amount of water in the fuel. The manufacturers documentaion will tell you how much. Less is always better.

I would throw away or dispose of appropriately any liquid that remains in the Mr Funnel because it contains a very high percentage of water. One cup of liquid in 5 gallons is not unusual.

If you are not satisfied with you Mr Funnel you can always return it for a full refund, within 30 days of purchase.

Just spoke with their customer service. They said that the F8NC funnell will hold 5/8 of a cup. He said that if there is water trapped in the funnel with the diesel fuel, that you would see it. He recommended looking at the fuel and if it was not contaminated to put it into the tank.

I elected to go with the F3NC funnel which only holds 3/8 of a cup.

I dump mine in an empty w/washer jug. I may try when it is full to see how much will pour into another jug and if it is usable. G

( When I buy diesel now from the service station pump, my Mr Funnel traps anywhere from 1-2 cups of liquid per 5 gal can.)

Whoa!!! /forums/images/graemlins/shocked.gif /forums/images/graemlins/shocked.gif

I know this is going to sound cheap and petty, but at $1.60 per gallon diesel fuel, you are talking 20 cents worth of useless water in every 5 gallons of fuel! Or another way....2.5% of your purchase was water, and not the product you purchased. A hidden 2.5% price increase seems like a bad deal for the consumer. Don't bars and restaurants get into serious trouble for watering their booze? Seems like the same thing to me.

( However, Mr Funnel, according to their propaganda on the web site, will trap any molecule up to .005 inches in diameter.)

.005 Inches??? That has got to be the biggest darn molecule in the entire universe!! /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

It's not. The service stations are not deliberately watering down their diesel fuel.

GerardC · Jul 19, 2004

I've thought the same thing. In time, it adds up to many $$'s of wasted money.
Also, you make a very good point about watered down. There should be a law, then again, we're talking about the government here. /forums/images/graemlins/smirk.gif G

That's their quote, not mine.

Diesel fuel, by the nature of its molecular structure, will absorb moisture that is present. That is why all diesel (hydrocarbon fuels) will contain some amounts of water. I am not a chemist and don't claim to be an expert but here is a propaganda blurb from the Mr Funnel website that sheds light on the subject.

( When properly used, the filter will separate FREE WATER from hydrocarbon fuels. Free Water is the collection of H2O molecules in the bottom of gas cans or drums formed when fuel is stored for even short periods of time. The free water formation is due to condensation in the air and/or the separation of water molecules from fuel. Water may be present in hydrocarbon fuels as Free Water or as an emulsion-- small globules of water suspended in the fuel. Water may be emulsified in fuel by vibration or by emulsifying agents such as HEET, alcohol, or detergents. The filter will not remove water emulsified in fuel. We recommend that you filter out Free Water first by using Mr. Funnel, then add such agents to your tank to emulsify any water that may have formed in the tank previously. If both water and hydrocarbon fuels are present in a container and the container is vibrated by shaking or by being transported in a vehicle (including an airplane), water may be temporarily emulsified into the fuel.

Water emulsified in this manner will usually combine and settle out as Free Water in about five minutes after all vibration has ceased. When properly used, the filter will separate this Free Water along with rust and dirt from your fuel.)
