Full Test Of Fuel Filter Funnel from Shurhold Industries - 06/08/2011

The main issue we see in boating is water contamination in our fuel. Since the "Mr. Funnel" claims filtering out water is its main purpose, we started our test by adding water to a jar of fuel. Then we poured the fuel in to the smallest version of the fuel filter funnel to see how it performed.

After filtering the gas and water mix, the fuel streamed into another Mason jar and the water was left in the sump of the filter. We let the fuel settle in its Mason jar and noted no water in the bottom.

We conducted this test seven times, some times we shook the fuel water mixture prior to filtering and some times we did not. Each and every time, filter funnel removed the water.

We have seen many filter products in the past and felt it was time to do a full video test on the fuel filter funnel from Shurhold. With a can of gas, some water, dirt and a few Mason jars, we got started testing the three size versions of this product.

The Debris Test

Pictured is the largest of the 3 filters which we put to the test to see how fast the filter actually is.

Testing the Large, Two-Sump Filter

The last test was with the largest funnel. Since Shurhold said they designed it to filter while fueling, we wanted to see if it could actually keep up with a reasonable flow rate. After all, what good would it be if it is so slow that you take an hour to fuel up?

BoatTEST's Christopher Hughes tests the fuel flow rate of the Mr. Funnel, getting great results.

We placed the large funnel filter over a measuring cup then readied our stopwatch. We started the clock and poured the fuel into the funnel filter from a gas can as fast as we could. Limited by the rate from the gas can, we measured a flow or 4 cups in 15 seconds, or one gallon a minute. Later that day we took the funnel filter to a gas station (that did not allow us to film) and measured a rate of 11.5 gallons per-minute, more than adequate.

In fact, Shurhold claims that this large funnel can flow fuel at the rate of 12 gallons (45 L) per minute, followed by its medium funnel at 5 gal. (19 L) per minute and its small funnel at 3.5 gal. (13 L) per minute.

Our overall conclusion is that with water contamination the biggest issue to boaters, whether in gas or diesel, this product will remove the water. With regard to other contaminants, it will definitely filter out debris, rust ships and sand. Microscopic dust particles which account for the slightly cloudy discoloration of the fuel will make it through the filter.

Shurhold recommends these filter products for gas and diesel fuel, along with heating oil or kerosene.

With all of our test gear layed out, we were ready to filter.  You can see the three different sized filters offered.

Step 1- Mix fuel and water in a Mason jar.  Here you can see the water settling on the bottom of the jar.

Step 2 - Pour fuel with water through the fuel filter.

Step 3- The fuel is filtered from the water and what you are left with is pure fuel.

After filtering the fuel and water through the fuel filter funnels, the water is trapped in the filter sump, as advertised by Shurhold.
