I’m fueling up my boat at a dock I don’t know. How do I protect my fuel system?

 

Can you trust the fuel up station you’re using?

We hear this question all the time, the truth is, even the stations you do know, you may not be able to trust! It’s not that your fuel station is bad, or they’re intentionally neglecting their fuel systems – condensation develops naturally, algae grows from condensation, the interior of tanks erode from age and algae. These factors may not all be rff1controlled by you or your fuel up station but Racor has an answer for your needs.

Pre-Treating or pre-screening your fuel is completely possible with the Racor RFF Fuel Filter Funnel Systems. Available in a wide array of sizes and flow rates, it can’t hurt to pre-filter your fuel before putting it in your tank. The saying we love to use in our blog posts would be: what is more cost effective; a few dollars for a funnel or replacing a fuel injector in the middle of the ocean. We’ll be honest, a single injector won’t shut you down and completely disable you, but taking unnecessary risk doesn’t make sense. Allow us to introduce the RFF Funnel Systems & if you’re in a rush, Click Here to download Racor’s PDF on RFF Funnels:

RFF1C RFF3C RFF8C RFF15C
Max Flow Rate 2.5 GPM 3.5 GPM 5 GPM 12 GPM
Micron Rating 50 Micron 50 Micron 50 Micron 50 Micron
Height 6 in 9 in 10 in 10 in
Diameter 3.5 in 5.5 in 8.5 in 8.5 in
Weight 0.2 lb 0.3 lb 0.6 lb 1 lb

How do the funnels work?

Each funnel comes with a standing, built-in DuPont PTFE (Polytetrafluoroethylene) coated rff2stainless steel screen filter.The screen starts around 1.5″ to 2″ above the base of the funnel allowing a designated area for heavy debris and water to collect so it doesn’t rise above into the screen filter. Water can be filled up to 1/3 the height of the metal screen filter without compromising water from passing through the funnel due to weighted pressure from the fuel.

As we described above, water in fuel is not necessarily from negligence – water can develop due to several factors; extreme vibrations of the fuel can cause molecules to separate, condensation can build up in a fuel tank from heat, and many other factors. Fuel does not have to be months old for this to occur, it can occur to fuel or fuel tanks that are a mere days old.

Which fuel types work with the RFF Funnels?

Any hydrocarbon fuel will allow this funnel to work appropriately. It is not recommended to use this funnel for any other reason than for hydrocarbon fuels (gasoline, diesel fuel, kerosene, jet fuel, etc) because other fluids may have detergents, chemicals or properties that damage or negatively effect the proper filtration for hydrocarbon fuels.

Does Racor make fuel filtration systems for small engines?

Racor Fuel Filtration Systems for Small Engines

Most of us have some type of small engine at our home, place of business or at work; generator, power washer, lawn equipment, work vehicles, earth movers, etc. Racor has a wide variety of filters and assemblies for filtering gasoline and diesel small engines. The 3 assemblies we will be focusing on in this post are all capable of filtering Gasoline and Diesel fuel.

Assembly Benefits and Features:

110A

The Racor 110A is  a metal bowl assembly that can handle a significantly higher PSI fuel system (100PSI/ 690kPa). Being allowed to install on the vacuum and pressure side of a fuel system, there aren’t many small engines this assembly will not be able to handle. It’s replacement elements (R11S or R11T) are also affordable. The assembly measures only 6″ tall and just under 3.5″ wide in both directions making it small enough to attach to any small engine frame.

120A

The 120A assembly is beneficial because of its number of ports, 4 total, 2 in and 2 out which allow you to filter your fuel as well as polish your fuel before being used. Similar in size to the 110A, the 120A  is only 6.5″ tall and 3.2″ wide in both directions. The replacement element for this assembly is the Racor R12 which is available in 2, 10 and 30-micron ratings. This assembly has a clear bowl which makes it easy to see the debris or water build up and when you need to drain the system.

140R

The Racor 140R is unique in the fact that it does not have a mounting bracket. This makes the assembly ideal for application anywhere with hard fuel lines. Finding space on asmall engine can sometimes be difficult so this eliminates the need for a mounting place and can suspend freely wherever you can fit it. Similar to the 120A series, the 140R assembly utilizes the Racor R12.

What Micron Rating should I use for my particular application?

Need help deciding what micron rating to use?

Some of the below, is information that we pulled directly from the Racor 7480G Racor-Parker Catalog on determining Micron size as well as some detailed information on understanding micron ratings.

[box type=”info”]Racor’s 2 micron filter medium should only be used in final or secondary filters where the fuel is first filtered by a primary filter.[/box]

A micron rating for a fluid filter is a generalized way of indicating the ability of the filter to remove contaminants by the size of the particles.  AIR FILTERS ARE NOT RATED BY MICRON SIZE. The micron rating does not properly or fully describe either the efficiency or the  contaminant holding capacity of the filter. What does the word micron mean? It is a unit of linear measure in the metric system used to measure distance from one point to another. It is used like the inch, foot, centimeter and millimeter to measure the length, width, or diameter of objects.

Micron Reference Chart A filter that is marked “10 microns” has some
capability in capturing particles as small as 10-microns. However, there is no one accepted method to measure and describe the size of particles that a filter can capture or the total amount of particles that the filter can hold. When you see the filter marked “10 microns”, you will not know exactly what this means unless you also have a description of the test and standards used to determine the filter rating. Filter micron ratings are often based on one of these methods, but with many possible variations:
A. Nominal Micron Rating (NMR) NMR usually means the filter can capture a given percentage of particles of the stated size. For example, a filter might be said to have a nominal rating of 90% at 10 micron.

B. Absolute Micron Rating (AMR) AMR is a single pass test and is obtained by passing fluid containing glass beads through a flat sheet of filter material. Any beads that pass through are captured and measured.

C. Multi-Pass Beta Rating (MPBR) The MPBR has been accepted by many machinery manufacturers, as well as filter manufacturers (but not used in a public way by most of them to identify or specify their filters), especially for filters used in fluid power applications; hydraulics, controls, transmissions, power steering and so forth. Single/Multi-Pass tests use contaminant specially graded by particle sizes added regularly in measured quantities to the fluid which is pumped continuously through the filter. Measured samples of fluid are taken at timed intervals upstream and downstream of the filter. The contaminant in these samples is measured for particle sizes and the quantity of each size or ranges of sizes.
Some suggestions:
1. Use filters of high quality.
2. Obtain filters by catalog listing, not just by “micron rating”. Other important qualities should also be considered.

3. Pay close attention to service intervals and good service practices for best economy of operation.

[hr]

Racor makes filters with various filtration efficiencies, but its standards for non-OEM (Original Equipment Manufacturer) are 2, 10, and 30 micron filter elements. The actual efficiency ratings for these are 98%, 95%, and 90% respectively. Racor also makes use of a 7 and 20 micron filter medium which are used to meet certain engine manufacturer’s requirements for a final filter and a primary filter. Racor’s 2 micron filter medium should only be used in final or secondary filters where the fuel is first filtered by a primary filter. The primary filter for a 2 micron final filter should use a 10 micron medium. The exception in using a 2 micron filter in place of a primary filter is to obtain high-efficiency water separation, and is usually used in marine applications where the fuel supply may be cleaner but also may contain water more often. If the installation can allow the use of a filter large enough, then a 2 micron filter can serve in a system as the only filter in that system.

Why does my Racor 2020 & 2040 filter have a black end cap?

Why does my Racor 2020 & 2040 filter have a black end cap?

As you are probably aware, if you have previously purchased the Racor 2020 series fuel filter or the Racor 2040 series fuel filter, the end caps are now black when they once used to beige or tan in color. There are several differences which we will explain below and we will also post images of the old and new style filters.

 

Racor 2040tm-OR2040N-10

In order from left to right we have 2040TM-OR, 2040N-10. Racor has almost always used a distinctive coloring system to represent their micron ratings and they still are in a sense, it is just not as obvious as you have seen before. 10-micron has normally been represented by the color BLUE, as you can see if the 1st image, the ink is BLUE and very clear, the new style in the 2nd image is simply printed in Blue ink  lightly. These two products are exactly the same except for the new color scheme Racor has begun to utilize.

All-in-all, should you receive the black capped filter on the right, fear not!
