The Racor Fuel Filter Funnel (RFF) family is a new heavy-duty, fast-flow, filter-in-a-funnel that separates damaging free water and contaminates from gasoline, diesel, heating oil, and kerosene.

200 Series Fuel Filter/Water Separators

The 215R, 230R, and 245R fuel filter/water separators come standard with an integral priming pump and a new see-thru contaminant bowl which can operate in applications up to 30 PSI. Another design upgrade is the optional 200-watt in-bowl heater for colder operating conditions. Applications include light-duty and medium-duty trucks and vehicles, construction, agricultural, and other diesel-powered equipment.

All 400 Series spin-on fuel filter/water separators feature a hand (palm) operated fuel priming pump which simplifies service procedures and yields extremely low flow resistance due to its unique pump bypass characteristic. These filters also feature multiple fuel ports (two inlets and two outlets) and a unitized mounting bracket for installation convenience.

Inlet and outlet threads are 3/8”-18 NPTF (SAE J476) for the 445R, 460R, and 490R, and 3/4”-16 UNF (SAE J1926) for the 4120R. These filter assemblies provide flexibility during mounting to fit any engine application.

Additional 400 Series features include spin-on, high-capacity, Aquabloc®II replaceable filter elements which stop water, remove solid contamination, and are available in 2, 10, and 30 micron. Filtration needs should be based on application, fuel quality, operating climates, and maintenance schedules.

Also included are spin-on contaminant collection bowls. The clear bowls used with these filters will not discolor from alcohol, additives, or UV light and have a leak-proof, positive seal, self-venting drain for easy servicing. Water and contamination levels can be seen easily at a glance.
Options for the 400 Series filters include: water detection kits (for diesel applications only), vacuum or compound gauges, and 12 or 24 volt dc, 200 watt fuel heaters.

Turbine Series filter assemblies are designed to be installed on the vacuum side of the fuel transfer pump for best efficiency and protect precision engine components from dirt, rust, algae, asphaltines, varnishes, and especially water, which is prevalent in engine fuels. They remove contaminates from fuel using the following legendary three stage process:

Stage One: Separation
As fuel enters the filter assembly, it moves through the centrifuge and spins off large solids and water droplets which fall to the bottom of the collection bowl.

Stage Two: Coalescing
Small water droplets bead-up on the surface of the conical baffle and cartridge element. When heavy enough, they too fall to the bottom of the bowl.

Stage Three: Filtration
Proprietary Aquabloc®II cartridge elements repel water and remove contaminants from fuel down to two micron (nominal). They are waterproof and effective longer then water absorbing elements.

Features and Benefits:

  • Available in several sizes to fit any application.
  • Heavy-duty construction.
  • Installs quickly.
  • Available in 2, 10, and 30 micron.
  • Easy to service.
  • Clear collection bowl.

Alternative Fuel Filtration

These assemblies are designed and tested for today’s new alternative fuels: Compressed Natural Gas (CNG), Liquid Natural Gas (LNG) and Liquid Propane Gas (LPG). CNG, LNG and LPG have the same problems that plague diesel and gasoline, particulate contamination collects during handling, water condenses in tanks, and compressors leak oil into the fuel stream.

The precision components necessary for the efficient operation of an alternative fuel system demand superior filtration. Racor anticipated the need for ultra-fine filtration at the pressures required by compressed natural gas. The answer is the industry’s first, most complete and most efficient line of alternative fuel filters/coalescers.

FFC series filters are designed to protect critical engine components in CNG, LNG, and LPG powered vehicles. Contaminants can be introduced into a vehicle’s fuel tank when being fueled or may come from compressors and/or storage facilities. A grade 6 coalescing filter is specifically designed to remove oil, water, and solid contamination from compressed natural gas. The patented coalescing filter removes 99.97% of all aerosols in the 0.3 to 0.6 micron range.

These fuel filter/coalescer elements are produced by a patented process of arranging micro-glass fibers into a tubular form. During operation, fuel is forced through the coalescing media from the inside of a cartridge through a tubular wall to the outside, where large droplets fall to the bottom of the housing. Oily water emulsion accumulates until drained while dirt particles remain trapped and collect on surfaces of fibers.


Algae-X cleans your fuel system by simply running the engines!

Fuel is naturally unstable. Its quality and chemistry are continuously degraded by transportation & storage from refinery to user, oxidation, heat & pressure of engines, pumps & injectors, and by water & microbial contamination. Even when fuel is still clear and bright, microscopic fuel components agglomerate forming larger clusters and organic compounds. Eventually, filters clog and sludge (algae, gum, tar, varnish, wax, etc.) accumulates in storage tanks. Algae-X Technology reverses the agglomeration process.
