Fuel Filter/Water Separator
High Pressure Fuel Filter / Water Separator – Racor 110A Series

The Racor 110A Series is a compact two-piece, all aluminium fuel filter water separator assembly with a cartridge-type filter element that is ideal for use in gasoline/petrol and diesel engines equipped with high-pressure injection systems. It can be installed on the vacuum or pressure side of a fuel pump (up to 100 psi /6.9 bar) with a maximum flow rate of 15 gph (57 lph) for diesel fuel and 35 gph (132 lpm) for gasoline/petrol.

The compact size and four-port versatility make the 110A Series a popular fuel filter/water separator for small engine applications. The filter features 1/4˝- 18 NPTF (SAE J467) inlet and outlet fuel ports and a unitized mounting bracket. Its two-piece, powder-coated die-cast aluminum construction ensures long life and reliable service regardless of the environment.

To service the 110A filter assembly, just spin off the bowl from the mounting head. Collected water can be drained from the ½”-20 UNF bolt. Inlet and outlet ports are available on either side of the unit. Fuel enters the inlet and travels inside-out through the cartridge filter assembly. Any collected water falls down through the center of the element, while fuel continues through the filter to the outlet.

  • Diesel and Biodiesel Engines
  • Gasoline / Petrol Engines

The Racor 110A filter unit comes fitted with a R11T cartridge, 10 micron high-capacity Aquabloc® II replaceable filter element. For 2 micron version see Racor 110A2. Typical applications include smaller diesel and petrol engines used in generator sets, pressure washers, and similar equipment. It’s compact size fits tight mounting locations and 4 ports offer installation flexibility.


  • Prevents costly injector damage and increases operational life of downstream filters.
  • Removes water that enters the system through condensation in the fuel tank. Any water in the fuel stream will support bacterial growth, which can cause clogged filters and result in the formation of corrosive acids. Susceptible components then rust and corrode, leading to erosion and wear of critical fuel system components.
  • Removes hard particles present in air that are introduced during fueling, such as sand and silica.
  • Removes soft contaminant particles from overheated and degraded diesel fuel, which coat filters with black asphaltene-like substance, leading to power loss and engine shutdown.
  • Saves time and money by eliminating unplanned maintenance and unscheduled downtime from system component failure.
  • Servicing is made easy by the spin-on bowl assembly and simple cartridge filter removal procedure.
