We're having a Clearance Sale on this NEW Racor model MD57 diesel fuel filter/water separator for all applications up to 80 GPH or 440 HP.
The unique filter head has inlet/outlet ports to an integral thermal control valve (TCV) which controls the flow of return engine fuel either to recirculate back to the filter or back to the fuel tank. The TCV uses the heated engine return fuel to mix with incoming fuel. This action heats up the fuel filter to provide excellent cold weather protection against fuel gelling. A great benefit to those using Biodiesel, WVO and straight VO as well. The TCV opens at <15 ºC / 60 ºF and closes at 30 ºC / 90 ºF. The settings of the TCV are not adjustable.
You can also use the MD57 as a ‘standard’ unit without using the TCV feature, just plug the left side ‘Fuel Out to Tank’ (<-T) port, and the right side ‘Return Fuel from Engine’ Inlet (E<-) ports with the two (2) provided plugs. By-passing the TCV will allow the unit to work as a standard inlet/outlet type filter.
All fuel ports are metric M16 X 1.5 (ISO9974). The fuel ports from-and-to the fuel tank (T) are all on the left side -facing the unit below. The ports to-and-from the engine (E) are on the right side. Four (4) adapters are provided to convert the metric M16 ports to 3/8”NPTF female pipe threads and two (2) port plugs are provided if you choose not to use the TCV feature. We also include a listing of adapter fittings you can source from a nationwide manufacturer. Call the regional toll-free number to find a dealer closest to you.
The head also features a hand operated fuel priming pump. To vent trapped air, an air vent plug is also fitted. You can mount this filter on the vacuum or pressure side. Do not exceed 100 PSI (6.8 bar) on pressure side applications.
Note: The 10 micron Volvo element sold with the unit is not available for replacement as it is European OEM specific.
The ‘325’ Series reusable contaminant collection bowl features a self-venting drain and water-in-fuel (WIF) probe. The WIF probe must be used with a Racor water detection module (amplifier) to work properly. Order this from Racor
Note: Do not hook this probe up to live power! You must use the special Racor module as the WIF is used to measure ohms of resistance within the fluid. Also, you do not have to use the WIF and may install a ½”-20 drain plug instead. The Racor filter will work without this feature installed. If you do decide to use the WIF probe, cut off the special round connector (there is no aftermarket connector available) at the end of the harness and expose the two wires within the black ribbed tubing. Either wire may be hooked up to the Racor module (no polarity).
