Radium - High Flow Fuel Filters
The Radium Engineering universal fuel filter is a perfect match for any application needing high flow and industry-leading filtration. Radium Engineering uses one of the largest filtration elements in the industry. This translates into a long service life and minimum flow loss, making this filter perfect for low and high-horsepower applications. The filter can be completely disassembled for servicing and replacement elements are available. Stainless steel mesh elements can be cleaned and re-used, while the microglass element must be replaced at the end of it's service life. The filter is designed for EFI fuel pressures and can be safely used on a high pressure fuel feed line.
RADIUM IN-HOUSE TESTING
Burst Pressure: 750psi
FILTER CONSTRUCTION
All fuel filters are constructed with a 3-piece body that is CNC machined from 6061 aluminum and Type-II anodized for maximum corrosion resistance.
The end caps are sealed to the body with FKM O-rings.
As shown below, the filter elements feature a stainless internal core to prevent collapsing at high flows.
The fuel filters come preassembled with the chosen filter element. These filters are compatible with all fuel types including gasoline, diesel, methanol, ethanol, and alcohol blends such as E85. High fuel pressures < 150psi can safely be used with negligible pressure drop.
TYPES
Besides the filter element differences, there are 2 types of Radium Engineering fuel filters. The 20-0220-0X fuel filters (shown below) are represented with an anodized green outlet cap. This is a high flowing version of a typical fuel filter on the market amd is suitable for all fuel types.
The 20-1220-0X fuel filter (shown below) is represented with an anodized silver outlet cap and contains a one-way check valve.
These fuel filters use the same elements and have the same phyical dimensions as the 20-0220-0X fuel filters. The difference is they feature an integrated check valve on the outlet. This filter was flow tested to have a 1psi drop at 300LPH and 2.5psi drop at 700LPH.
Depending on the application, the check valve fuel filter can be used to prevent pressure at the fuel rail from dropping when the engine or fuel pump is turned off. As an example, some fuel pumps do not include a back-flow check valve on the outlet. Another example is some venturi jet pumps operate on the high pressure side rather then on the return side of the fuel system. These examples would result in loss of line pressure when the pump is turned off and could therefor benefit from a check valve fuel filter. Keeping pressure in the fuel rail helps speed the restart cycle of the engine.
ADAPTER FITTINGSAll fuel filter end caps are removable and feature large -10AN ORB female threaded ports for high flow plumbing. For a list of available adapter fittings, go here:

DIMENSIONS
The dimensions shown below are the same for all fuel filters.
ELEMENT SELECTION
The Radium Engineering fuel filters are available with different filtration elements. Each option is discussed below.
ABSOLUTE: 99.9% of the particles larger than the specified micron rating will be trapped within the filter.
NOMINAL: The majority of the particles within the specified micron rating will not pass through the filter.
The official BOSCH Fuel Injector filtration specification states:
"Recommended filter quality: nominal rating 5um, minimum 82% capture efficiency according to ISO/TR 19438; dirt particles > 35um are not permissible."
The Radium Engineering 18-0025-05 element (from 20-0220-05 filter) has a capture efficiency of 99.9% at 6 micron meeting this standard.
MOUNTING OPTIONS
20-0221 1pc Clamp, 60mm, Heat Exchanger
With engine power levels globally increasing, pump heat is fast becoming an issue in fuel systems. This custom extrusion includes cooling fins that help dissipate heat. The conductive 6063 aluminum design directly clamps to the fuel filter body with 2 countersink stainless steel screws.
For maximum efficiency, this unit must be mounted in a location where cool air can pass through the cooling fins, such as underneath the vehicle. Four M6x1mm stainless steel screws are included for mounting to the chassis. The unit is anodized black with a laser engraved design.
20-0218 2pc Clamp, 60mm, SingleThis 6061 billet aluminum 2-piece clamp consists of two halves that grip the filter body.
Three stainless steel M5 bolts are used to mount the clamp to the vehicle and two additional screws are used to secure the clamp halves together. The clamp is anodized black with a CNC engraved logo.
20-0122 2pc Clamp, 60mm, DualThis 6061 billet aluminum clamp is designed specifically for 2 filters (or 1 filter and 1 Bosch 044 pump). A stainless steel M8 bolt and lock nut is included.
This clamp must be mounted to a flat surface. The clamps are anodized Radium green with laser engraved logos.
