Installation Instructions

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 both carbureted and EFI fuel pressures.

Burst Pressure: 750psi

The fuel filter is 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.

Both removable end caps feature large -10AN ORB female threaded ports for high flow plumbing. Radium offers a large selection of adapter fittings to connect up to a variety of fuel hose types and sizes.

For a list of available adapter fittings, go here: ADAPTER FITTINGS. 

The Radium filter element has an extensive amount of surface area in order to extend service life. Keep in mind that high fuel demand engines will experience an increase in pressure drop faster as the contaminant load increases in the element. This means service intervals will be more frequent with higher powered engines.  

For element media servicing, just the green outlet cap is required to be removed.

The fuel filter comes 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.


The Radium High Flow Fuel Filter is available with different filtration elements. Each option is discussed below.

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 6 Micron Microglass element has a capture efficiency of 99.9% at 6 micron meeting this standard.

As shown below, the elements feature a stainless internal core to prevent collapsing at high flows.

The chart below shows the results of Radium's in-house flow testing of the fuel filters. The pressure drop was found by measuring the inlet and outlet pressures at different flow rates.


1pc Heat Exchanger Clamp, 60mm

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.

2pc Dual Clamp, 60mm
This 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.

2pc Single Clamp, 60mm
This 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.
