Which Filter Should I Choose?
Filter: | Micron Rating: | Reusable: | Best Use: | Compatibility: | Notes: |
Cellulose Paper *Discontinued* |
10μm Nominal 92% Efficiency |
No | Post Pump |
Gasoline Diesel |
• Excellent Filtration • Most Economical Element • Most Commonly Used Element • No maintenance, but requires replacing |
Stainless Fine (18-0025-03) |
10μm Nominal | Yes | Pre or Post Pump |
Gasoline Diesel E85* Ethanol Methanol* |
• Excellent Filtration • Superior Compatibility with all fuels • Requires occasional cleaning to maintain optimal flow rate |
Stainless Coarse (18-0025-04) |
100μm Nominal | Yes | Pre Pump |
Gasoline Diesel E85* Ethanol Methanol* |
• Excellent prepump filter for any application • Low pressure drop prevents pump cavitation • Superior compatibility with all fuels |
Microglass (18-0025-05) |
6μm Nominal 99.9% Efficiency |
No | Post Pump |
Gasoline Diesel E85* Ethanol Methanol* |
• Excellent Element for all Applications • Newest advanced technology offering the highest filtration efficiency available on the market • No maintenance, but requires replacing |
* Alcohols may reduce service life if poor quality fuel or excessive water absorption is present. To prevent, use high-quality fuel mixtures and purge alcohol fuels from the fuel system when the vehicle is stored for long periods. |

Flow Data
The chart below shows the results of Radium’s in-house flow testing of these elements in the Radium fuel filter housing. The pressure drop was found by measuring the inlet and outlet pressures at different flow rates.
