FAQs
What is the recommended filter element for E85 fuel?
For E85, the 40-micron Stainless Steel element or the 6-micron Micro-Fiberglass element are recommended. The 75-micron Stainless Steel can be used as a pre-filter for the fuel pump.
Can I clean the filter element?
The 10-micron paper element is typically disposable. The Stainless Steel and Micro-Fiberglass elements can often be cleaned, though the Micro-Fiberglass is also designed as a disposable, high-efficiency option.
What does the 'Forever Fixed' warranty cover?
The 'Forever Fixed' lifetime warranty covers any defects in materials or workmanship for the product's lifespan.
How do I determine the correct JIC fitting size?
You need to match the JIC fitting size to the corresponding female fitting on your fuel lines or adapter. Common sizes are -6, -8, -10, and -12 JIC.
Is this filter suitable for low-pressure fuel systems?
While rated for high pressure, it can be used in lower pressure systems. However, its high flow capacity is most beneficial in applications requiring significant fuel volume.
What is the micron rating of the different filter elements?
The available elements are 10-micron (Paper), 40-micron (Stainless Steel), 75-micron (Stainless Steel), and 6-micron (Micro-Fiberglass).
Troubleshooting
Reduced fuel flow
Check if the filter element is clogged. Remove and clean or replace the element. Ensure the filter is not installed backward.
Fuel leaks at fittings
Verify that the JIC fittings are correctly installed and tightened to spec. Check for damaged O-rings or seals on the fittings.
Filter rattles or vibrates
Securely mount the filter using appropriate brackets to prevent vibration and potential damage.
Filter element won't fit properly
Ensure you are using the correct replacement element for the 3" filter housing and that it is oriented correctly.
