Frequently Asked Questions (FAQs)

1. Are bigger fuel filters better?

In the case of a fuel filter, too small can cause problems but there's really no size limit for too large. There's no need to go overkill on a filter as long as it provides adequate protection.

2. Do performance fuel filters make a difference?

In theory, a less restricting fuel filter could cause the fuel pump to use less electricity, and therefore reduce the drag on the alternator. This is the only performance benefit I can see a better fuel filter could have on an otherwise unmodified vehicle. However, this effect is extremely minimal.

3. What micron filter is best for diesel fuel?

Usually, a 10-micron filter is used for unleaded gasoline, and a 30-micron filter is used for diesel fuel. A 30-micron filter used in an unleaded dispenser unit can allow unwanted particles to pass through to the customer's vehicle.
