Smaller is much better and filters of 5 microns absolute is preferred. A particulate of 40 microns will not go thru an injector and will cause permanent damage.
How many microns is a good fuel filter?
Fuel system pre-filter (before the pump): 25 to 400 micron. This filter needs to protect the pump from damage. Fuel system final filter (after the pump): 1 to 40 micron. High-performance fuel injector manufacturers recommend a 10 micron or finer filter.
Which is finer 10 micron or 30-micron?
Filters with a larger micron rating allow larger particles through the system. 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.
Is a 30-micron fuel filter good?
Racor says a 10-micron can be used as a primary filter for fuel that is known to be of good quality. Yanmar recommends a 30-micron primary filter regardless of fuel quality for use with the 2-micron secondary filter on its new electronic engines.
How many microns is a cat fuel filter?
Unsurpassed Component Protection – With the ability to capture particles four microns in size and smaller, Cat Ultra High Efficiency Fuel Filters trap and hold contaminates to provide the protection necessary to achieve the designed life of components.
How many microns is a WIX fuel filter?

What is the micron rating on a diesel fuel filter?
The filter media in a Diesel Care Fuel Manager primary filter is rated at 30 micron. A micron is a unit on length equal to one millionth of a metre, or to break this down further; one micron is one thousandth of a millimetre. So, a 30 micron filter will remove particles the size of 30 x 1,000ths of a millimetre.
Is a 20 micron filter good?
The pores of a 20-micron filter are double the size of a 10-micron filter and best for large debris. Any particle smaller than 35 microns is too small to see without a microscope. The particles filtered from a 25, or 20, or 10 are invisible to the naked eye.

What type of filters are used in a diesel fuel system?
Diesel fuel must be filtered not once, but several times in most systems. A typical system might have three stages of progressive filters–a filter screen at the tank or transfer pump, a primary fuel filter, and a secondary fuel filter. In series filters, all the fuel goes through one filter and then through the other.
Is 10 or 25 micron filter better?
Yes 10 micron delivers more transparent water than 25 micron, but a working 25 micron filter is more effective than a non-working 10 micron unit on bypass — i.e. doing nothing at all.
Are all diesel fuel filters the same?
Most diesels have two fuel filters: a “primary” filter located between the fuel tank and the engine, which cleans the fuel before it gets to the fuel transfer pump; and a “secondary” filter up near the engine, which gives the fuel a final cleaning before it gets to the fuel injectors.
What is a primary fuel filter?
The mission of a primary fuel filter is to capture, separate and store contaminants, be they biological, asphalt or water based. Toward that end, the most effective primary filters typically possess some or all of the following attributes: • They must be easy to service, preferably without using tools. •
Does cat 1R 0750 separate water?
Caterpillar 1R-0750 is a fuel filter, not a suction filter. Does this CAT filter separate water correct? Yes, but 1R0750 doesn’t have a drain on it.
