Types of In-Line Fuel Filters

There are four types of inline fuel filters for automotive use: glass-packed, mesh, sediment bowl and spin-on cartridge. Each one performs the same basic function, but varies in construction and design.

Glass-packed fuel filters

These use a fine glass powder to scrub the fuel of impurities. As the glass degrades, it gets deposited into the bottom of the canister (the sediment bowl), where it must be periodically cleaned out.

Mesh inline fuel filters

They are constructed by weaving semi-permeable metal strands together to create a webbing that catches contaminants as they pass through. The advantage of mesh filters is that their capacity for trapping contaminants increases with micron size.

Sediment bowl inline fuel filters

They use an elevated bowl at the bottom of which is located a filter element made from paper or other fibrous material. Contamination collects on this filter element until it becomes full, at which time the bowl must be drained.

Spin-on cartridge fuel filters

They are the most popular for automotive use. A cartridge that has been pre-loaded with a filtering element is inserted into a metal canister, which facilitates removal of the filter for servicing or replacement.

Buying Guide for the Best Inline Fuel Filter

In addition to being aware of what type of inline fuel filter you need, it's also important to pay attention to a few other factors when choosing filters:

Fuel Type

Most of the fuel filters are compatible with different types of fuel. However, it is advised to check the fuel type that the product is compatible with. Some filters do not support diesel - for instance. The type of filter used in the inline filter also makes a great deal. Understand which type of filter will be suitable for your engine. Consult your mechanic for better guidance.


The reason these filters come in different dimensions is to fit with different engine types. So, it is always advised to understand your engine's dimension and cross-check it with the filter.

Filter Media

There are two types of filter media used: synthetic and natural. Both have distinctive features, like natural filters are anti-clogging, whereas synthetic is for better protection.

Micron size

This is how fine the mesh in your filter is and determines its ability to block contaminants from passing through. The smaller the micron size, the finer filtration capability. For automotive applications, look for a mesh size between 50 and 100 microns. In-line vs Plug-In vs Return-Style In-line fuel filters must be placed between the fuel pump and fuel tank in your vehicle, while plug-in and return-style filters can be installed in any position. In-lines are typically more expensive than other types of fuel filters because they require custom installation and additional parts to connect them to your car's fuel system.

Filter Price

Even though not everything you pay for is "better," it stands to reason that a higher price point on an inline filter will generally indicate higher quality construction with finer mesh materials. However, if an inline model is significantly more expensive than its competitors, there may be another factor at play, such as increased flow rate or some special feature that justifies the higher price.

Filter Flow Rate

In-line fuel filters have a flow rate rating, which determines how much fuel they can process per minute. Higher flow rates mean that your engine will have a steady supply of clean fuel flowing through it at all times and also reduces the likelihood that you'll run into problems caused by clogged filters (which is why regular replacement is so important).

Filter Application

In-line fuel filters are available in a wide range of sizes and constructions. In general, the most common type used on cars, trucks, boats and ATVs is the spin-on filter that screws into place between your fuel tank and fuel pump. However, they also come in several other forms from which you'll have to choose: inline with a strainer built in, inline with a pre-filter for large particles ahead of it or in a return fitting behind your fuel pump to protect it from damage due to dirty fuel.

Price vs Quality

Although many higher priced inline models do offer better construction materials and performance capabilities than their cheaper counterparts, it's still possible to find high quality filters that are priced in the mid-range. With that in mind, don't assume that all expensive filters are superior in quality, and be sure to compare several models before you make your decision.

How Do You Install an Inline Fuel Filter?

With a few clamps and fixtures, you can get started with installing your inline fuel filter. You need to buy these elements by yourself as they don't come along with the filter. Here is the step-by-step guide to install inline fuel filters:

  • Buy any two top-quality inline fuel filters from suppliers.
  • Drain the fuel lines in order to make the entire process a little less messy.
  • Now you need to cut the hose that will be enough for the filter to rest easily.
  • The first inline filter is placed after the metal fuel line that exits the pan in the rear transmission area.
  • The second filter will be inside the engine compartment that comes before the fuel pump.
  • Consider the little arrows on the filter to guide yourself while placing them in the right way. These arrows indicate the flow or direction of the fuel flow.
  • Use clamps to attach the filters tightly and rightly on their places. Clamps also ensure that there is a lesser mess during installation.

It is important to maintain your filter properly that will reduce the timeline of replacing it. Replacing the filter is also extremely important to care for your engine's health. Don't rely on cheap inline filters that can directly affect your engine's performance.

Do inline fuel filters reduce flow?

Inline fuel filters are made to filter the fuel and supply fuel to the engine according to the standard requirement. Many customers have apprehension about inline fuel filters and think they reduce the flow of the fuel.

It is important to note that a filter of proper sizer installed without any partially plugged debris will never restrict or reduce fuel flow to the engine. Any sort of clogging resulting from the lack of cleaning can lead to a reduced flow of fuel.
