Fuel filters are connected to fuel lines, which are metal tubes that connect the engine and the fuel tank. There are two types of fuel line filters: inline filters and cartridge filters. Inline filters are made of metal or plastic and are connected to a fuel hose, with an inlet connected to the inside of the fuel pump and an outlet on the outer side. Cartridge filters consist of a replaceable bowl that contains filtering paper or synthetic material. It is important to connect the fuel lines to the correct tubes, as they may have slightly different diameters.

There are two connectors (metal tubes) on one side of the filter, with one tube on the other side
There are two types of fuel line filters. An inline filter is made of metal or plastic units and is connected to a fuel hose. These filters have an inlet connected to the inside of the fuel pump and an outlet on the outer side. This filter usually connects the engine and the fuel tank. The other type, cartridge filter, consists of a replaceable bowl that contains filtering paper or synthetic material.
The inline filter has two connectors (metal tubes) on one side of the filter, with one tube on the other side. The tubes are different diameters, so the fuel lines should be connected to the tubes that they fit on.
The cartridge filter, on the other hand, has a single inlet and outlet. The inlet is connected to the fuel pump, and the outlet is connected to the engine.
It is important to note that the fuel filter should be installed correctly, with the inlet connected to the fuel pump and the outlet connected to the engine.

There are two types of fuel line filters. An inline filter is made of metal or plastic units and is connected to a fuel hose. These filters have an inlet connected to the inside of the fuel pump and an outlet on the outer side. This filter usually connects the engine and the fuel tank. The other type, cartridge filter, consists of a replaceable bowl that contains filtering paper or synthetic material.
There are two connectors (metal tubes) on one side of the filter; one on the other side. One tube has a slightly different diameter, so put the fuel lines on the tubes that they each fit on.
To identify which fuel line goes where, follow the fuel lines carefully. The route of the fuel lines and fuel flow goes: from the tank to the fuel pump on the engine in the upper hose to the pump that appears to come from under the firewall, then to the fuel filter in the lower hose from the pump to the right-hand side of the fuel filter, then through the filter and out on the left-hand side to the short black hose that heads down.

An inline filter is made of metal or plastic units and is connected to a fuel hose
There are two types of fuel line filters. An inline filter is made of metal or plastic units and is connected to a fuel hose. These filters have an inlet connected to the inside of the fuel pump and an outlet on the outer side. This filter usually connects the engine and the fuel tank. The inlet and outlet are connected to tubes, which are usually metal, and these tubes are connected to the fuel pump and the engine or fuel tank.
The other type of filter is a cartridge filter, which consists of a replaceable bowl that contains filtering paper or synthetic material. If you wish to change the filter, you can unscrew the bowl and change the filter.
It is important to ensure that the fuel lines are connected correctly to the filter. There are usually two connectors on one side of the filter and one on the other. The connectors are tubes, and one tube is usually a slightly different diameter to the other. The fuel lines should be connected to the tubes that they fit on.
If you are having trouble separating the filter from the line, you can try spraying the connection with a lubricant such as PB Blaster.
