Hi,
Regarding Fuel Filter - Under vehicle, driver side, below seating area, front
of fuel tank, mounted on chassis in fuel line.
A device located in the fuel line to remove impurities from the fuel before it enters the carburetor or injector system.
INSPECTION
Fuel filters can be located in a fuel line, in the tank, in a
carburetor, or in any combination of these. A carburetor often has a
filter behind the fitting at its fuel inlet.

Fuel filters that are installed on the outlet side of a fuel pump are called outlet filters.

Engine heat causes fuel to vaporize, which can result in vapor lock
in the filter. Some fuel filters have vapor return lines to allow for

Fuel injection systems require larger, heavier duty filters than
carburetors. They filter out smaller particles of dirt while still
allowing the pump to supply a substantial amount of fuel.
REPLACE
Fuel filters and elements are serviced by replacement only. Some
vehicle manufacturers recommend fuel filter replacement at 30,000 miles
(48,000 km). Always replace the fuel filter at the vehicle
manufacturer's recommended mileage.
The fuel filter replacement procedure varies depending on the make
and year of the vehicle and the type of fuel system. Always follow the
filter replacement procedure in the appropriate service manual. The

Connect the fuel pressure gauge to the Schrader valve.
Install the free end of the gauge bleed hose into an approved gasoline
container, and open the gauge bleed valve to relieve the fuel pressure.
The remaining steps are :-
Place the vehicle on the hoist and position the lift arms according to manufacturer's recommendations. Then raise the vehicle.
Flush the fuel filter line connectors with water, and use compressed air to blow debris off and away from the connectors.
Follow the recommended procedures for disconnecting the fuel inlet connector.
Follow the recommended procedures for disconnecting the fuel outlet connector, then remove the fuel filter.
Installing Fuel Filters
In-line fuel filters are installed in the fuel line. In carbureted
engines, the in-line gasoline filter is usually installed between the
fuel pump and the carburetor. In vehicles with a fuel injection system,
the location of the fuel filter is determined by the manufacturer. An
arrow on the filter shows the direction of fuel flow.To install a new filter, begin by wiping the male tube ends of the new filter with a clean shop towel.
Apply a few drops of clean engine oil to the male tube ends on the filter.
Check the quick connectors to be sure the large collar on each
connector has rotated back to the original position. The springs must
be visible on the inside diameter of each quick connector.Then install the filter in the proper direction and leave the mounting bolt slightly loose.
Install the outlet connector onto the filter outlet tube and press
the connector firmly in place until the spring snaps into position.Grasp the fuel line and try to pull this line from the filter to be sure the quick connector is locked in place.
Then, do the same with the inlet connector.
Now tighten the filter retaining bolt to the specified torque.
Once everything is connected, lower the vehicle, start the engine, and check for fuel leaks at the filter.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
