Guide overview

Before you begin

This repair is an easy repair for a beginner that is wanting to work on their own vehicle. However, there are a few things to be cautious of before making this repair. Make sure your fuel lines are not dry rotted leading to a crack and beginning to leak fuel when working on the fuel filter. If so make sure you buy the adequate parts before beginning so you do not have to have to repeat the repair to get the vehicle running properly.

Step 1

Repair step

⌕

Before getting under the vehicle to begin replacement. Apply the emergency hand brake to prevent the vehicle from rolling.

Step 2

Repair step

⌕

Locate the fuel filter under the passenger side of the cabin, mounted on the inside frame rail.

Step 3

Repair step

⌕

Place a drain pan underneath the fuel filter to collect any excess fuel that leaks from the fuel filter and lines during disassembly.

Step 4

Repair step

⌕

Using the 10 mm socket wrench, loosen the bolt on the clamp that holds the fuel filter in place.

Step 5

Repair step

⌕

Using vice grips, apply them to the fuel lines on both sides of the fuel filter before removing the hoses. This will prevent any excess fuel from leaking out of the lines.
Remember to leave about 4 inches of room to slide the hose clamps off the fuel filter fitting.

Using a flat head screw driver, work loose the fuel line if it has been on the fitting for many years. Using your hands or a pair of pliers gently rotate and pull on the line to remove the fuel line completely from the fitting.

Step 9

Repair step

⌕

Remove the old fuel filter from the clamp in which it should slide out since it is already loose.
