Video tutorial on how to replace the fuel filter on a 1st generation Toyota Tacoma. This particular truck I am working with here today is a 2001 4×4 model and a similar procedure also applies to the 3rd generation Toyota 4Runner as well. A plugged or dirty fuel filter can cause hard starting, loose of engine performance, poor fuel economy, idling issues, and in a serious situation the engine will not start. As a general interval, the fuel filter should be replaced at every 40,000km or 25,000 miles

Tools/Supplies Needed:
-3/4” wrench
-9/16” line wrench
-10mm wrench
-drain pan
-safety glasses
-new fuel filter
-cardboard
-interlocking pliers

Procedure:
-start with removing the electronic fuel injection, EFI for short relay which is located under the hood in the distribution box behind the batter on the driver’s side
-turn the engine over as if you’re starting the vehicle to ensure you have pulled the right relay, this will also help bleed any pressure in the system and reduce the chance of fuel spraying out when we disconnect the fittings on the fuel filter
-going under the truck, the filter is roughly under the driver’s side floor pan, for this truck it’s right next to the transfer case
-a 3/4” wrench is needed for the fuel filter and 9/16” line wrench is needed for the line fitting
-once the fitting has been removed to some extent, fuel will run out so have a drain pan ready as well
-do the same for the other side, again using the same wrenches
-use a 10mm wrench to remove the bolt for the filter clamp
-open up the clamp slightly, then you’ll need to flex the lines to get the filter removed
-compare the old and new filters to ensure they are the same
-directional markings should be on the new filter such an in stamp and flow arrow like this filter has
-the flow arrow should point towards the front of the truck and the in side is coming from the fuel tank
-install the filter in place, I start with threading on the one fitting first
-while it’s not fully tightened just yet, install the other fitting
-push the filter in place, the lines may have bent slightly during removal so you may need a little extra force to assist it into position
-when the filter clamp was opened, this may make it hard to put back together
-so use interlocking plier to pull the clamp together and then thread the bolt into place
-use the wrench to tighten up the clamp bolt
-finally tighten both fittings with the two wrenches
-reinstall the relay we removed earlier for the EFI system
-operate the key a couple times to allow the pump to build up pressure
-check for any leaks
-then start the engine, this may take a little longer when trying to start the engine as the air needs to be bleed from the fuel system
-once the truck is running, inspect the fuel filter for any leaks. If a leak is found, you may either need to reseat the fuel filter or tighten the fittings slightly more
