Hey Guys ChrisFix here and today i'm going to show you how to replace a fuel filter in a Ford Lincoln Mercury Mazda
Pretty much anything that has this quick disconnect style fuel filter and to change the fuel filter
you'll need one of these quick disconnect tools
they're very cheap they make you life a lot easier
But just incase you don't want to go out and get one of these
I'm also going to show you how to change one of these fuel filters with a pen cap
So lets begin
Real quick, The common question is when should you change your fuel filter
The easy answer to that is check your owner's manual
And look in the back and see what service interval is recommended.
For your specific vehicle, because it does vary
Typically its between 30-50k miles, or once every 5 years or so
Now ill be doing this on my truck here and the fuel filter is located underneath the truck
And as we go under past the frame rail here
And you can see the fuel filter right there
Since our fuel filter is located below the car the one thing you want to do is you want to make sure
that you do this job with almost no gas in your tank, if the tank is filled with gas
the weight of the gas could force fuel out of the lines as your trying to disconnect it
So remember to do this with a near empty tank
So the first step is to look into the owners manual and see what fuse is for the fuel pump motor
and in this case its fuse 23
And we'll start the car
Come to the engine compartment, Find the fuse box
And while the engine is running we'll pull fuse 23 in this case
which will switch the fuel pump off
This will start sputtering in a couple of seconds
Good now we have no fuel pressure we can go take off the fuel filter
for the under car fuel filters don't forget to get a catch pan to catch any dripping fuel
Once your down here you just want to size up your new and old fuel filters and just make sure they're are the same size
and in this case they are. The next step is get your paper towels ready
Make sure you have your safety glasses on
Now take your quick disconnect tool and slide it over the metal pipe on the fuel filter
then take the quick disconnect tool and push it into the fuel line
as you push the fuel line in towards the tool.
Once the tool is in the fuel line, pull the fuel line off the fuel filter
Once the fuel line starts leaking, you can remove the tool
and pull the fuel line the rest of the way off
Now do the same for the other fuel line
Its that easy
Now lets remove the fuel filter so its easier to get to that last fuel line in the front
Now Unfortunately our quick disconnect tool does not fit in here
so were going to have to use a dental pick to pop this open right here
and pull this clip out
with the clip removed this will come right out
so out with our original old fuel filter, In with the new
So then all you have to do is push in the new fuel filter, pop that clip all the way in
And thats secured
Now were going to pop the fuel filter into its clip
And then we'll connect these 2 fuel lines and were done
The top one is the bigger hose and the bottom one is the smaller hose
make sure that they pop in, wiggle them to make sure they're push all the way in
and they are nice and secure
Good ! So real quick if you dont have the quick disconnect tool
and want to give this a try heres a little trick on how you can rig your own tool using a pen cap
Get a pen cap that fits over the fuel filter tube, now were going to be using the stem here
just bend that like so, and you're going to grab some scissors
or something you have and just cut the pen cap
And then cut a slit down the cap so you can press it over the fuel filter tube
Now lets give it a try
now the same process applies as with the quick disconnect tool
Press the pen cap towards the fuel line and push the fuel line towards the pen cap
And there you go
So you can get the job done being little innovative with a pen cap
And now you've seen both methods to remove this fuel filter
lets go start the car
After you're done don't forget to put that 20 amp fuse back in
so the fuel pump will start up. Good !
Back in the truck were going put the key in the ignition
Turn it to the run position
And shut it off after 2 seconds, and then start the car
That will cycle the pump to pressurise the fuel filter and fill that fuel filter with fuel
Remember to go under the vehicle and check it for leaks while its running
and another thing you could do while your under there is get a marker and write down your current mileage
So you don't loose track of when you changed your fuel filter
And thats all there is to replacing the ford style fuel filter
its actually pretty easy with the quick disconnect tool
and for a few bucks its worth every penny to have one
just makes the job that much faster
Ill link this tool in the description for you if you want to get one your self
If not you can always modify a pen cap just like this and it works it just takes a little bit of fiddling
Its not as easy but it can be done
