Hey guys, Chris Fix here! Today, we're changing a flare nut style fuel filter
commonly found on GM vehicles like this Chevy but Toyota Honda and a few other
companies use the same style filter where you need to use a wrench to remove it.
Just like most cars, the fuel filter is located under the car and since the
Vette is so low,
we're gonna go put it on ramps.
And then any time the car goes up on a ramp, make
sure you put a block on the rear tires so doesn't slide backwards.
Now we'll come to the passenger side where the fuse box is.
On the back of the fuse box, it's very
helpful. Fuel pump one, number 14.
We'll pull that.
And you can hear the engine
just stalled out. Perfect!
Alright for the Vette, the fuel filter is right under here on the
passenger side. Get our drip pan ready.
That is the passenger front tire right there,
and if you look right behind the tire, the fuel filter is right up there.
Now this fuel filter is clamped in, and keep it that way
the first thing will do is remove the fuel line from the filter and the clamp
will help us hold the filter in place. Now you have two wrenches you're gonna
need, the larger wrench goes on to the fuel filter itself, while the other wrench, in
this case I'm using a flare nut wrench which if you have one definitely use it
will prevent stripping, and that goes on the flare nut on the fuel line.
Now that's not gonna come off easy so let me show you a trick.
Slide the closed end of
another wrench over the open end of your flare nut wrench.
The longer your wrench, the more torque you're gonna have to remove a nut or bolt.
Now we can hand loosen the nut.
Remember to wear your goggles so gas doesn't get in your eyes
And just let it leak out.
and once it's finished leaking out, we're gonna go remove the fuel filter bracket bolt
Now just slide the bracket out, and remove it.
Now we can seperate the fuel
line from the filter. Notice on the other end of the fuel line is an o-ring.
If your o-ring is dry, cracked, rotted out, replace it so you don't get a fuel leak.
I'm gonna push this piece of paper towel
in the filter to limit the amount of fuel it leaks.
Now we can use the closed-end of the wrench on the side.
And the box end on the other side.
And break this filter free.
One you break it free, you can keep the wrench on the flare nut in
the back as you turn the filter since there's way more room to turn the filter
than the wrench.
And there we go!
So that's our old filter and this is the new one.
Always compare your parts and make sure their the same. If you look at the threads
on the old one you could see after thirty thousand miles, there's some
corrosion which made it hard to come off. So what we're gonna do is get some Anti-Seize on
your finger and get some right in there and some on the other side and rub it
into the threads. This will make it a lot easier to get off in the future.
So when installing our new filter, pay attention to the flow arrow.
We're gonna have to flip this around because the flow's going this way,
through the filter,
up to the engine.
So our flow is now correct.
Now get a wrench on the flare nut, and tighten the filter down by hand.
Good!
Now get your wrench and snug it up.
Good!
Now get your fuel line and push it into the filter.
and hand-screw the flare nut into the filter.
get your one wrench on the filter nut and the other wrench on the flare nut.
and snug it up!
Just like that!
Now that this side and that side are tightened down,
we can get our filter and snake it back over the filter.
So when doing this, one trick
that saves time is always put the screw in the bracket hole first.
Then you could align the bracket,
screw it together,
And tighten it down!
Good!
Now remember to use a marker,
and write down the mileage so you have a record of when your filter was replaced.
Alright, once you finish putting that fuel filter in,
don't forget to put the fuse back in.
It just pushes back in.
Close the cover up.
And lets test it out!
Now don't immediately start the car, turn it to the run position,
wait 2 seconds
then shut it off.
Repeat this twice so the fuel pump fills the filter and builds up pressure.
Now you can start her up and we're gonna immediately check for leaks.
She's leak free so job well done.
