Hey everyone. So my Mark is currently sitting on a jackstand in my drive way with the wheel, and wheel house off the car. I got the clips out of the fuel lines on the top and bottom of the filter, but for some reason, the filter wont come out of the fuel lines for some reason, its stuck. I'm wondering if there's some twist/pull/squeeze combination that I need to do to get them to release, or if I just need to pull harder? It looks like a factory filter that's never been replaced, so I'm sure that isn't helping the situation at all, but if you could give me a hand, that would be much appreciated! :D
 
I have not done my mk8 filter in awhile so just shooting what i know. Ford uses couple ways to link fuel parts together. If yours uses the plastic "horseshoe" pull off C clips then filter is ready to be pulled off. If yours is the circular type that no clip gets removed you need the "push lock" tools to remove filter.
 
Once you've removed the white plastic clips, the lines should just pull off. Be careful not to twist or kink the lines.

Thanks guys, they ended up popping off, with a little extra force. Turns out it was indeed the factory installed filter with 174k miles on it!

After getting it off, I went and shook it over a glass jar, and what looked like coffee came out! I blew through it, and there was almost zero flow whatsoever, so hopefully, this and the K&N will increase my mileage slightly!

More than just 'slightly'... changing mine did (no K&N though).

Plus, that should extend the life of your fuel pump too...
 
Good, I hope so. Right now it says average is 16.5 around town. We'll be taking a highway trip back to MA this weekend to visit friends, so hopefully, with the cruise set at 70, it'll average at least 20.
 
Seafoam.... how does that stuff even work? I've seen videos and such of people using it, and its just a smoke show.

It can be used in many ways. In the crankcase oil,in the gas tank and siphon into intake track thru a vacuum line. FYI don't let whole can get sucked into vacuum line you can hydrolock engine. Someone here has done that and killed engine. The sucking in thru vacuum line acts like a steam cleaner inside the cly while its boiling off,steam cleaning off all the carbon in there.

16.5-17 is right about were they're supposed to be at. My trip last week I got 25-26mpg 75% highway.
 
Oh, good to know. Thanks for the mileage info.

I may seafoam the engine down the road when I do plugs and boots. Maybe I'll get some of the stuff to dump in the tank.
 
I can honestly say that every time I've seafoamed any of my vehicles, they seem to run quite a bit smoother afterward. That's good stuff. I've never used it in the crank case, but I've used it in the gas tank and through the intake. It works wonders!
 
I didn't find it anywhere, it was on their website directly. Its almost like that 3 step 3M fuel system cleaner. Attach the nozzle straw thing, remove the air tube from the TB, stick this straw at the 12'oclock position at the TB, reattach the air intake tube, hold it at around 1500, and hold the button on the can, spraying it into the TB. You would need two people, but that's the basic idea.
 
Used it. Loved it. Ran Better. Sucked through the top vacuum port. Averaged about 22MPG. Also changed plugs with some E3's Runs a lot smoother. That along with the air intake modifications, car flies down the highway smooth.
 
+1 "right on the mark".
I almost put the whole can of seafoam through the vacuum line off the brake booster. The engine started stumbling like gasping for air then I shut it off took the key out and the motor was still running and stumbling !!!! I tried restarting it a few times and finally she turned over.

I think I was only moments away from a rebuild !

Good to know. So do you use the spray stuff through the intake?

I've never seen the spray. I just use the metal bottle and put a vacuum hose in the bottle and let the engine suck about half the can into the intake through the unused vacuum port in the center of the intake (on GEN1's). It's a lot easier than trying to pour it in through the brake booster vacuum hose.
