6.4 Powerstroke Fuel Filter Change! DIY Instructions 

The person from Ford that designed the location of the primary filter should have to change them all day long every Friday for the rest of his life.

Taylor. Excellent videos on the 6.4L. When I open my drain separator, I attach a long clear tube to the barb where the fuel drains from. And stick the other end in a container. With this set up, keep the stop cock open when you ratchet off the cover. As soon as you loosen the cover just enough to break the seal on the o-ring, you will get another flow of fuel coming out the line. Spillage from the canister itself is inevitable being that they decided to lay it horizontally. But this will reduce that somewhat. Also stuff some rags under the canister when unscrewing. Keep up the good work.

you make the best 6.4 vids out there i have an 08 f350 4x4 non dually thats deleted with an h&s and it has 340k miles and never been in the shop exept a tranmission but i do all the mantanance myself

Excellent video, just what I was looking for, without a lot of useless rambling. Thanks

Shit like this is why peoples 6.4s blow up cuz they DONT do the proper PMs on their shit. Good job bro

Crazy as it sounds the local diesel guy wants $480 to do an oil change and filters and it's the easiest thing you can do on a 6.4

The tab that stops the filter from rotating and the corresponding hole is why you should always run rotorcraft filters.

Nice vid Taylor I just did this to my truck a couple thousand miles ago. It’s way cheaper to do it at home then go to ford and have them do it. Only down fall is you take a bath in diesel. Lol. I do a Oil change every 5000 and fuel filter every 10,000. Good vid. I like the idea of the water bottle I tried draining into a 5 gal bucket. Rip me

No that sheathing you call it is a fabric membrane for keeping water out which is very important. . Every body knows what happens to injectors when water gets in them! !! That is why I always use OEM ford filters. ..

Thanks for the positive input for the 6.4

Thank you so much for posting this helpful video. I have a 2008 F350 an your video helps me to remember the process.

I can tell you that the lower filter was the wrong one for your truck. The paper looking material over the Ford filter is a water block. It keeps water from being drawn into the filter and stay in the housing for draining.

Only Motorcraft filters, fuel and oil. I also use Motorcraft 15w-40 oil.

Is all 6.4s the same for the 250, 350, and 450? Also, seen you have a egr delete. What kit did you use?

How did you bleed air without opening the schrader valve?

1. check the drained fuel for water 2. make sure you at least put fuel on the or ring

What i normally do when changing my filters is, I loosen the upper, move to the frame rail, change it out with new filter o-ring, put excess diesel fuel on the o-ring, install. Move to the top, new filter/o-ring as well, excess fuel on the o-ring, before i install the new filter, i have someone turn the key on and let the fuel pump fill the upper filter housing with fuel just below the threads on the housing and then screw down the filter and torque it to spec. has worked for me this way and has never failed, nor made a mess. Always rule of thumb on the powerstoke engines. USE Motorcraft filters for the oil and fuel, never cheap out on buying the other brands. The factory filters are designed for the application for the engine. That was a big no no using that wix filter on the fuel system or even on the oil system. I know for a fact that people have had issues with those aftermarket oil filters, mainly because they come with a pre-made cap attached to the oil filter and have seen them blow the cap off because it was not the correct thread pitch and diameter. As long as you stay on your maintenance for these engines and do not use it for a race car type situation, this engine will last you for well over 400K miles. Key thing here is Maintenance for any engine. Change your oil, fuel, & air filters and fluids and your vehicle will last you for a very long time. Nice video Taylor, I have a 08 F250 w/ 6.4 as well and love my truck, but had kinda wish that i had gotten at least a F350 dually or even the F450, but my F250 does what i need it to do.

I bought so-called OEM filters from Amazon and they weren't even the same dimensions and looked different and I tossed them in the can and went down to ford, do not make this mistake!!

I unscrew cap on under hood filter with drain valve open and it drains housings out good, then I cycle key on with new filters before tightening under hood filter housing to purge air quicker

very good recommendation about where to fill the tank, im a technician too and give u a plus for it.

I'm not sure if the the experience I had is covered in the below comments, but my primary filter would not stop draining and was siphoning from the tank. I made sure the fuel tank cap was off for no pressurization, One other comment below mentioned loosening the secondary cap first (maybe this would have helped break the siphon if done soon enough), however I did find another RU-vidr who said if you have a full tank it may siphon like mine. I did have a full tank. In that case you just have to be prepared to change the filter with no delay and take a diesel bath.

Where you get your fuel makes no difference. Let us take Valero for instance. They are branded but if Murphy has it cheaper at the hub, they buy Murphy gas. Mom and pop stores do the same thing. Trust me when I tell you your fuel may come from one location one day at your favorite store and the next day from a totally different refinery.

20,000 miles. Yikes. If it works it works but that seems long. Maybe push for 10,000 but that’s it

We busted the fuel filter cap on top and auto parts kept giving us a filter cap that looks like oil filter cap🤦🏽‍♂️. Even Ford dealer. The one they gave us is small but they insist it is the right cap. The one the dealer gave us almost falls inside the fuel filter housing.

Thank you for this video! I have the exact same year and model truck so this was absolutely perfect...Thanks again

What did you do to your egr valve? Look canceled?

Appreciate all your videos on the 6.4!!

After the deletes about 10k miles back PS the truck loves it. If you don't have $ large don't over tune it. Racing in these trucks will cost you large. My tuner is either set to stock or haul when I'm carrying or pulling the trailor. the truck ran so well after the deletes I had to put an after-market fresh air kit in. The stock box was too restrictive and would set off the change air filter senceor. I went with the S&B fresh air kit. Much better no she can breathe 😊. PS I'm getting a little too much black smoke after being at a stop. Is there a setting in the tuner I could maybe lower?

Great video from fellow 08 f450 owner....keep posting!!

@taylersmith what is the fix for the white smoke you where talking about

Great video thanks a lot man 🤙🏼

Hi, I have been watching your videos, thanks for sharing. I have a question, I have a 2008 F550 6.4, I am thinking to do the EGR delete, I bough the straight 4 inches pipe and the EGR tube, my question is do I need to bug the ecm? Or just go and remove the components? I know there will be check engine light. But it will work?

Another great video Taylor.

Looks like Taylor Smith is saving 401 people $$$ by helping them become a better man doing diesel maintenance themselves.

Bro, thanks for a simple yet very informative video!

I bought a filter by diesel doctor that looks just like ford. All 3 filters for 40 dollars hope this helps some one save some money 💰 ford wanted 75 just for the fuel filter

do you still have your truck. u haven't put up a video in a long time. just wondering if you quit RU-viding

Only - Only use Motorcraft filters on these trucks, spend the extra money, or you may be sorry down the road.

Very helpful

Hi Taylor been meaning to ask you what your getting for fuel economy after doing the delete kit. I have a 2008 King Ranch F450 and with the soft delete done I am presently getting 16l/100km.

Has anyone done this and about 10 gal of diesel come out?

Did you happen to have part numbers of those filters?

Doing This today and when I open my yellow valve a lot of fluid is coming out what do I do? Wait till it stops?

Where can I find a vid on that old Corvette in the background?

Forgot to mention gravity flow of diesel from the tank. So what a mess.

did u said 36 mm soquet?

How does the air purge out ?

Do you still have 6.4L ?

You inspire me to make my own videos ! I got one too and mine looks mean af 💥

When you will upload elcamino video

Brooo O’reilly’s played 7 ads during this 10 minute video they are so annoying

Found it 🤙, thanks.

Have you ever added two stroke oil to your fuel to lube the injectors?

What socket is that?

Thank you for the help video your videos are very informative. One thing I wanted to add this was my first time doing the fuel filter change on my 64 I’ve got a F5 50. I didn’t park up hill so when I opened up that fuel water separator valve it just kept on porn so I put it all back together turn my truck around and it worked out great
