6.4 Powerstroke Fuel Filter Change! DIY Instructions

Here is a quick video on the process of changing the fuel filters on your 6.4 Powerstroke. I have changed the filters on this truck 3 times in the past 33,000 miles. I changed them once immediately upon purchasing it, and again 10,000 miles later. The 10,000 mile interval seemed a bit premature as the filters were still very clean. I decided to take this set to 20,000 miles, and they were definitely due for replacement, however they were not clogged or heavily restricted. Please Subscribe!

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

Are the Ford Motor Craft Fuel filters the same for the upper and lower? Or different part numbers?

[@jaredwatchman7333]

@@jerrylittle8922 they are the same, they come in one box with the o-rings.

I hate when people ramble on "How To" videos too. Taylor Smith is good about not rambling.

[@greggpaul8053]

Thanks for the positive input for the 6.4

[@mikebailey1241]

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.

[@jacobfitzgerald1251]

I will gladly change them all day on Friday though what his punishment should be is he should have to spend the rest of his days getting the air out of the system when customers mess it up that's the real pain on these 6.4 power strokes

[@roberthall7206]

Most definitely.. one should not be ready to throw a brick through their windshield and sell their truck after changing out what should be a couple simple fuel filters

[@strokin6fo330]

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

[@Lunchbox21984]

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.

[@TaylorSmithAutomotiveChannel]

Thanks for the tips! I appreciate the support!

[@ssbarjason]

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

[@TheDentalImplantCentreNE]

[@johnbolt665]

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

[@kevinoneill41]

Ya. What is it $150. For filters and 16.5X $6 liters oil and shop time. I have paid $200 for filters and $7.50 a Lt for oil + shop time.😱

[@kenhunt4356]

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 KZbinr 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.

[@johnbolt665]

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

[@jy7duality]

Great video thanks a lot man 🤙🏼

[@navyseabee7245]

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. ..

[@monicapadilladebarnett2940]

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

If you cycle the key to on without starting it for about 7 times, it will purge the air out of the system

did u said 36 mm soquet?

[@davidevans1378]

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.

[@majhail9516]

Do you still have 6.4L ?

[@johnbolt665]

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!!

[@christophermercier1760]

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

I think it's a 36 mm but check it.

If you can get one that is 3/8 Drive it's a little lighter than 1/2 inch.

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

[@JT-qf4it]

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.

[@olivierdlegault]

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

[@FTGrental]

Appreciate all your videos on the 6.4!!

[@codybranch6875]

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

[@vitatang904]

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.

[@kevinoneill41]

That doesn't sound good.

[@kevinoneill41]

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?

[@nicholasolafson9758]

Taylors got a great video on how to tune your 6.4 if you have the H&S minimax. At around 4:10 in that video he mentioned how to adjust low boost fueling. kzbin.info/www/bejne/aqSQZJ2wgpdknJo

[@mikedemaret9459]

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

[@boujeenative5868]

I found that out the hard way. Bought cheap duralast filters. Didn't have the tab or weep hole. I tried on and off for 4 days to get it to start. Went and purchased motorcraft. Changed them out, had it running within 15 minutes 🤦

[@curtismagas9343]

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.

[@TaylorSmithAutomotiveChannel]

Curtis Magas my onboard screen shows 14.9 mpg average and 17 mpg on the highway. Unfortunately it does not seem to be accurate because when I calculate it out by hand it never gets better than about 12.5-13 mpg in town and 15 highway. I have 4.88:1 rear gears so the mileage will never be too good.

[@MrMadaket78]

@@TaylorSmithAutomotiveChannel I too, have a 4:88 geared F-450 2008 model. Completely stock, I usually get about 12mpg at 60mph on the highway. Towing heavy fifth wheel, returns 9-10mpg. Good video on the fuel filter change out. Just want to add, I open that drain on the lower filter once a month and drain off about a pint of fuel into a clean mason jar. Give the jar a swirl and look for water bubbles, trash. Good way to keep water build up in the filter housing. Every fill up, I use Power Service Diesel Kleen, silver bottle in summer, white bottle in winter. Hopefully helps protect the hpfp. Original owner, been a great truck. Oh, and keep an eye out for corrosion on the bed supports, well known area for corrosion. Enjoy your posts

[@kevinoneill41]

I can say I increased the mileage by 5 miles per gallon. No more embarrassing regen. God that would stink. I do not believe that system could be better for the environment. A properly maintained tuned and at temp seems to run so clean. I working on introducing a little propane to the intake when at a stop and then off after taking off. I'm getting less black smoke but have lots of bugs. 😢

Or just go and remove the components? I know there will be check engine light. But it will work?

You will need to get a tuner, if you remove with out one the truck will go into limp mode if it will run at all.
