Follow the service schedule in your owners manual. I believe it recommends 30,000 miles between changes. It looks like a simple job, just youtube it. Pretty sure you just drain the bottom filter, while that is draining swap the filter out under the hood and then take the 4 or so screws out holding the filter in under the truck and slap a new filter in. Then you have to purge the air out of the fuel lines by turning the key to "on" not "run" for 30 seconds. Might have to do that 5-10 times. You can hear when it grabs the fuel.

I have done my own for the last 20+ years. Not difficult at all.

My new tremor is a 7.3l... So no more fuel filter changes for me...

But "two trucks ago" I had a 2007 3500 dually with Duramax/ Allison. I always changed my own fuel filters. Super easy... I even changed it once, in the parking lot of an Orielly's Auto Parts, in Texas, on a long road trip, with no tools.... Just my bare hands. That one sucked, but it still wasn't too bad.

YOU CAN DO IT, BROTHER!

Man this forum is awesome. I just had my first oil change, and they told me at 15k I need to change my fuel filter, and it was $200. So I started my research here. and am thankful.

Easy to check the fuelwater separator - if you are buying good diesel from a reputable station you won’t see any water. This was a check after 4000 miles no water.

The oil and filter change for the engine is by far THE EASIEST CHANGE I HAVE EVER DONE. I haven’t done the fuel filters yet, but I did change my water separator drain valve to the one from SPE, so I’m familiar with “dry sumping” is turning the truck on and off a few times to purge the air from the system. Here’s a video from YouTube that does a decent job of explaining how to refill the fuel/water separator.

@modified how do I do that? does that mean save it?

@Sludgemonkey44 - hey brother how do you like the SPE valve? Are you happy with how it drains? Do you recommend?

Ustank2 · Feb 10, 2021

My question is ...
Where does the air go? To the secondary filter? Or back to the fuel tank?
*************
Went to the dealer last week to get service bulletin stuff sorted out. Dropped into parts to get a couple drain plugs. Not in stock after ten minutes searching the back. Amazon may be your friend

Well so far I’m pleased with it. It is a slightly different design than the OEM one. It does not have the hole through the middle of it so the liquid drains out the side of the base instead of the middle so it has a bit of a dribble. I must say that when I was draining/removing the factory one, it drained through the middle hole for the most part, but it still dribbled out the side hole as well. I have a large enough catch container and I usually wear a pair of disposable gloves so that isn’t an issue for me, and honestly I don’t see much difference in the overall “drainage footprint” if you will, between the two. The other concern I saw that people had with it was about it being an avenue for outside cold to reach the fuel system with it being billet. I’ve had my truck outside in single digits so far and I’ve never experienced any issues. Haven’t seen negatives yet, but I’m not very concerned with it. So far I’m happy with the performance of it and I find it to be far more sturdy and reliable than the flimsy plastic OEM one. I managed to remove it without breaking it, so I have it in a pouch in the truck as a backup/help another one out someday part. Hope this helps. Let me know if you have any other questions. ???

Just make sure you keep all
Of your receipts and document when you did it for warranty

I just changed my fuel and air filters yesterday.
I went into the menu to reset the fuel filter maintenance.....and there isn't one??
Unless i just can't find it???????????
I reset my air filter one...but don't see the fuel filter one.
Weird...pretty sure there's been one since my 2012.
My 2015 definitely had one.
Has anyone else noticed that there's no fuel filter minder anymore?

I work at a Ford dealer and do this to my buddy's 6.7. Never crack both filters at same time. The system will get an air bubble and then you will have to spend 3 hrs trying to start the truck back up. do the bottom one re prime the system by keying on a few times then move to the top one and change it and do same priming procedure.

I did the bottom and then the top and didn't have any issues when I did mine at 15k miles only primed 5 times and was good to go
