Motorcraft FD-4616 Fuel Filter

I always stick with OEM parts when it comes to maintaining my truck, and the Motorcraft FD-4616 fuel filter is a perfect example of why. This filter fits my 6.0 Powerstroke perfectly and performs exactly as expected. Installation was straightforward, and everything lined up just right — no leaks, no hassle. What I like most is the peace of mind knowing I’m using a filter designed specifically for my engine. It keeps fuel flow smooth and clean, which is essential for these high-pressure systems. I replace mine every 15K miles, and this filter has never let me down. If you own a Ford diesel, don’t mess around with off-brand filters. Spend the extra few bucks and get the real deal — your engine will thank you.

Use a short Wall 35-36MM socket for bottom filter, 6 MM Allen wrench for water separator, and 24MM or 1/2" Weather Drive. loosen fuel cap to relieve any pressure, Put oil pan under lower filter to catch water and fuel. Drain water separator first tighten back up snug, then remove frame filter (shallow socket works best). Put the new filter in with air bleeder hole to the top facing more to the frame then slightly twist it clockwise to lock it in. Put new oring on the cap then screw it on the filter and tighten to 18.5 ft lbs. Secondary (Small filter) use 1/2" drive wratchet, 24mm, or 15/16" socket to remove. Replace oring, filter, then reinstall to 10.3 ft lbs or 14NM. Turn key on for 30 seconds 4-6 times to purge air and pump fuel. Fire it up! I replace mine @10k intervals and primary comes out still useable. I cut the water separator from the filter to inspect it. The new one did have some access glue but not bad. Primary is 10 microns and 2ndary is 4 microns. The part numbers printed on the filters has changed since I replaced them 1.5yrs ago. They are OEM Racor/mc filters. Pics attached. Love my 6.0!

This is an OEM Motorcraft part at a fraction of the cost of the dealership! Don't get off brands of Ford filters; there are just too many problems. Get these originals at a little more cost than the knock offs, but half the cost of the dealership and you get the best of both worlds. Changing them is easy. However, 19 nM is not the same as 19 da. nM... The plastic cap on top of the motor housing says tighten to 19nm, and so I used my 1/2" torque wrench and did rotated it to 19 and tightened it down... Well, the 1/2" wrench is in DA NM (deca newton meters....) = x 10.... So what should have been tightened to 14 ft. lbs of torque (which is correct, btw) was tightened to 140 ft. lbs.... Well, it's on, but I don't think it's coming off... LOL The filter on the rail uses the same 36mm wrench that your oil filter cap uses. Some people have said 35mm fits as well; couldn't say. I didn't have either and had to wing it with something "close enough". It would make sense that they used the same wrench as the oil filter housing for ease of tools. Anyway, plenty of great videos on YouTube on how to change these out, and I feel stupid for paying the dealership for 5 years to do it for me at 4-5x the cost of these parts.

I ordered these and they were 100% motocraft filters. They were both wrapped in shrink plastic inside the box with both orings. Im very happy and I would order them again Thank you

These are a standard maintenance item, they can get expensive if you can find them in stock locally, Amazon allows me to get a great product at a great price and delivered to my door.

The real deal everything fit as it should

These filters fit and don't leak Diesel. What else can you ask for, except a lower price. For what they are, they are pretty expensive considering there are no moving parts nor electronics. They literally just sit there and filter... Make sure you watch the install vids that are out there 'cuz if you do this wrong, you can break the plastic housings without even trying.

This fit my 2003 Ford F-250 with 6.0L Diesel. The secondary filter was leaking around the cover. This kit came with new o-rings and sealed it right up. It was time for new filters anyway. I inherited the truck and don't know if they were ever changed. The secondary filter is right on top of the engine and really easy to get to. All you need to remove the filter cover is a 1/2" ratchet wrench with extension. The cover has a 1/2" square recess in the cover for this purpose. The primary filter is in the drivers side frame rail. It lines up just rearward of the A-Pillar. You'll need a 36mm socket to remove the cover for this filter. It's relatively easy to get to also. 5-Stars for Ford Quality. I've learned over the years most cheap aftermarket parts aren't worth the headache.

Just what I needed for my F250 diesel truck oil change. The 2 fuel filters were a perfect, authentic Ford Motorcraft product not a knockoff. The diesel oil filter by Wix was just what I expected. Went together as they should.

MUY BUEN PRODUCTO ES ORIGINAL

So as per all the forums and YouTube, stick with OEM. This product seems like the legit thing. No issues related to the fuel since installing and I am due to redo it shortly after about 2 oil changes.

OEM , good product and better price then getting it from the dealership
