Is there a special wrench for this OR just use an open-end or socket that fits??

I thought reading somewhere that the Fuel Filter housing underneath the drivers side of truck was very tight access and a special wrench was needed in order to replace that filter??

THANKS!

The oil filter and the fuel filter on the frame rail are a 36mm. I don't remember what size the secondary fuel filter is though. I use a 36mm socket, but I suppose you could use a wrench

The oil filter and primary fuel filter both use a 36mm socket. I got mine on
e-bay for like $9.00 shipped.

You are going to want to get a socket to do this as you need to torque them to a particular setting and an open ended wrech (even if you has that size:crazy:) would not work.

Torque settings
Primary Fuel filter and Oil Filter 19 ft lb


Hope this helps.

The other one is a 22 or 24 mm socket. Cant remember which for sure.

Wrench works fine as well. I just use the socket and a 1 foot extension for the fuel filter

You can also use a 1/2 drive extension in the square opening of the secondary fuel filter. Thats what i use. :wink[3]:

Do not and I repeat do not use the square end to pull the upper fuel filter off it will crack and cause a lot of grief. Not a if but a when. Upper fuel filter is a 24mm. Lower fuel filter is 36mm. I had the socket because coincidentally it is the same size as the front nut on a 88-98 chevy front cv axle. Autozone sells the socket cheap and will or would even rent that socket. You can go about it a few ways on a 4x4 truck. Either get some long extentions and get past the tcase skid or use a ujoint and put it on the socket then a long ext or a very small ext like 1"-2" and then just work between the drive shaft and the frame. Either way kind of a pita. I did them yester day with the ujoint. Took me about 30mins.

I agree...I went to change my filters for the first time (dealer did my fuel filters 1st time I had them done) Did the bottom (primary), went to do the top and it was cracked. Did not want to chance making it worse as I was leaving the next day on a long drive, got a new one.

I have the Snap-on flip socket for mine and it's great. Like said above be sure to use the correct sockets or you'll crack the filter casing. Steve

By the way, that $47.95 is for both filters and o rings. Everything you need. The new part # is FD-4614. :)

Ryan. the Snap-on 2 sided socket for the 6.0 is around $30.00. The oil capacity with a Motorcraft filter is 15.0 quarts. There is a abundance of opinions on oils just read the forums and make your choice based on your budget and what make you fell good. Synthetic vs Dino oils. Good Luck....
