Wrench for Oil and FuelFilter housings

[Pathfinder22]

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) 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

Secondary Filter housing uses a 15/16 socket

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

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.
