Can anyone tell me what Filter this is and what it is for?
I have one on each side. I followed the hose thats connected to it
and it goes behind the wheel well to underneath the truck. Lost it after
that >.> Previous owner did this and I have no way of contacting him.

Went to a few places and no one knows anything...

 

Looks like the diff breather mods.
Hoses should run to both of your diffs, this is for high water crossings so water does not enter the diffs when the stock breathers are submerged under water.

 

Thats my guess too.

 

Thank you

What do I replace them with? They both look like that and are prob. really old O.o sorry for the noobie ?'s hehe I appreciate the help

 

Why replace them? Are you having problems?

 

unless they are full of mud, i doubt that they will need replaced...
dont worry about it unless you want something that looks a bit more spiffy...

side note, thats a really cool hood, what make is it?

 

looks like basic, cheap fuel filters

 

They have a lil bit of water in them, thats why I wanted to replace them. Is it anything to worry bout? If not ill leave em alone..Thanks


Got the hood off another 4runner not quite sure of the make

 

water is most likely condensation. pinch off the black hose below the filter, undo the clamp, r&r the filter (remove water), tighten clamp and unpinch the black hose.

reward yourself with a beverage of your choice, job well done!
