    I did the diff breather mod today and figured I would post a quick "how to" for anyone who is considering doing it. It is a simple quick mod.

    Everything you need:
    1. Toyota Part numbers:90404-51026 Camary Union and 90930-03136 (Breather Union)
    2. Drill
    3. 3/8" drill bit
    4. Teflon tape
    5. 6' of 1/4" fuel line
    6. Screwdriver (flat head)
    7. 14mm and 10mm wrenches
    8. Hose clamps
    9. Zip-ties
    10. Wirecutters or razor knife
    11. Can of Skoal
    12. Ice cold beer (optional)

    WhatsNeeded_568bec01a16d1d18aa4e3c8e6e48be4c73af1cec.jpg

    Step 1: Take old breather out using 14mm wrench
    Removeoldbreather_6813d99fe42f1ae8cd6a39a180ea238f9ac429dd.jpg

    Step 2: Wrap new fitting with teflon tape.
    Wrapnewfitting_f74e4c17665554464e5654d9649456e3dd677c07.jpg

    Step 3: Install new fitting/union using a 10mm wrench.

    Step 4:Remove cubby to gain access to fuel filler (Pull up and out)
    Removecubby_21a85c251d4dda56d0474633caa871b5d2fad62e.jpg

    Step 5: Drill mounting location for new breather.

    Drill bit poking through:

    Step 6: Install new breather.

    A look from the inside.
    Insideveiwbreather_3884439d7eaf4479e7fa5608b1b9c771fcd68fa4.jpg

    Step 7: Attach the new fuel line and tighten clamp (using a little dish soap will aid in sliding the line on the new breather). I ran the line parallel with the filler neck and drown the frame rail not out the bed pocket as pictured)
    connectfuelline_b463432740b3c0e2768223d3b3040bbb666b5394.jpg

    Step 8: Run the 1/4" fuel line and use zip ties to secure it.

    Step 8: Install and tighten final clamp and be sure to leave enough line for axle movement.

    Step 9: Re-install bed pocket and you are done! Enjoy a cold beer.:D

    Thanks, I know this has been covered before, but I just wanted to post something that will instill confidence in those wanting to do this but were wary of their mechanical abilities. I know pics help a lot so I tried to document the whole thing the best I could.

    Hmm I had no idea about what this was until I watched the video... My question is... if I do only light offroading and never go into deep water since I am not 4x4 is it something that I should still maybe do? Keep in mind I live in So Cal and get hardly any rain as wel...

    (i may have answered my own question but want your opinion please)

    Just completed the install. I must say, the hardest (not that any of it was hard) part of the mod seemed to be getting the fuel line to go where i wanted it to (into the frame rail channel). Props to Neubs on the write up! The whole thing took me right at an hour, and turned out looking like it came like that from the factory.
