    Today I relocated the rear differential breather. These parts were courtesy of @Unchained 5150 . Rick, you will always be a part of my 4runner build buddy.

    The parts needed were:

    Toyota parts:

    Union part: 90404-51319

    Breather: 90930-03136

    One hose clamp

    Teflon tape

    about 6 feet of transmission hose. I went to autozone and asked them to provide some hose that fit the Toyota breather fittings. Took the fittings with me so they could give me their best fitting hose.

    Here are the parts pictured:

    Made sure to Teflon the threads on the union part. I fitted the parts into the hose to stretch it out and allow ease of installation once I was under the 4runner.

    On the driver's side rear wheel well, I located the fuel filler neck dust cover. I removed the lower clip that holds the fuel filler neck dust cover:

    Next I popped open the fuel gas door.
    This allowed me to grab a knife and cut a small hole small enough in the rubber surround to hold the breather fitting but large enough to allow me to fish the hose thru.

    I reached behind the fuel filler neck dust cover and pulled the hose thru

    The hole I made in the rubber surround of the fueling port is tight enough to hold the hose in. I didn't clamp this end since the hose was a very tight fit. I had to dab the fitting with some light oil to get it in the hose.

    I then fished the hose to follow the fuel lines and what not..

    I then located the existing breather:

    Removed it and installed the new union part. Make sure to Teflon!

    I went ahead and attached the hose and clamped this end.

    I allowed enough slack to make sure there is enough hose to reach during articulation by matching the length of my extended brake lines.

    Very nice job @ramonortiz55!! How much did the parts set you back? And does @Unchained 5150 sell this as a kit? Or where did you get your parts?? The reason Im asking....I've been looking at ARB's differential breather kit. It's really nice, but exspensive. Your set up is nice and clean...just like I like...and if I can save some money also....well...win, win!!
