    Are the valve stems on the 4runner like the TPMS factory ones on our trucks?

    If they are, the brass fitting on the Powertank looks identical to the one I just tried on my modified ARB. It was a "CTA Tools 1930 Straight Lock-On Air Chuck"

    I had the same issue. When I built it, it worked on my wife's Nisan fine, rubber valve stems I think. I tried it on the truck this weekend and I was like, this POS is getting sent back!

    The problem is with where they placed the valve stem itself.

    Picture swiped from an image search. See how it is recessed into that stylized lug? That opening is really quite small and limits the size of chuck that can fit into it. I think I'm going to buy her an inflator and change the chuck out to a round knurled slip locking type so that we don't have to rely on what I keep in my tool bag.

    Thanks! I bought the open version, and I like it a lot!

    Coilhose Pneumatics CH15A Open Lock-On Chuck, 1/4-Inch FPT, pictured on the left.

    I returned the one on the right as I was not happy with it.

    The Coilhose one works great, it has two pieces of metal which grip the valve stem making a really solid connection. The clip on one on the right, like the original ARB, only had one, and didn't work as well as I initially thought.

    I like the Open chuck vs. the closed chuck, because I can use the open version to blow dust off and out of my truck after finishing a trail in the desert.

    Thanks @Sandman614 for suggesting the Coilhose variant. :thumbsup:

    Not a QD, it's an air chuck called Coilhose that looks like a QD.

    Here it is laid out:

    ARB tire inflator + 8mm OD Hose Barb 9.5mm 1/8BSP Brass Coupler + hose clamp + your longer air hose + barb to 1/4 MNPT + Coilhose air chuck.​

    Search back two pages in this thread for details, or build thread has it listed too.

    @ramonortiz55 tape is a safety feature, covers the stainless size 4 hose clamp that secures the hose to barb.

    Just ordered this after trying to decide which one to get. It was between the Superflow MV90 and the Air Armor M240.

    I went with the Air Armor M240. Found a discount code here It says it ended but it just now worked for me. Its 80 bucks off.

    Thought id share.

    Anyone tried a Vixen 200psi kit with a 3 gallon tank? It says air horns but shouldn't it work for tires to? And lockers with a regulator?

    What is the perk to mount here vs under the hood is it not noisy when filling the tank?

    I'd say it's cleaner but judging by that picture lol. With the dual compressor filling a tank shouldn't take long. Also there's a lot of insulation because of the seat I would think it wouldn't be a problem.

    I guess I view it differently. Being a cdl driver it's weird not having a belt driven compressor. Even weirder for it to be located at the rear of the truck.

    Keeping it clean and dry mainly. Also its incredibly hard to make a mount to fit it under the hood without relocating something. When I have it on to run the lockers it isn't too noisy because the seat back is blocking a lot and isn't running constantly. When I am filling tires it is loud but I also lean the back of the seat forward for more ventilation. Also I don't run a tank. Don't have a need big enough to spend the money for it

    Its inside the cab, behind my rear seat. The second place I would have put it is inside the bed side in the back.

    Questions:

    If one were to mount the ARB CMKTA12 On-Board Twin Air Compressor under the hood for a 2nd Gen taco (or even the single ARB CKMA12 Heavy Duty Air Compressor), would there be room to install a snorkel?


    Has anyone used the Slee Off-Road Tacoma Compressor Brackets for the 2005-15 Tacoma?

    Slee Off-Road–Tacoma Single Compressor Bracket (SOK-0002) – 2005-15 Tacoma
    <http://www.sleeoffroad.com/installation/2005-15_tacoma_compressor_bracket_v1.1.pdf>

    Slee Off-Road–Tacoma Twin Compressor Bracket (SOK-0001) – 2005-15 Tacoma
    <http://www.sleeoffroad.com/installation/2005-15_tacoma_twin_compressor_bracket_v1.1.pdf>

    If either of these were used, would it allow for a snorkel?

    It's difficult to tell from the photos on Slee Off-Road.

    My plan is to use the air compressor to inflate my tires after wheeling. Somewhere down the road, I may install a front locker...so, I'm thinking the twin would be the better option but space is the concern.

    Looking forward to your inputs.

    The Slee mount does not conflict with the OE airbox or intake tube

    For the OE airbox or intake tube, I understand. But what about a snorkel?

    I installed the single ARB CKMA12 Heavy Duty Air Compressor, mounted it with the Slee Off-Road–Tacoma Single Compressor Bracket (SOK-0002) in my hood.

    Now, I want to relocate the air source (quick connect/disconnect) to the rear of the taco. In order to do so, what are the exact parts I will need to buy at the hardware store (or online)?

    From the list of products discussed in this thread (at the bottom of the pages), would these apply for my situation?

    1. 12" or longer stainless steel braided leader hose without check valve -- to connect directly to the air compressor between the T-fitting and the pressure switch?
    2. MettleAir MTMF 3/8-N02-1PK Push to Connect Straight Bulkhead Female Fitting, 3/8" OD, 1/4" NPT? -- only 1, or will I need 2? Or one Female and one male?
    3. One of these air lines?
    a. 50' Roll of Power Products 3/8" OD Black Nylon Air Brake Tubing SAE J844,
    https://www.amazon.com/dp/B00CMTJQX4 - $43.55
    b. ATP Value-Tube LDPE Plastic Tubing, Black, 1/4" ID x 3/8 OD, 100 feet Length
    https://smile.amazon.com/dp/B000R87R4C - $15.44
    c. 1/4" OD x 50' SAE J844 Nylong Air Brake Tubing Suspension Horn Train Lowrider
    https://smile.amazon.com/dp/B00CLXGHQU - $20.49
    d. ARB 170301 Engine Air Intake Adapter (blue)
    https://smile.amazon.com/ARB-170301...rd_wg=ofrJm&psc=1&refRID=K5DZQVW6NF3A7Q2GPEFV
    4. Fittings:
    a. 90 degree brass pipe fitting street elbow, 1/4" NPT Male x 1/4" NPT Female -- two of these, one towards the air compressor, and the other at the rear end of the truck?
    5. Quick connect/disconnect

    Or can I just use the Viair 90007 Air Source Relocation Kit? Would it be compatible with the ARB fittings/hardware?

    Note: I also bought the ARB inflation accessory kit (orange air hose and parts) and the ARB blue inflator with gauge and braided hose. I'm trying to avoid having to open up my hood every time I need to inflate my tires using the air compressor. TIA.
