    In the process of being built..
    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.

    I don't see why it wouldn't allow for a snorkel I bought my ARB snorkel at Slee and talked to them about that mount and they said it would work great but you should call them just to confirm.

    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.

    Just about everything, but enough to do to keep me poor

    Nicely done indeed. This is the exact approach I'm taking on my 3.4 swapped 1st gen Runner. It looks like you are running 1/4" air line. If so, are you happy with the rate of flow, or if not is there any issue running 1/4" line on that compressor? Considering that an A/C compressor is typically pressurizing against a tiny expansion valve, I wouldn't think so, but lets see what y'all have to say about it.

    Everything is 3/8" line, minus the guage. Flow rate is great, with the heavier line as well helps with the heat coming from the compressor.

    interesting. I cant seem to find a 3/8 manifold like that, only 1/4", but it definitely was a great tip for this build. Where did you source all your parts? Amazon seems to have most things, but damn the brass fitting are expensive there...

    Ebay and Amazon is where I sourced 95% of the parts. A few were from my local Ace hardware.
    Certain parts I used from Viair for piece of mind.

    Alright... So I need some input fast... I'm currently working with Sierra Expeditions on installing an ARB Dual Air Compressor into the truck... I wanted to find room under the hood, but thats a no go. Then I wanted it behind the rear seat but was worried about the noise factor. So their solution was to put it underneath mounted to the frame rail... Initially I didn't think anything of it since the ARB system has an intake that can be relocated as necessary but now I am second guessing this route all together... Why? H20!!!

    They've already made a pretty bad ass mount/box to protect the compressor but I'm worried about any major water crossing (especially while running a locker - If I ever install one). The box/mount is located just in front of the rear crossmember and is definitely not water tight/proof but it is strong enough to resist minor impacts (plus there are other points on the truck that would hit rocks first). I'm just worried about water... Should I be worried about this location? Am I being overly cautious here? They want to finish up this project tomorrow and I am now questioning their chosen design. See pic...

    IMG_3803.jpg

    Anyone ever have issues with these underneath? Fast input would be hugely appreciated...

    I'm no expert, but I wouldn't want mine there. Deep water could fully submerge it, and it just doesn't sound like a good idea to me. Not sure how it much the compressor would like that. Imagine your compressor that low on the truck in a situation like this.:notsure:IMG_3551.jpg IMG_3552.jpg
    I know @Nate87 mounted his under his bed and @916TacoTruck has his mounted in his bedside where the storage cubby was and they worked fine. Maybe they can chime in.

    Is a small box somewhere in the bed out of the question?
    Good luck

    Yeah right!? I agree... I'm a bit surprised Sierra Expeditions suggested this spot... it just doesnt seem smart...

    Even under the bed it would be higher up and better than where it is now but still exposed in deep water...

    And yeah there is no way I'd consider loosing more bed space... so a small box is out of the question...

    Not an ARB, but I plan on mounting my Viair 444c on the side of the bed tub between the tub and the bedside. Going to make a L mount to spread the load a bit on the tub and will put a backing plate on the inside of the bed. Will use a similar setup to mount the 2 gallon tank.

    What's the reason you can't use the slee mount? And also I know you said you don't wanna lose bed space but mine is perfectly protected in a tool box with my aux battery:

    I'm pretty sure the slee mount doesnt work with my CAI... Plus I'm still a little unsure how the relocation of the PS fluid works.
