That's true I had no issues with the ARB fittings on the diff housing. Thanks for the other info!

Yea I was going to just use the arb kit parts. Good to know before hand and start taking it all apart and start second guessing myself self. As for the tubing from the arb kit, one member said it's only 8m of tubing. Which if you leave extra on each end for future lift, then there wouldn't be enough.

again, i'm lifted and had plenty tubing for 2 separate runs including ample slack allowing for axle travel. keep in mind that "only 8m of tubing" is actually 26+ feet in 'Murican.
YMMV, but this is my experience.

ARB diff breather lines
The ARB tubing is thin-walled stuff. If it fails down the road your fix is worthless and the Diff' is open to the elements. I read in one of these threads that someone replaced it with 1/4" fuel line tube. That's a good option. Look for the right threaded brass fittings for fuel lines to replace the ARB fittings, if needed. I saw them at my local auto supply, Pep Boys.

I didn't know you were lifted. I guess we'll see when I decide to get the kit and install. Thanks!
At that point there wouldn't be no need of the arb kit. I understand the tubing is small but I do plan on wrapping mine in braided loom for added protection and it gives me the ability to put a diff color on so I'm not mixing tubes.

don't really agree here. the tubing is actually quite stout. and fragility is not a common complaint re: ARB products. also keep in mind the ARB diff breather kit exists to serve ARB lockers, and the air filters are the same design used on ARB's compressors.
seriously. gotta keep in mind this is a precautionary modification. spending the $ for the ARB kit, throwing half away, and DIYing the rest is treading well into "overthinking it" territory. it's like practicing abstinence but wearing a condom too, just in case—you can never be too careful. (green font implicit)
if you're going to use fuel line, just DIY the whole thing with a fuel filter or similar at its terminus and save yourself a few bucks on the ARB kit.
I agree. I'm still new to the 4runner world, let alone doing these specific mods. My Tacoma was a 2wd prerunner so no lockers or anything. But in that I did do mods to it, so I think if a company designs a kit specifically for the mod, it's safe to say we are good to go with what's supplied.

Do you think the ARB tubing will withstand northeast temp swings from -30 to +100? Also what size connectoer will fit from e-locker tube to said tubing?
I bought a variety pack of connectors from the local auto parts store. There were connectors which fit but I don't remember the size. 1/8-1/4? 1 set of connectors was enough to install the ARB kit while making a T connection for the rear diff and locker to feed into one line. I imagine ARB designed it to sustain those temps since the outback gets pretty toasty but -30 is pretty frigid. I don't think the line would have an issue being that cold. If there was fluid which froze and expanded then yes it would probably crack but if that's the case then you have bigger issues than the line breaking.

Thanks. I broke down and ordered the ARB kit. I've had the truck three months and have already gone through several water holes at least a foot deep so I'd better get this done. I thought about a tee connection between the e-tube and diff line to one line up front but some folks on other threads had concerns about diff oil vapors getting into the e-locker and mucking it up. I'm thinking I may run two lines just to be safe.

Just as an FYI, the amount of tubing you will get will be close in terms of making two runs up to the engine bay (I don't have a rear locker so I only had to make one run) as it only comes with 8m of tubing. If you are relocating to the gas cap or somewhere else on the rear of the vehicle it's no issue. I contacted ARB before about getting extra line if you need it. The info is on this thread post #70. Good luck with the install!

ARB tube resiliency
I think someone who has some extra ARB tubing could test this. Throw a piece in the freezer for a day and then bring it out into a warm place. Then throw it back into the freezer for another day. Repeat 30 times to simulate repeated temp' swings during winter.
Lots of good points here about how ARB made this tube for the intended purpose under normal use. I also like the idea of using 1/4" tube and a fuel filter in the engine compartment to make a DIY kit. Just add a tube turned down at the open end to keep water and dust out. Or bring the tube from the rear up and over the filter, with the open end pointed down.

After running the line from the engie bay and leaving an extra loop for suspension travel above the rear diff, I had 12.6 feet of tube left. I ran it to the e-locker tube and still had about 8" of tube left over. Just enough. Made me feel a little better about the $70 for the kit. Smooth easy install. Thanks for the tutorial.

That's great to know and hear. Glad it helped and everything worked out!

So just to clarify here, you ran 2 separate lines, one from e-locker, and one from diff, to the front to where the ARB unit was installed? And you just used everything in the kit? How exactly did you fm connect the e locker tube to ARB tube?
Cool thanks. Haven't gotten a chance to get under and look at it yet. Wasn't sure if you could get to where the e-locker valve is it or if you just had to cut the line running out and attach it to new one. Appreciate it.
The arb kit comes with a replacement fitting and the tube in the kit locks on the the fitting due to the style fitting it is.
