My buddy finally shared a couple pics he took of me.

Drew this up quickly. Here's my initial thoughts...it will help clarify things. ...I hope. As I was uploading to photobucket, I was thinking and I might switch it to supply the grounds to the MV50, rather than the 12V. I need to research the Bosch relays current rating and what the MV50 current rating.

I don't think so. I would prefer that the switch cuts off the pump. However a pressure regulator might be a nice addition as a safety feature in case the electrical switch fails....cheap insurance. Switch description states that it opens at 10psi and closes at 32 psi. I will need a relay to switch the 12V on to the pump when the circuit is open and shut it off when it reaches 32. This is strictly for auto-filling 2 tires at a time. I will add a switch to bypass this functionality for when I'm in need to fill the tank, providing 12V to the cutoff switch that will cutoff the pump at the tank's pressure.

I won't spend money on form, if the function can be had at a better price. ...frugality is one of the reasons I do all the work myself if I can do it.

Using a relay, you can reverse that operation to function in the reverse. I will explain when I set up my test. At 10psi, there will be 12VDC to the compressor. At 32psi, the power will be removed. This switch would be for the tire fill function. The switch for the tank will be matched to the rating of the tank I get. Thanks for saving me $20! I'll look in to that alternator. Thanks! *Quick disconnect (3) and air chuck added to shopping list* I don't think I'll need a regulator...I don't plan on limiting the air flow. Is there another need for a regulator? How do you drain the condensation from your sliders?

For $500. Just mount an LED bar. 0_0

Well...maybe this evening. I ship everything to my bud's house so the package doesn't get stolen. I'm swinging by tonight on my way home. In my search, I've run across this. 10-32 psi low pressure switch. Opens at 10psi and closes at 32 psi. If I'm aired down to 15psi, then this is what I need.. http://www.zorotools.com/g/Pressure%20Switches/00018675/ I will have to use a relay for the power. It will probably take some bench testing since I may be the only one trying this (no hits on google)....and the 1/4" fitting might change the pressure. In theory it shouldn't...but...best to check. Any HVAC techs here? If I figure correctly, this switch is used to protect the motor if pressure falls below 10psi. In my case, it will do the opposite, turning it on at (or above) 10psi and cutting it off at 32psi, so a handy dandy relay may be needed. I have plenty of them lying around. 8) After more thought, I'm going to add the removeable tank. I'm going to keep an eye out on Craigslist for a cheap air compressor...3 gallons seems common for oba systems. Just need to do some shopping at Home Depot and pick up some brass fittings.

Air filter, MV50, and tire cover ordered over the weekend. Should have everything by this evening.

Just to be clear...I don't write policies. Navy Veteran and now contractor. The better I am at my job, the easier it becomes....being slightly neurotic helps also. I can get OCD at times. Sometimes it's a blessing....other times, it's a curse. I say the same thing about the inability to wear beer goggles.

To clarify, the intake of the pump wouldn't be to the engine's intake. It would be routed to the air cleaner/filter box...well before smog equipment and wouldn't affect vacuum. To scavenge filtered air. I guess some of the complaints/failures with the MV50 has been blamed on dirt entering the intake of the pump. I haven't decided 100% on doing it yet...it's still on the table and can always be added. I sometimes go to Superstition and some areas can be very silty. (for those that don't know...essentially powdered sand). Some have mentioned years of use with no problems, but I don't know where they venture. It's time for a new air filter, so I am also upgrading to a K&N to help with filtering and I hate buying filters. I've ran K&N or some version of a reusable filter on every vehicle/motorcycle/offroad toy I've ever owned. 8) I did see a guy that made that 4 way system, but I was thinking of just a 2-way. Maybe if I get 2 pumps or if I add a removeable tank and have more pressure, I will go 4-way. They do make adjustable air pressure, electrical switches. It will get it in the ballpark, then I can discriminate wheel by wheel. No...no 10 second fillups. A few minutes won't kill me. But being in government service for so long, I always go overkill and as efficient as possible. Better to overdo and be able to backoff a bit than to underdo and have to redo. That's why I plan to plumb for the tank and add it later. My buddy made a good point...if you don't have a tank and pop a bead, you won't have the rush of air needed to get it back on the rim. Just things to think about.

I was going to ask about this. Quest? Is that a brand? The reason to plumb to the intake is to prevent sand, dust, etc. from entering the engine. I've done alot of baja bug driving, so I know dust and sand get everywhere. It's an idea, I've thought of incorporating. I also read yesterday that others only run the stock filter with no issues. I may hold off on that one...if I can remember to do filter maintenance. I'm a busy single dad. See this thread: http://www.jeepforum.com/forum/f27/my-costco-q-maxx-mv50-compressor-build-700416/ The reason for the plumbing is to plan for the tank addition. That's for sure getting done. Stioc: Does the airline that came with it reach all 4 tires??? I want a pressure switch, so it's a "set it and forget it" operation. I'm on my own to dismantle my tent and pack up. This way I don't have to check the tire every couple of minutes or worry about overinflating because my daughter has to go pee or my son falls and starts crying (both of these happened while I was packing up last time. I'm also considering carrying a spare, since I've learned that my light duty ones won't fill up a 33x12.5 tire....and they're only $60.

Lots to think about. Since I don't have the locker, I will plan on plumbing a t-valve to accomodate it's future use. Is that brass plumbing? I need a compressor first and foremost. So..... Here's my thoughts...do this in steps. 1) Buy the MV50 compressor...best price I see right now is Amazon, since I also get free shipping. 8) 2) Mount compressor with intake to air box. 3) Plumb compressor with 35 psi switch, T-connection, air connection, and pressure gauge. 4) Hose long enough to reach all 4 tires from engine bay. I'm either going to do: a) removeable tank mounted to roof rack permanent tank, mounted under rear c) Have rock sliders made that hold air. Thoughts, comments, ideas? I found a very thorough review on the MV50 here: http://www.toyota-4runner.org/3rd-gen-t4rs/131953-bfads-superflow-mv-50-air-compressor-build.html

Tack weld them?

Pretty simple. Star screw on the tail side secures the rack retainers on each side...those slide off. Then unscrew the bars and slide them off one at a time, in order.

Not I... For $200 less I can get a VIAIR system with tank. Thanks for sharing your info and experience! Can you post pics of your sliders? I found your Shutterfly link, but didn't see pics. Also, what type regulator are you using to limit the air to 35psi? You have the air solenoid on a switch? I've read that you need a compressor with auto shutoff in order to activate air lockers.

What model? True. After research, I don't know why they show air tools next to them. The only way to run air tools is to spend the dough for a custom belt running a pump. Some vehicles have AC delete kits. Probably not much for the R50 since there isn't a whole lot of aftermarket support to begin with...

Intake of the compressor from the air box. Sorry if I wasn't clear. ...from my cell...using Tapatalk

I've thought about putting one on the front bumper. How do y'all keep it secured from theft? My truck is parked in the condo's lot.

So, my plan is possibly/hopefully have an air-locker setup. The MV50 doesn't have an automatic shutoff, which is required for the air locker. However the inexpensive cost may be my swaying factor for the time being... I may just go with a simple mount for now and add later. Did you order your MV50 from Amazon?

I looked at his thread (one of the ones where the links are dead). If you find it, he links to his Shutterfly site....there's a couple of pics but not much. I don't think I'd be comfortable doing it that way. I would have a pucker factor every time the sliders hit a rock. I've been doing some online searching and I like the idea of running the intake of the compressor to the airbox. It's a pretty simplistic idea that I didn't think of. I looked at the MV50 and MV90. However for a few dollars invested, I can run an air tool. I live in a condo and anytime I want to run my compressor I have to run a heavy duty extension cord to the garage. (PITA.) Even for a quick air-up or air grinder action. I didn't think about under the truck...I'm going to crawl under there and look...maybe there's room to mount the tank and protect it somehow. Do the later models have the storage compartment also? I also had thoughts of cutting that out to mount the tank there, but also have access to the drain. A couple of useful threads that I found searching the forums. Interesting idea. Uses rear bumper, but no pics. http://www.nissanpathfinders.net/forum/topic/24483-onboard-air-revisited/?hl=%2Bonboard+%2Bair XPLORx4's thread. Again no pics, but the link in his profile sends you to his Shutterfly account...can spend a few minutes there with visual trip reports. Also where I learned about the MV50. http://www.nissanpathfinders.net/forum/topic/13995-on-board-air/?hl=%2Bonboard+%2Bair&do=findComment&comment=230243

Since I was ordering the kit and it was a matter of KISS, I ordered the lines from Krypton Fabs as well. FYI: From his site. http://www.krfabs.com/product_detail.php?productID=2 Braided stainless steel extended brake lines (front) - Add: $80 Braided stainless steel extended brake line (rear) - Add: $55

So, not that my dual battery and power distribution projects are 99.99% completed, I'm researching onboard air options. My HF air compressor did not do the job on the last trip and rather than leech off others, I need to be self-sustaining for trips. The HF compressor was good when I had 31x9.5 tires, but with the 33x12.5 it doesn't work. It got so hot it shutoff after only putting 7 or 8 psi in ONE tire. I thought it fried, but I guess it has a temp shutoff feature. Right now I am considering the VIAIR Ultra Duty system. I figure for $100 more than the Heavy Duty (up to 35" tires) it's worth the benefits of being able to use air tools and it's "for all tires" so I can also fill up others in need. Reference link: http://www.viaircorp.com/OffRoad/oba.html I see others with onboard air, but can't see many pics (outdated) of where they mounted the tanks and compressors. I also have only seen one in the R50 section. 01silverpathy, IIRC? I am thinking of mounting the tank in the storage compartment...if it would fit??? I would need some way to extend the drain, so I can drain it in between trips and access it when needed. I may have to remake my rear storage or modify it somehow. The pump would either go under the hood or also in the storage compartment. Throwing ideas out there... If anyone has pics of how they set up theirs, I would appreciate it. I considered the spare tire carrier, but I plan to put the gas cans there. I considered the roof rack, but would be concerned about theft. The other option is in the storage system that I built....making one section dedicated to the tank/pump/etc.

I thought about that trip but my work Christmas party is Saturday. ...and I can't do Mondays. My next trip probably won't be til the end of the month. ...from my cell...using Tapatalk
