I'm betting the 400 (non-sealed) and i'm installing it inside. Either in the "trunk" or under the driver seat (computer is under the passenger). If your getting a viair and mounting it outside, like RTon said, get a SEALED compressor (the 450 is sealed).

I don't mind the bump stop, i'm on 15"s right now so i'm sure it'll be slammed regardless of the stop, and the stock rear struts will prolly bottom out first (i'm gonna get either the monroe's or the nice koni's down the road).

RTon again thanks for the links and info. Now i know what size fuse to get for the viair ^_^. I would get a 30 right? Or like 35 just to be safe? Also thanks for the links for the T's, i will probably purchase those. Like i said i plan on ordering the parts (not fittings) first and laying it all out on the ground and coming up with the best possible plan for what i want to do. I'll prolly post pics or make a diagram and post it up because i'm sure i'll ask questions and look for opinions.

What guage do you suggest, i can't find a gauge that lists that it is 1/8".

Also, are NPTF fittings the ones that you push the line in and it locks around them? What did you recommend on those again? i can't remember >_<;

Like for instance, between a rear bag and the T fitting up there, would i do this:

1/2" OD x 3/8" NPTF Male Elbow http://suicidedoors.com/1-2_OD_x_3-8...Male_Elbow.php
3/8" DOT airline
3/8" OD x 3/8" NPTF Male Connector http://suicidedoors.com/3-8_OD_x_3-8..._Connector.php

The line would just be cut straight and pushed into both connectors right? Thanks

 

OK... I'll try and address these in the order you posted...

You can run an inline fuse for the compressor. I would typically run one that is a few more amps than what it pulls. I have seen compressors pull more amps and start blowing fuses. If you install an inline fuse, you'll know really quickly if it isn't enough amps. Your other option (better, in my opinion) is to run a relay and a breaker. You will really want to run a relay regardless. Suicide Doors and Bagginit.com both have wiring diagrams that show how to wire up the relay. You can replace the inline fuse with an inline breaker. They act just like a fuse, but can be reset rather than having to put in a new fuse.

Here is one website that carries them.. I am not recommending them, but at least you can see what they cost, and what they look like. They are called "High Amperage Weatherproof Circuit Breakers" on that site. http://www.wiringproducts.com/?target=dept_11.html I usually the "push-to-trip" type.

As far as the fittings go, it is very good to diagram your system. Another option, as I mentioned in another thread, is to buy a fitting kit from http://www.innovativeairsuspension.com. Larry has several different kits. And each one is geared toward a specific installation. Right down to where you are planning to mount your valves. The kits for a 3/8" valve / 3/8" line kit list for under $150. This is a pretty good buy for the time and effort it takes out of your planning.

Now to the gauges. I am not sure what size each of the different brands accept. But the good news is that regardless of which gauge you run, you can make it work with the drilled "T" with the right fittings. I would just confirm when you order that you will receive the correct size airline for the gauge you are ordering.

The fitting you show in the first link are plastic PTC (Push-To-Connect) fittings. NPT stands for National Pipe Thread. The "F" at the end is the designation for female. It looks like Jason is using the female plastic PTC elbow fitting and screwing a brass hex nipple into them to make them male. The second link is a brass PTC fitting. The PTC fittings work just as you described.

A lot of people have been using PTC fittings for years and absolutely love them. I, personally, am not a fan. And if I were to run them, I would only run the brass version, never the plastic. You will notice on the Innovative site that his fitting kits include only brass fittings. I am not sure of anyone online that sells a complete compression fitting kit. That you would likely have to piece together on your own. You could do that locally or possibly at http://www.hoseandfittings.com And regardless of what type of fitting system you use, you want clean, straight, square cuts.

 

The newer SMC plastic PTC are really nice, they have a higher crush rating then brass too...heard nothing but good things. As long as your airline is nice and square at the cut you should have zero problems with the plastic SMC PTC's from SD.com

 

Thanks for the tips. I'm not sure which to go with. I will probably go with the fittings from suicide because if i don't like them i can always step up. The fittings themselves are not that expensive so it's not a big deal to me.

I have a few more questions tho... for the Viair 400c, it's leader line is 1/2" right? So i would want to get a 1/2" water separator? http://suicidedoors.com/SMC_Water_Trap_1-2.php

About the breaker/relay thing. I don't rally understand too much about it. I'd love it if you could point me to a specifi product i can get. The breakers on the site you posted are minimum of 50 amps, isn't that too high? Should i get something like this:

http://www.innovativeairsuspension.c...on=show_detail

Now for some more questions

This pressure switch on Innovative's site is a 110/145 that "maintains viair's waranty". The only thing is it's 1/4" NPT...

http://www.innovativeairsuspension.c...on=show_detail

Should i just get a 1/2"->1/4" reducing bushing and put the press. switch on it's on port on the tank (being that i have plenty of ports)?

http://suicidedoors.com/1-2_x_1-4_Reducing_Bushing.php

Or should i get a T in between the water separator and tank? I'm guessing i should just run it to it's on port being that i'll use 1 less T fitting. Thanks for the link to those drilled 1/8" T's though, i'll definitely get them

Would you recommend me getting this? Air Line Cutter

http://www.innovativeairsuspension.c...on=show_detail

?

What do you think about this gauge?

http://www.innovativeairsuspension.c...on=show_detail

Is it 1/8"? I know i won't need it to go up to 200, but i think it looks more sleek then the other 25$ gauge on Innovative's site.

I appreciate all the help, i'm getting excite about ordering the stuff. Hopefully i'll have the bags, brackets, compressor, valves, tank, gauge, water trap, airline, pressure switch, relay or breaker soon! Then i'll be able to visually see in my hands what fittings i'll need, also i can size up the parts underneath the rear of the xB and see where i'm gonna mount it all ^_^.

 

gonna skip around an try and help ya...

Viair Warranty
The Pressure swith must be a Viair pressure switch and be on the same receipt as the compressor.

Pressure Switch mounting
If you have the extra ports use the reducer bushing and mount the PS to its own port.

Airline Cutter
The cuts need to be as square as possible, this is more of a convenience then a nessesity.

Gauge
I am pretty sure the KP guage is an 1/8 inch fitting, so are the viair gauges

 

Thanks, even though that pressure switch says it maintains the warranty it doesn't? I can't find viair pressure switchs on any sites online

Thanks for the other info.

 

I am not sure about what size the leader line is to the Viair. For some reason I was thinking it was 1/4" NPT not 1/2" NPT. But I could be wrong. Your best bet is to call whoever you plan to buy from. Viair does sale braided stainless leader hoses on their site separately. They are 1/4" NPT and I assume they would be the same ones they use on their compressors.

That relay would be fine. I know Suicide Doors has them on their site as well. As far as the breaker goes, check with a local stereo shop. Most of them would have them. Just look for a 40 amp weatherproof switchable breaker. They work just like a house breaker, and similar to a fuse. Except that instead of burning out a fuse and having to replace it, all you have to do is reset the breaker. Much more convenient than if you blew a fuse out in the middle of no where without a spare.

That's how I would typically do it. You'll get a more accurate pressure reading that way.

Agreed. Directly off of your tank is the best way if it is an option.



An airline cutter does make it pretty easy to cut the airline, but it isn't absolutely necessary. I have done plenty of installs just using a utility knife. It takes some practice to get consistent good cuts, but it can be done.

Of all of the common gauges on the market I have always preferred the look of the KP gauges. I'm not sure what size it is. A call to any of the shops that sell it, or even KP themselves should be able to answer that question for you.

No problem at all. I like helping people out with air suspensions. Especially people new to the scene.

 

The Viair pressure switch is the same exact pressure switch everyone sells. Just buy the compressor and the pressure switch at the same time. Make sure you buy the right rating 110/145 and don't even consider and adjustable.

And remember Viair's warranty is only one year. The likelihood of even an abused compressor burning up before that isn't very high.

 

lol yea, i'm not concerned about the waranty as much as just having a pressure switch that will work. Thanks for all the help man!

Does the pressure switch bassically fill an empty tank up to 145, and once it falls down to 110 or below fills it back up to 145? LIke if i install everything in the xB, and turn on the car (so the compressor can run from the ACC line), will it fill the tank up to 145? I bet it will have to turn off before it can right? Let me know how that works man, thanks.

 

I've been doing some diagramin' and i'm a little stuck on the compressor to the tank...

So the viair is 1/4" and comes with a 1/4" leader hose that's male and has an in-line check valve. Is it male on both ends? So it screws into the compressor and then would screw into the tank (or water separator)? So if i was to get this water separator:

http://suicidedoors.com/SMC_Water_Trap_3-8.php

So i have the compressor with a line from it that has male 1/4" on the end. That would screw into a reducing bushing that is into the water separator (3/8" to 1/4"). Then on the other side of the water separator i would get a 3/8" male to 3/8" PTC then run 3/8" DOT air line to a 1/2" male to 3/8" PTC at the tank. Is this a good way to do this? Is there a better way? Let me know man thanks.

Also, would the weatherproof 40amp circuit breaker be in between the battery and the 12v line to the compressor? If i was to put a switch in the middle should i put it before or after the circuit breaker? Thanks

 

Why not do it this way (compressor --> tank):

Leader Hose : 3/8-1/4 Reducer : Watertrap: 3/8 nipple: 1/2-3/8 reducer: tank

Just mount the water trap right to the tank....as for the breaker it goes on the 12v to the comp, I wouldnt put a switch on that line but on the 12v to the pressure switch (no signal from PS and the compressor wont turn on)

 

Thanks man! I didn't know if i could do that or not. Should i just use regular teflon tape on all the fittings or is there some special thing i should use instead?

Also, what gauge wire should i run for the pressure switch and the comp?

 

Found out another good thing, this water separator from FBI is 1/4":

http://fbimini.com/product.asp?idno=4024

So i can eliminate the reducing bushings.

I will attempt to make a Microsoft Paint interpretation of all this some time this week. What you think so far?

 

your going to need a relay for the compressor. but seems like you have figured it all out pretty good... lets see your fitting diagram....

 

why dont you just order the smc valves from suicide doors? or is there free shipping at truckshop? from my calculations since suicide doors has free shipping, it will cost 127.96 as opposed to truckshop including shipping at 129.93. it is only $2, but every bit counts when you are on a budget.

 

at truck stop they list that the SMC valves come with the brackets... suicide doesn't list that they do, i'll email em and see if they do

 

i see, also what i noticed, if you only order valves from suicide doors, it's free shipping, but when you add things that aren't free shipping, the shipping price includes EVERYTHING. might only affect me because i live in hawaii, but i might have to make 2 orders, 1 for the free shipping stuff, one more for the others.

 

i noticed that too when i added in the viair 400 with free shipping, with the tank and DOT lines the shipping jumped 15$ when i added the compressor

 

if you know anyone my 2005 bagged xb is posted in the classifieds for sale.
