What tubing for direct port?

So I have my DP setup plumbed already, did it over a year ago. Well, long story with the car, just never used it. Now I want to redo it (yea I know). The SS 3/16" tubing around is $3-4 per ft. everywhere I look. How different is that tubing from the stuff they use for brake and fuel lines? Summit has this on ebay for slightly over $1.00 per foot which is a heck of a lot cheaper. Will it work? If this stuff is strong enough for brake lines, I would think it would be fine for nitrous. Is the wall thickness similar or the same?

Help me out here... I'm looking to save a few bucks.

yes it will work...as long as the dimensions are the same...inside diameter and outside diameter

it is very possible that I stand to be corrected but I thought dirrect port uses 1/8 tube

I accidentally purchased a few packs of 1/8" and realized it wasn't the right size, at least for my application. I'm having trouble finding a measurement for the tubing that comes with the kit from NOS, so thats why I am asking. Anyone else know for sure?

it is 3/16 O.D.....not sure on the I.D.

I would go measure the original tubing if I had something accurate enough to measure it with. I did see this morning that they rate the brake line to 250 PSI, which isn't enough. I'm guessing that this stuff isn't going to cut it. Anyone know where I can find the best price on some SS tubing?

Easy way to tell is by what type of jet you are using. If it's a flare jet it will be 3/16 and if it is a funnel jet then it will be 1/8. Brake line should be ok but the flare may be wrong a standard AN fitting is a 37.5 degree flare. A 45 degree can seal on a 37.5 but it will be an interference fit which isn't the best thing in the world.

With the brake line I would be able to flare the end to whatever size I wanted though, correct?

You should all as long as you can find the right flaring tool. Although brake line is thicker and would probably be harder to bend.

I think that should work fine for you.
Some tractor places have all the tubing and flaring tools you need, they also cary 37* fittings but not much aluminum

I mean, the price difference on this stuff is huge. That summit stuff is exactly what I was looking at and its about $1.00 per foot, as opposed to 3,4,$5.00 per foot for the other SS tubing from the nitrous stores.

I guess I don't fully understand this flaring problem though. I have a flaring kit, but your saying that the standard flaring kits create a 45* flare and the AN fittings use a 37.5* flare, correct?

Correct. That tubing from summit looks like it comes in a roll in which case you may have a hard time straitening it out to use to plumb the manifold. You can get the NOS 16360 for between $15-20. That is the 8 pack of 12" steel 3/16 line. The flaring tool is not something you could probably find at the parts store so you would have to go to a speacality store. And by the time you buy that and the tube it may be cheaper to buy the actual tubing.

I just found the tool on eBay. I still need two packs of the NOS tubing though, and I would really prefer the SS because the steel that I used the first time is already starting to corrode and I haven't even used the system yet, and have barely even driven the car.

Plus I think if I can get the blue anodized brake line, the setup would definitely look pretty trick!

Also, when this is rate to 250PSI, why do people think this will work?

That blue line is the wrong size and the wrong material. If you get that flaring tool for $6 it would be a great deal that is a $100+ tool. And again if you are worried about how it looks I think you may be disappointed with the way the roll of SS tubing ends up looking. If it is indeed a roll it will not be very easy to plumb and make look good. SS does look good but it is expensive. You might try and industrial supply store and see if they can get you some SS line in the right size.

I have used the rolls of tubing from summit....it is rolled on like a 12" diameter so it straightens easily....they also have the 37* flaring tool there also...I will try to post you a link to it

you want the slainless steel line don't use the anodized its aluminum...not strong enough

Alright, sounds like I will give it a whirl then. I should be able to polish that SS real nice too I would imagine.

Why not use poly line if your trying to save money?

What exactly do you have in mind? What will hold enough pressure? I'm not dead set on this stuff, just looking for options.

Some of the DP kits such as the nozzle kit comes with poly nitrous line for easy routing, dont know what kind of set up you have but i guess its an option for ya. Easy to change jets too.

Ok, I have seen some of those. I'll have to take a look.

If you use the poly line you will have to get funnel jets, so keep that in mind when figuring costs
