How to Build Stainless Braided "AN" style lines for any application

So, You want to build Oil Feed and Drain lines for your new Turbo setup? Or maybe Fuel lines? or Brake lines?
Here is a quick, pic based tutorial on how they go together.

For this How to, I am building an oil drain line for a turbo setup.

First, a quick tip.
Once you know your fitting sizes, ect, and are ready to buy your fittings for the hose ends, I would highly suggest always buying "Swivel-Seal" style hose ends.
Here is why.
When you go to install your lines, if they are not perfectly straight and in line with the fittings, when you got to tighten them down the whole hose and fitting will want to turn, making it very difficult, or sometimes impossible to tighten down without spinning and kinking the line.
The Swivel-Seal hose ends are more expensive, but believe me when I say, they are worth it.

So, for this particular line, I am using -10an line, and fittings.
First, your gonna wanna cut your hose to the appropriate length.
Your gonna wanna tape the end of the hose with some masking tape or somthing so that the ends dont get all frayed when you cut it.
Use a Cut Off Wheel, or a Hack Saw with a fine toothed metal blade, and you'll end up with somthing like this:



Next, you take apart your Hose End, it will look like this:



Then you pull the tape off the hose you cut, take the red part of the fitting, and push it onto the hose, being careful not to seperate or damage the braiding, like this:



Until its seated all the way in, like this:



Next, You'll wanna either mark the hose with a marker, or with a peice of tape, just behind the fitting you just installed, like this:



So that when you perform this next step, you can be sure your not pushing the hose out of the fitting.
Next, take the blue part of the fitting, and install it into the red section, like this:



Sometimes it helps to lube the end of the blue fitting with a tiny bit of oil if its really hard to install.
Begin tightening it down slowly, checking to make sure your not pushing the hose end off the hose. When your done, it should look like this:



And thats it!
Depending on the size of the hose your making, it can be difficult to tighten them down, so I like to put the hose end into a vice, and use a wrench on the fitting for these larger hoses.

Now, here are a few common sizes I've used building diffrent lines over the years that may be helpful down the road.

Most Turbo Oil Drain lines will call for either -10, or -12 hose.
Turbo oil Feed lines should be either -3, or -4, depending on the manufacturer. precision turbo reccomended -4 for theyre 5857 turbo to me, I use -3 for my 5sfte setup, with a restrictor.
For 99.9% of the cars here, -6 line is perfect for fuel line, thread pitch for both the top of 6gc fuel filter, and 3s/5s fuel rail is 12mmx1.25
3rd gen 3sgte oil feed thread pitch is also 12mmx1.25
2nd gen 3sgte oil feed is 18mmx1.5

Enjoy!

Good write up, one thing i'd suggest is using a chisel to cut the ends instead of a cutoff wheel.


No tape necessary, no metal shavings inside the lines. Chisel/sledge two solid hits and it cuts.

Just gotta make sure that chisel is SHARP though. Otherwise, you'll be pounding on it for awhile and will end up pinching the hose.

Good write up though, Manny! I'll be making the fuel lines here soon.
