How to make a hard BOV recirculation pipe

I wrote this a long time ago, back when I first got my FMIC, on DSMTuners.
After switching to the SS Autochrome/XS Power FMIC, the piping placed the BOV in a downward angle, and I couldn't get the stock recirc hose to fit correctly. I had a crimped radiatior hose on in place of the stocker, but it was a POS. Well, after 2 hours of work and 2 trips to the store, I have the solution to your bov tube if it is crimped, or you are venting it with this kit.
Total cost of project : $12.35 (might be less if you already have some parts)
Alright, the parts/tools you need are as follows:
- 2 feet of vacuum hose
- 6 1.75" hose clamps
- A long enough piece of rubber hosing, maybe atleast a foot, to use as couplers. (I used a radiator pipe and cut it).
- 1 "P Trap" tubing kit with 1.25" inlet/outlet. (Got this in plumbing section of Lowes home improvement store)
- The normal wrenches/sockets you would need to install a bov
- Hacksaw/cutting tool
- Sander/metal file
I'm sorry I didn't take step by step pictures during installation cause I forgot my camera, but I think the pictures explain this very well. I am also just trying to remember from memory, so take precise measurements when cutting.
First, you will need to remove the bov from the flange on the IC pipe. Turn the bov around so that the outlet port is facing the windshield. Now, remove the old vac hose for the bov, and replace it with the longer piece you have and cut it to the proper length needed. Bolt the bov back down to the flange on the IC pipe.
Next, cut the smaller pipe in the "P Trap" pipe kit so that you get a 180 degree bend out of it. This piece will be going on the outlet port of the bov. Next, cut the rubber hose you have to use as a coupler. Each cut should be approx. 3" long. Then, cut the longer of the "P Trap" pipe about maybe 1.25" off of the side without the flange on it.
Connect all of the pipes together with the rubber hose couplers and secure them with the hose clamps, and you are basicly done! Just make sure to check for leaks and if everything is tight. Pictures are below:

This exact way will NOT work for everyone, since no one is running the same setup. This writeup is just simply a guide on how to make your own custom piece.
