The basis for the upgraded fittings was that the supplied fittings and hose and method of attachment were something less than desirable. The value in this thread is not meant to be that of the Catch-can, but in that of the techniques used to cleanly install the selected AN-style fittings.
So I got this done yesterday, it took a bit longer than expected, and while in the end I'm satisfied, I'm not sure it's the 100% answer I was looking for. Primarily, while I really like the style of the fittings, they are quite large compared to the brass fittings. While the brass fittings are small, compact, they are a bit crude...
It took 3 hrs, and that includes stopping for lunch and scratching my chin on how to deal with the PITA of cutting the hose... While the hose is much nicer in appearance and more flexible than the heater hose, it has an inner steel braid that makes cutting it "challenging", you'll find some that suggest cutting it with large electrical cable cutters, not only does this not work well, the end result sucks, badly....
As I said, the first challenge to overcome was the hose, I ordered it (and the fittings) up from Summit, although I'm sure others have them as well. I ended up using a cutoff wheel, and the results were very nice, with the only down side being that you've got to clean out the inside of the hose, which isn't difficult to do if you have compressed air available...
The cuttoff wheel is a 1/32", what makes it work is that it has a fine mesh to it, it melts the nylon and rubber while cutting the steel braid. The 1/8" wide wheels are typically a coarse mesh and don't do as clean of a job...
This is what you get if you go with cable cutters... (crap)
I saved my original OEM hose and fittings so I could go back as needed/desired... I ordered up a replacement hose from XXXXXX, they had one on the shelf and I cut the fittings off of it to use in this setup...
Bob's Catch Can, with the AN fittings installed. I noticed that the clocking of the two ports isn't quite perfect, no harm in the end... Keep in mine that the two halves are threaded together and the threads on the two lathe turned parts have to be perfectly timed to then make the ports line up. If you tighten the two halves differently, then the ports with be different...
Installing with a 17mm deep well and a flex head crapsman ratchet... The little bit of rotational play shown in the mounting bolt helped make things fit well in the end by being able to fine tune the position of the can. The hoses are flexible, but with short lengths like this, they still can be difficult to get exactly right...
Sizing up the first hose...
Installing, with AN fittings, position the hose as such, then thread on, tighten and check for excessive hose movement, this is about as much as you should allow for. Given the nature of this installation, (low press and vapor, no liquids) I accepted the little bit of push out... (Oil up the threads and inner hose wall with light oil)
The AN fittings are swivel fittings, so I was able to rotate them around at various points along the way to make it easier. The fittings are easily damaged, so use something like painters tape to protect their finish..
This is the method that Bob's promotes for a hose clamp, it's much nicer and cleaner than a worm-gear style hose clamp, but they're one use only... You have to collapse the inner tube to get them off, you'll destroy the Power-Grip part if you try to slide it off the tube... Use a screwdriver to hold it in place while you use the LOW setting of an industrial heat gun (I ruined one with the high setting)
It's basically a HD piece of heat-shrink. Gates sells them to be used on heater and radiator hose, they should be more than good enough for this application...
First hose installed....
Second hose, pay attention to the routing, if you put the harness on the other side of the second hose, it gets bound up... (Sorry about the picture rotations...)
Cutting the second hose to length... About the same amount of push-out as the first hose, again, acceptable by the AN standard for normal use, more than fine for this application.
The hose pushes on this sensor a bit more than I'd like, but keep in mind, if you were using the heater hose, it'd be worse as the heater hose is stiffer...
