Default Metal carbon-canister gas fume Y?

Do I remember correctly that at one time there was a metal replacement for the "Y" connector at the carbon canister inside the wheel well that often breaks and makes the cabin smell like gasoline?

Is it still available?

Should it be?

It should be, but isn't.

The cost to produce them was too high for the price point and no longer became profitable and instead became a loss.

Thanks, Blake.

If someone will loan me a plastic one, I'll make a 3d model and upload it to shapeways.com to see if just-in-time 3D printing would make sense.

I used to be the source of the metal Y connectors. Cost of labor for cutting and welding is subject to supply and demand. And demand up here is super high. Stainless tubing cost got seriously expensive too. The first few runs were done for labor dollars only and the surgical grade SS used was otherwise scrap left over from bio-lab builds.

New plastic part is $18-20 now IIRC.

Thanks, Dave. It looked like a lovely part. I'm sorry I didn't grab one when they were available.

Do you have a drawing you'd be willing to share?

Yeah, theoretically. If I can find it, I will post it.

Here it is...

This is a drawing with basic measurements. It is not a drawing of a perfect replacement. The 'real' plastic part has barbs.

An .stl is here: https://www.dropbox.com/s/uago5d896r...0Pipe.stl?dl=0
Shapeways can make them in steel for about $32 shipped. Would anyone be interested?

If not, I won't spend any more time on this—I don't need one just yet, and I will order one from Shapeways when the need arises.

Mark,
assuming they are making them in stainless,
please put me down for one.

I don't see that stainless is an option.

Here's the Shapeways order page.

I'm not vouching for the ring I've added to hold the hose on the pipe (simpler than barbs) until I've printed one and tried it out.

Whether you need (or want) barbs on the ends is debatable. There's virtually no pressure on the system, the hoses are soft, to the point where zip ties are plenty with smooth pipe ends. Particularly the hard plastic tube between the canister and the Y, you definitely want a smooth pipe to slip that over. I replaced that section with hose when I did this 20+ years ago now.

The plastic factory piece I installed way back when has held up perfectly in the intervening period. Keys for me included adding extra support to all the connecting hoses, essentially eliminating the strain and vibration that caused the original Y to fail. I don't want to tangent from this thread about a metal piece, but will share that some other threads on the y-pipe subject include my documentation write-up on the project, with a detailed procedure and pictures.

Or, for 79 cents you can use a barbed nylon T.
