Wow, was I lucky! Audiovox.

Still winter here and the farklizing is just beginning for me. Installed the Audiovox CC last winter and it worked fine all last season. This winter after pulling off the plastic to install a quartet harness and cigarette lighter type power jack, this is what I found.

The CC vacuum cannister that I built out of some old vacu-flo piping (2 inch diameter, styrene? plastic, about 5 inches long) totally collapsed. BUT, it still holds a vacuum. It must have deformed over time. It was tucked up behind the left side of the dash, so I don't think that heat was an issue. This would have been a real pain to fix on the side of the highway somewhere, raining probably.

I will replace it with some sturdier ABS drain pipe plumbing shortly. Lots of hills here in the west, and I tried last spring with and without the cannister. It made a difference.

Lucky me.

Wow. That looks alot like heat deflection.
BTW ABS is styrene with rubber added in. It would be tougher but not stronger with a given wall thickness.

Hi Jev,
Had the same myself last year, swapped for a metal container in the end, in fact it was an old brasso tin, did the job just fine as it already had a threaded neck. I screwed a tyre valve straight onto the threaded end and removed the internal valve parts. It's been a year and so far so good.
It's always nice to find a fault before it cause's a problem, Happy farkling.

That is so cool.

Probably enough vacuum and enough heat.

Nice picture. Murphy sells a canister for around $10 plus shipping. Worth it to prevent this from happening on the road or to even have to pull that darn fairing off. I installed the vacuum canister on the right side in the upper fairing above the horn.
