Re: 30 year-old foam is no longer supple ('79 W123 ACCII temp sensor)

The foam tube is the aspirator tube for the climate control - it draws
cabin air over the inside temperature sensor and exhausts same into the
blower intake. A piece of 5/8" drip irrigation tubing will serve as well
(but not as quietly).

For a quieter version, use a piece of foam home hot water pipe
insulation that is sold at Home Depot or similar stores and made to go
around home copper water lines. Don't remember the exact size I used,
1/2-3/4, but it fits perfectly.

Ok, I wondered if this was state of the art for this sort of repair. :)

I thought I might look for something softer, more like the original
hose, but figured pipe insulation would work in a pinch.

thanks,
