Plastic tubing inside autogage sets? good or bad

[wazazzle]

Anybody ever have the plastic tubing in the autometer gauge sets go bad on them? I was reading a thread that they harden up and crack eventually - spilling oil into the interior. Is the tubing good or not good? Also is there an alternative like flextubing-etc, besides going electical?

.... had the line on my mechanical oil pressure guage go bad (mounted outside) and have since switch to a stainless braided line.

My mechanical Autogage oil psi gauge came with a plastic line. I promptly tossed it into the trash and used the $8 dollar Autometer copper line kit. That is the cure to your concerns.

Go to www.summitracing.com and search this pn: ATM-3224 It's $9.00 now.

Why not go with an electric gauge?

Little more $$ but probably worth it.

Yes they might go bad. I have my oil gage inside but will be switching to the stainless steel line.

On the other side of the question at hand, I have had the nylon line going inside the cockpit on another car for over 10 years of use. No issues.

As amply depicted, copper and braided are the two normal alternatives.

Good luck.

No not me personally. But a friend of mines did. Oil all over the friggin place.

I don't use mechanical gagues anyways.

Can always run down to your local ACE Hardware and ask for some 1/8" copper tubing and two brass ferrules. Have had the same piece in my '66 for 26 years now - no problems

not to get off topic or jack the thread here, but this got me thinking, that plastic and copper tubing for the guages, it wouldn't happen to be about the same size as those crappy stock plastic vacuum lines would it??
