5 year rubber alternatives

[seagull]

I didn't think the Teflon fuel and oil lines had a life limit. Do they get replaced at 5 years?

Silicone is a good material and lasts well. It is soft, though, so tight hose clamps can damage it and it is not as abrasion resistant as epdm.

Mike----I have to disagree. The 912ULS uses the VA216 return hose, the 912IS uses a VA138.
The VA216 is a -4 with a restrictor for carbureted applications. The VA138 is a -6 without a restrictor for the injected models. Yes, both are teflon, and NOT service life limited. Yes----be prudent, and inspect them for outside damages.

Is there a time specified on the oil lines or are they on condition / inspect for outside damage?
