Curious......

The header tank vent line on our S-7 which goes to the starboard fuel tank top is made of some version of tygon (near as I can recall from previous laboratory work, there are about a zillion version of tygon).

Has anyone swapped this out and used a standard fuel line in its place?

Wondering about this since the type of tygon used does not have any reinforcement (some types of tygon do).

A person can cut anything tossing a sharp enough object in the back hard enough (passengers), but since a standard fuel line has reinforcing braids between the layers it would seem to be a bit stronger. Also wondering if it has ever happened having a less than brand-new tygon tube snap due to cold weather or embrittlement with age.

Thanks for your feedback,

Sincerely,
