Silicone vacuum hose

[Rock Trol]

Has anyone used silicone vacuum lines and how do they compare to the rubber lines. i noticed on the weeken that my boost was very low (about 6psi) and I tracked the problem down to the vacuum lines connecting the dawes valve. They had gone soft and were losing vacuum. Trimmed the ends off and reconnected, boost back to normal.

I found the same and fitted 1/8 high pressure polyethylene pipe.
Silicone was just to soft and flexible for the small size.
