I replaced the vent lines on my fuel tank and evap system last year with this:

"Cloth Braided Fuel/Vacuum Hose - Black - 5 Meter - 5mm ID"

This stuff is, frankly, crap.  It's already starting to crack at the
ends, and I think I can smell fuel vapors right through it.

Can anybody point me to the right stuff to use?

Thanks as always,

Alex
