I have leftover McMaster-Carr 4463K123 from my recent fuel system refurb, great for insulating the return line from the fuel pressure regulator to the tank. I'm offering 13" lengths for $1 plus the cost of shipping, or $6 total.
(Note, McMaster-Carr's price is $2.76 for 6' of insulation, but the shipping was $17.00 for the insulation plus a box of hose clamps. Yikes.)
