Just to continue the vapor lock talk, I don’t think my early BN7 had a heat shield on it as OEM. So several years ago after not driving much in the hot summers due to vapor lock issues, I bought a used but good heatshield from someone on the list to put between
the carbs and the intake manifold.
<div>I have yet to put it on as it sits on the pile of “to do” things but I am sure it would help as well.<br>

<div style="color:black;font: 12pt Comic Sans MS, sans-serif;">I am going to assume by "draw heat away from the fuel line" you mean they block the heat from the exhaust system from being absorbed by the fuel line. That would mean that they act as an insulator
between the heat source & the cooler fuel & fuel line. A cloths pin is about 1/2" wide. To have any measurable effect at all you would have to line the fuel line with cloths pins for several feet.
<div>The purpose of a heat sink is to rapidly transfer heat from the heat source (exhaust) to another fluid (fuel line). Luckily, wood is not a good material for a heat sink. <br>

<div>clothes pins act as a heat sink and draw heat away from the fuel lines. easily moved about to locate best location.
