I was having lots of vapor lock issues with my 51 200. In an effort to combat it, I made sure the fuel pump had the fiber insulators around the bolts, lengthened and rerouted the fuel line so that it wasn't above the manifolds, slit a rubber fuel line length wise and put it around the fuel line, and added another carb insulator for a total of two (these are the old fashioned ones with asbestos). All of these seems to have done the trick.

Long story to explain that the thickness is variable, but thicker is better in my opinion.
