A way to minimize (I'm too old to say completely eliminate!) vapor lock is to insert a three line filter at the carburetor, and run a return line from the "vapor" port of the filter back to dump into the fuel tank.

Am not aware of anyone who has experienced vapor lock after making this modification.

Good carburetion is fuelish hot air
The most expensive carburetor is the wrong one you attempt to modify.
