Best setup I have found so far for vapor lock is do away with the factory pump.

Install a good electric pump back by the fuel tanks-can use 2 pumps or a switching valve.
No fuel filter between the pumps and the tanks. Up front where the old pump used
to be install a 3 port fuel filter-3/8 inlet/outlet with a 1/4 return-they are a bit
hard to find. Then run a new line off the 1/4 side of the fuel filter all the way back to
the gas tanks and dump into the tanks.

Works well and this is where I got the idea from.
