My recommendation is to install an electric pusher fuel pump at the gas tank. This will push liquid fuel through the vapor lock area to the mechanical pump. IF you really have a vapor lock issue. If the electric fuel pump solves the issue, then it was vapor lock. If it does not solve the issue, then you have a different issue. An electric fuel pump is good to have in the base case. Wire it switched so you can use it when needed.
