Ford 94 carb and vapor lock

[The Art Doctor]

Modern fuel is engineered for closed loop modern cars. Its vapor pressure is set low to easily evolve in that closed loop. Our open loops allow the low vapor pressure fuel to easily evolve out of the system and into the atmosphere where it does little good to start the car. It also evolves into a gaseous state in a hot fuel line creating a blockage to liquid flow, "Vapor lock". You have a fuel problem. Actually a lack of fuel problem, even with a full tank. To fix that fuel problem you need an electric fuel pump to fill everything back up when empty and secondarily push past the vapor lock created when the fuel vaporizes in the line due to hot engine compartment temperatures. Electric fuel pumps are not a point deduction in EFV8 judging because they are a necessity to ease of usage and functionality in the modern fuel world. I have one in each carbureted car on a switch for activation when needed except during the summer when I leave them on all the time or the car would be stumbling continually; its hot here.
