I haven't seen a true case of vapor lock in years...and i own a
shop.
Vapor lock (also called percolation) occurs when the gasoline in
the fuel line boils. the fuel must get very hot for this to
happen.
Usually it happens on a hot summer day and the fuel line is
placed too closely to an exhaust manifold.
In almost every case of vapor lock i have ever seen, the car was
not fuel injected but carburetted.
The cure is to re-route the fuel line away from heat sources
under the hood.
But i must say that i would be surprised if you have an actual
case of vapor lock. It is rare.

Asked in Asian Cars
Why do you always get a vapor lock on your 1977 2.0 when temps over 85?
Older fuel pumps suck the fuel from the tank to the engine, and
push it from the pump to the carb,and are susceptible to vapor lock
because of this ( suction).
You can reroute and insulate the fuel lines so they stay cool,
but the best most permanent way is to install an electric fuel pump
as close to the fuel tank as possible, that way it is a pressure
system and not prone to vapor lock.
Asked in Locks and Latches
Does a vapor lock lock you in or out of your car?
Vapor lock occurs when the gasoline vaporizes between the tank
and the engine. This occurs when the fuel line is routed around the
engine so that the fuel is heated to the point of vaporization.
When this occurs the engine will run roughly and will lack power
because of the inconsistent amount of liquid fuel reaching the
carburetor's, or fuel injectors.
