My TD used to vapor lock badly in hot weather/low speed driving. One of the
first fixes I tried was a heat shield but it provided little if any
improvement. The ultimate fix was to install a second electric fuel pump
directly underneath the fuel tank where things are nice and cool. This pump
provides a pressurized fuel line to the original fuel pump instead of it
having to suck fuel up the long line from the tank. I have had zero vapor
locking since. The added fuel pump is essentially unnoticeable unless
somebody lays on the ground and looks up under the rear bumper area. Be sure
to put a gas filter ahead of the new pump.
