When I get home, I can break out my Factory Service Manuals and give you the factory test instructions.
You should NEVER
have fuel coming out of the nipple on the vacuum side of a FPR. There is a diaphram in the FPR with fuel pressure on one side and engine vacuum on the other and "Never the t'wain shalt meet"
. If you are getting fuel leaking past the diaphram, it is unmetered fuel being injested into the manifold. Your therefor running rich. Hence the hard hot starts. Much like trying to start a warm carburated engine with the choke on.
