Hard starting when engine and ambient temperature is hot.

[Hoffman Anthony J A1C 552 CMS/MXMVC]

The one other possibility is the fuel accumulator, under the rear seat area.
It has two lines running to one side, and a tiny straight-blade screw on the
other. If the area around the screw is wet, the diaphram is broken, and it
needs to be replaced.
Having said that, it is most often the check valve, and a diaphram can be
bad for a while before it shows vapor lock symptoms.

Fuel pressure check valve.  In the gas tank on top of the fuel pump.  I went
in with a new one in hand and found that it was merely loose.  I replaced it
anyway.
