Many years ago I had a Carter rotary fuel pump, differrent model,
somewhat larger, which made a hell of a loud whining noise. I have
no experience with this smaller model.

You get carburetor problems with higher pressure. SU carbs like 1.5
to 3.5 PSI fuel pressure. Going over 5 psi is almost guaranteed to
make the floats overflow at certain resonance frequencies (mid range
engine speed).
For a replacement fuel pump I like this one:

My only personal objection to the original SU fuel pump is the
contact points which tend to corrode and kill operation of the unit
if it is stored for several months (or longer). If you store your
car for 6 months each winter it can be a royal pain to clean the fuel
pump points every spring.
