This is interesting. I think I have the same system as Paul and you
(With the Andair gascolator) except that I have an additional disposabel
filter for the secondary fuel pump. We are talking here about the series
configuration, right?

Well, it could be that the fuel filters are contaminated (although I
cleaned/replaced them just 40 hours ago) causing enough restriction in
harsh conditions but not enough to cause a fuel pressure drop at lower
temps/altitudes. Or I just had a bad batch of fuel.
I will check the system thoroughly and see if I can find any abnormalities.
