fuel pump questions..

Been experiencing lower than expected & previous boost levels.
Usual culprits seem to check out as OK.
Worryingly the sparkplug tips are whitish.. Leading me to suspect lean/fuel pressure/delivery issues.. which invariably points to the the pump ??
Car has 105k miles.
Pump feed /return elbows were replaced last fall due to a wee but smelly leak.
Unlike the earlier Bosch pumps these later ones don't seem to make the 'I'm dying' noises.
Not keen on blindly throwing parts at it?
Even if only because that approach has never worked for me in the past :-)
ANY way of actually checking the pump function, in the absence of a fuel press gizmo/tool ?
