MG Midget and Sprite Technical - Leaking Fuel Pump

Hey Everyone,
Fired her up for the first time on this (FINALLY!) beautiful sunny Sunday in Toronto.

Noticed a fuel pump leak. (mechanical pump) Pulled it. Cleaned it. Checked gaskets / rubber seal. All good.

Then noticed this. One side sealed up...other has a hole. But when I cover it, it changes the pumping action. Should it be open like this or sealed up?
TIA!

thats the vent for the outside of the diaphragm its the same on my old one. If it leaks from here the diaphragm is split like my old one
Alan McKewan

short answer... "yes" there SHOULD be a hole there?!
