Most likely the threads in the carb are 1/8" NPT. That will actually measure around 5/16", as the size roughly refers to the ID of the fitting. Finding one with a screen tough will have to come from a carb shop or the dealer.
The orings you added to the other fitting, probably not going to work. Keep looking until you find the right fitting. Short cutting fuel lines over a hot engine, with a gravity feed bottom tank fitting, not a good practice.
But as for using the old pump, even though it appears to work, I would go ahead and replace it. If it's been running open, no fuel through it, dirt and whatever that may be inside, dried up diaphragm, asking for trouble trying to use it.
Not only will it release whatever is inside into the carb, if (when) the diaphragm goes, it can fill the crankcase with gas, and drain the tank on the ground, or worse!
The old mechanical pumps don't like ethanol gas to begin with, so please, start with a new one, not worth the chance!
