that may be tough, every pcv i've ever seen was a push-in, grommet style... and yes, the threaded fitting is pressure...

as for your ps pump, you could find a rubber plumbing cap and hose clamp for the top, a threaded pipe cap for the preasure line and for the return, a small amount of return line with a bolt stuck in the end and a small hose clamp around it...
then you could pour like half a quart in there and cap it all off so it doesn't run dry

Got my evac can and fresh air supply can back from my welder fab guy. He TIG'd em and they look nicer than I could have done with my MIG.
the fresh air can. Simple with a filtered breather, and each bottom port will go to the small tubing nipples on the valve covers, toward the back of the V.C.
The evac can has two internal baffles in it, and the top port will connect to a PCV then to the base of the carb.
The valve covers with breather/separators toward the front, and the fresh air intake hookup to the rear.
