no the vac line doesn't have gas in it, nothin to leak but air. its a petal valve, there is like a little diaphragm, sometimes its a pumper but usually just allows flow only when the vacuum pulses from the cylinder draw it open, you can bypass it by sucking on the line, youre sucking under the diaphragm on the dry side to draw it "open" and check that it lets gas flow any cracks and it loses vacuum and doesn't draw it open
