On a carburated engine it is a huge waste of time to test fuel pressure. If the fuel pump is pumping a good amount of fuel out, you have enough pressure. Much easier to do a flow test and you can do a visual test of the quality of the fuel at the same time.
15 lbs of vacuum is defiantly a problem!!!!!! 15 inches of vacuum could be a vacuum leak which, would give you the same symptoms as lack of fuel. Check the base gasket.
