I've recently picked up the Autometer Fuel Pressure gauge. As I opened the box and looked at the pieces I noticed that the sender unit is a small cylindrical thing with a threaded part at one end while the other end has the electrical prongs. What do I use to attach the sender to the vacuum hose?

You need to make a Tee adapter that you thread the sender into, and then cut the fuel (not vacuum) line in between the fuel filter and the fuel rail and insert the Tee at that point. I believe the fuel line is 5/16ths, so use appropriate size hose barbs for connecting the Tee to the fuel line. Pepboys usually has a good enough selection of brass fittings to make one.
