1995 Plymouth Voyager Fuel problems

Engine Performance problem
1995 Plymouth Voyager 6 cyl Two Wheel Drive Automatic

My mom and dads voyager had been smelling like it was leaking fuel and I found that the hoses on the fuel filter had been worn and were leaking. I replaced the filter and the hoses but now there is no fuel getting to the engine the pump is good the in jector is good I think there may be a vacuum leak but I have no idea how to check or identify where that would be please help.
