Mine is a 95 Rio Grande 2.5l and I have hoses going straight to the firewall. There is a tube about 5 - 6" coming up from the top of the pump that goes along left side of the valve cover (and normally is rusted and brakes very easily by now) which one of the hoses goes on. It sounds like it's a 2.5 with a carb rather.
