Absolutely. If the fuel system pressure is dropping due to an overly clogged filter or pump problems then the injectors have to stay open longer (and would look like more fuel going into the engine).

Same is true if the injectors are getting clogged, they have to spray longer to keep the o2 sensor happy.
