if you have excessive fuel consumption there are a possible number of things you can check out:-
1-check that there is no external leak in the fuel supply system-check all components for signs of leakage
2-check the air cleaner to see if it is blocked, if blocked clean or replace with new element
3-engine may be running too cold due to a faulty thermostat
4-you may have high fuel pressure. test pressure, if high check fuel return line and fuel pressure regulator
5-you could also have an exhuast system blockage-check system for blockage
