Fuel problem?

[mrcrx28]

Gas mileage is very bad, I can see the needle going, also fuel smell in the car, only on a full tanks. Back fires once awhile, normal? Running a SR with upgrade fuel pump and 300z fuel filter.

Do you have an SAFC? Check for leaking injectors or leaking hoses especially in the back where the fuel pump is.
