My 1996 does not have a recommended mileage or time to change the fuel filter, bought it new over 18 years ago now and still using the original fuel filter. Fuel is getting to the LT4 injectors just fine. After getting the 1996 Corvette and seeing there was no gas filter changing, I did not worry about changing the 1985's fuel filter.
