Service Procedure: Overview

Fuel filter inspection/replacement for the 300ZX and Maxima

After installing a fuel pressure gauge and checking the fuel pressure, inspect the fuel filter. If the fuel filter shows any sign of leakage or is not designed for this specific application, the fuel filter must be replaced. Fuel filter requirements for this specific application are:





a. All metal construction (Nissan is concerned that a plastic fuel filter may be damaged during hose replacement and any damage may not be easily detected).

b. Flow through design with the inlet and outlet fittings aligned on the filter's center line.

c. Fuel filter body diameter of 2.25 in., and fits the fuel filter holding bracket securely.

NOTE:
If the fuel filter is replaced on the 300ZX, the frame-to-filter hose must be replaced. Refer to Related Parts information in this bulletin for the correct part number.
