However, it's important to note:
* Always disconnect the negative battery terminal before starting any fuel system work.
* Some repairs might require partially lowering the tank for better access. While you don't need to fully remove it, you might need to loosen straps or use a jack for support to get sufficient room to work.
* The difficulty of accessing the fuel pump varies. Some people find it easy; others struggle.
* Consult a repair manual specific to your 1993 Nissan 300ZX. This will provide detailed instructions and diagrams that are crucial for the job. Improper removal can damage your fuel lines or other components.
In short, while a complete tank removal isn't typically necessary, be prepared for a potentially involved process that might require some maneuvering. Use a repair manual and prioritize safety.
