The OEM Fuel Level Sending Unit assemblies have been discontinued by Nissan USA for years now. While the pumps themselves are serviceable, this does little to address the issue of the float sensors failing. After 30 years, we have found most of them have dead spots and inaccuracies now.

Thankfully, we have discovered full OE replacements from V12THROTTLE, who makes similar products for a myriad of classic vehicles. While these are not original Nissan products, we feel these are the next best option. So here's the rundown:

• Compatible with all 2-seater models (TT or NA, including convertible)
• Includes a new fuel level sensor & float assembly
• Premium zinc-plated steel construction
• PTFE coated 14awg wiring

Our Experience & Recommendations

Like with any aftermarket product, there are always slight differences to note, compared to stock. Because of the complexity involved with these assemblies, we tested these on a few of our personal vehicles here at CZP, and here are some observations we made:

• The level sensors have small tabs that act as stoppers to keep them from going up or down too high. We noticed that it's POSSIBLE for the stopper tab to catch on the side of the sensor assembly when moving upwards. However, it's not really possible for the float to go too high in actual use, so we think it's a good idea to trim or clip that little stopper tab to prevent it from catching in use.
• We tested the sensor calibration and confirm it matches the OEM sending units, both by comparing our measurements to a stock unit, and comparing against the values in the factory service manual to make 100% sure they are in spec.
  
• Because of the saddlebag design of the factory 2-seater fuel tank, it can take a while for the levels in the two halves to normalize after servicing the pump & sending units. We recommend filling it up after installation, and then drive it around for a few days to let fuel slosh around and let the venturi on the pump do its job.

Note: The 2-seater Z32 runs the two level sensors in parallel with one another: one coupled with the fuel pump on the LH side, and one standalone sensor on the RH side. You can test yours using the table above and, if needed, the pump assembly with a new sensor is available HERE.
