The fuel level 'sender' is the sensor in the tank. It does not incorporate a fuel line, although the coupe sensor has a fuel vent fitting. For the fuel outlet line, see Fuel tank.

Wiring
There is a single Yellow wire on the sender. It goes forward to the dash Fuel Gauge. This wire is grounded through the sender resistance.
See main article: Fuel Gauge Wiring
Sender Specifications
As measured by club members, by moving the float up and down from stop to stop:
- 10-12 ohms fully up
- 88-100 ohms fully down
- 35 ohms half full (per Nissan Factory Service Manual)
NOTE: This does not necessarily match "Full" and "Empty" marks of the fuel gauge, due to normal manufacturing tolerances. Typically a 1200 reads well 'E' before it runs out of fuel, this is normal.

Fuel Gauge Specifications
From the 1973 Datsun 1200 Factory Service Manual Ohms Mark 35 Half
Stock Fuel level gauge, ss measured by club members: * Empty mark: 73-88 ohms input * Full mark: 12 ohms
ang94541 uses an aftermarket Autometer 3515, which seems to match the Nissan sender. It is designed for the 1965-1985 Ford senders. Also used by Chrysler and VW beetle (73-10 ohm gauge).
