TN/L3 280 TN Sensor – L3 Series Fuel Gauge 280MM
The TN/L3 280 TN Sensor – L3 Series Fuel Gauge 280MM shows how much diesel is left in the tank without any power supply. (280 mm long)
About this part
A level gauge tells you how many hours a generator can still run, which matters most during long outages. Mechanical gauges need no electricity; versions with a sensor alarm add a low-level signal for the controller or a buzzer.
When to replace it
- New fuel tank
- Gauge stuck or reading wrong
- Adding a low-fuel alarm
Before you order
Measure the internal depth of the tank and choose the gauge length to suit. Check the thread or flange on the tank; mounting flanges are available separately.
Match the number stamped on the part you are removing, or the number in your engine or alternator manual, before ordering. Part numbers are shown for reference so the right replacement can be identified.
Questions
How do I choose the length?
Measure the tank's internal height from the mounting face to the bottom and choose the nearest gauge length.
