Discussion:
Can anyone tell me what this fuel symbol means?

I'm working on a Toyota diesel 8FDU30 with a 1ZS motor and there is a red fuel light on with a bar under it. I think it's the low fuel light but it has a fuel gauge that works fine. I also read somewhere it could be a water in the filter light but I drained the filter and the light is still on. I haven't changed the filter or removed the battery cable yet.

Yes that is the "Sedimenter fuel filter warning light"

Phenomenon:
Sedimenter fuel filter warning lamp turns on.

Probable causes:
* Fuel filter clogging
* Puddle in sedimenter
* Harness defect
* Fuel hose defect
* Clogging switch defect
* Sedi-menter switch defect
* Engine control failure
