Fuel Tank Warning light on 80Series

Means you probally have water in your fuel system. try changing the fuel filter and bleeding the lines.

At a wild guess, Id say contact toyota ;-)

But which light is it, what color is it, and what does your book say it does?

Hi Matho
The square orange light next to the fuel gauge indicates approx 10 litres of fuel remaining
The fuel light that looks like a radiator is from the fuel filter and indicates that there is water in the fuel filter and needs draining.
There is a drain tap on the bottom of the filter

If you own a petrol cruiser, it means there is a problem with the tank level controls or fuel pump over...to get rid of the warning, pull the wire off the ecu, situated pass rear quarter panel. If it comes back straight away, it is most probably telling you the fuel transfer pump is RS.

I remember once when I had the battery disconected for a lengthy time that when it was reconected the fuel light wouldn't go off ( full tank) Toyota told me to disconect the battery again for a couple of seconds and then re connect.
Problem solved.

Let us know what you find.

Hi Matho, used to own an 80 series petrol. (Great truck, now have a deisel.) Had trouble with fuel warning light too. Turned out we couldn't access our sub-fuel tank to transfer to main tank. Mr Toyota drained both tanks and fitted new pump and sensors. All were a both dirty, and as they are super sensitive, set off the warning light. Wasn't a cheap solution but it had to be done. We are not mechanically minded, that's why we didn't tackle it ourselves. Good luck. John and Sally.
