Prado150 Fuel Light Flashing

[jonog Lurker Find all posts View Profile Close jonog]

The fuel light on my 2011 Prado 150 GXL is flashing. The owners manual suggests that this means "Vehicles with subtank have 22l of fuel or less remaining". The tank was over half full, but the gauge reads about 1/4 full. Something doesn't seem to add up. Does anyone have any ideas. Would there be 2 fuels sensors on this model?

If it is just the fuel light flashing then I'd get fuel asap. If it is a picture of a fuel bowser with some dots below it then there are other issues.
I had exactly the same light and ran out of diesel. The result for me was that the rear tank was full and the front tank was bone dry. Caused by no fuel being transferred from the rear to the front tank.
I was showing about 1/3 tank on the gauge.
Here is my thread on it:

Thanks Jimmy. That makes sense as Toyota have just pulled the fuel tank out about a week ago because we had contaminated fuel. I'm thinking that the hoses or wires have not been hooked back up correctly....

Did you end up working out what all of the 5 hoses were for?

I have it written down somewhere but 1 is a fast fill breather (biggest one), one is a tank breather (smallest one), 1 is a fuel pickup and 2 (what i call) the loop of pointlessness. I mixed up one of my loop of pointlessness hoses with the fuel pickup because they are right next to each other. By memory it goes, from left to right, 10mm, 10mm, 15mm, 10mm, 6mm. I mixed up the 2 10mm ones. If that's your problem there is a way to right it without dropping the tank. But since they hooked it up wrong they should be paying. There is no mechanical pump between the two tanks so that would not cause an issue

Below is the response that I received from the dealer when I queried it.

"Fuel is pumped from rear tank until level sender in the rear tank registers approximately ¼ of fuel in tank, then sends signal to computer to pump from main tank, because the fuel sender gauge is open circuit it is no longer sending signal to computer so fuel does not get pumped from main tank."

This explanation does not really seem to make sense, but I don't have a schematic for the fuel system wiring.... They are trying to say that the engine gets it's fuel from either the main or reserve tank? I was under the assumption that the engine sourced the fuel from one tank, and the other tank simply syphoned into it?

Is anyone able to offer any advice.

I don't mind paying to have my car repaired, but suspect that I have been dudded in this instance....
