80 series fuel gauge

I would say that maybe the fuel guage in the big tank may not work until it starts to get low. I had an FJ45 with a big tank. The fuel guage did not give an accurate reading, accept to let me know when I was about to run out.

Mine does the same. Gauge only starts working when you get down to the bottom half of the tank. You should see it starting to move within the next couple of hundred km. Enjoy the feeling - it seems to drop down fast when it does start moving.

mine does the same too. Gauge only moves when there's 55 litres left.

I have the same thing, I am guessing it is because when the tank was fitted they have just refitted the same 70L gauge which does not have sufficient travel for the 190l tank? not sure as it was on the car when I bought it.

I have been throwing around wild theories of changing the intenal mechanisms, I am not sure what type the sensor is though. if it is a swing arm then lengthening the arm should solve the problem, so far it has not bothered me enough to get too carried away.

because of the limited travel it depends on how it is calibrated as to how the gauge will read then, I know from driving that I get approx 200km's before the gauge moves, 600kms over the full to empty then another 400kms after it hits empty, so I set my trip clock when I fill up and change tanks when I hit 1200kms. This allows for a fair bit of offroad work in this figure.

just remember to close your eyes when paying for a full tank :-) The much loved shop-a-dockets only cover the first 150l

Hey guys, that doesn't happen with 'Yotas. No 'me too' here....
