My 2002 td prado gxl on thre separate occassions has, when cruising on the highway, the fuel gauge has dropped at least half a tank in the space of about 20 ks. The gauge has stayed there untill the next day or when fuel is added then it returnes to the corect level. Has anyone had this problem or know the cause of the problem, otherwise the prado is excellent, after 5 years with an 80 series diesel the extra bit of go is very welcome.

I have had mine for 40K and never had the problem. Prior to that I had petrol Prado's and never had the problem on them. When it dropps to half full or is that half empty how much fuel is in the tank? If it is reday correct at half full maybe the sender unit is sticking or you have an intermittant electrical fault.

DJR,

Which tank are we talking about? Sub or main?

David's suggestion of a sticking sender is most likely. It can result from a ding to the bottom of the subtanks causing the baffle to touch the float. Got any good dings in your subtank?

Otherwise, it sounds like the tank needs to be emptied, dropped and the sender removed.

Like you, I replaced my earlier diesel Landcruisers with the Prado diesel, done heaps of trips and its a much better vehicle. The Prado email group is at

Thanks for your tip. no there is no ding in the tank. It only seems to be on the main tank.If it was a stuck sender wouldn't it stay on the same reading before it dropped, but thisis not the case it is reading correct till it takes a sudden dive,always travelling at highway speeds and wont read true till at least the next day or I add fuel

Djr,

Got me stumped. Off to the dealer I guess and get it fixed under warranty. They'll probably replace the sender.
