Prado 2008 120 diesel let me down for the first time.
Brr Brrrrr Brrrrrrrr Brrrrrrrrrrrrrrrrrrrrr....
mmmm It sounded and acted like it ran out of fuel?..... but there is still 1/2 of the last tank showing on the gauge.
Once we added 10 litres of diesel, away she went without a problem. Went straight to nearest servo and filled up with 140 litres which is what I would have expected based on fuel gauge indication.
So I referenced this site to look for the cause but nothing seemed exactly like this.
Several similar reactions to running out of fuel, but none of the explanations seemed to match or fill me with confidence.
Only one thing for it - out comes the tank and pump.
I was also encouraged to remove the unit by others comments on Toyota's lack of knowledge on the whole fuel setup, combine with prices quoted for replacement unit ($1000) plus lab.
Using Whitey1 post at http://www.pradopoint.com/showthread...l-to-clean-out, I have added some extra pictures, observations and thoughts.
The only way for fuel to access the fuel pump once the tank is half empty (below the top of the pump housing) is through a small swing valve at the bottom of the housing. It must have been blocked. This is the only explanation as to why it chose to stop at this 1/2 way point and go again with 10 litres added.
The interesting things found were:
1. Black sludge film all over and in base of unit (unfortunately no pic taken). Similar to sludge in secondary fuel filter replaced 6 months ago. (picture of this added as a fyi) Inside of the tank was really clean (after 220,000km).
2. Mesh sieves (2) in unit - both heavily caked with sludge. One for the pump suction and one for??
3. Found an amazing number of rocks trapped between guard and fuel tank (plus some behind the guard on the side). This is something to watch out for as the tank is poly, although this may help it not being holed due to flexibility. (Thanks to living alongside Oodnadatta, Birdsville and Borefield tracks).
Now all cleaned out and back together and waiting for the crucial 1/2 way point on final tank to be reached. (Yes, I still carry 20lt just in case, until I have confidence back in 180lt being fully available).
One last thought.
Why do people build fuel tanks and then place the fuel pump inside them?
