For other 90 series owners particularly - but perhaps applies to other ageing vehicles. Be aware of potential fuel tank problem caused by wear.
Severe sustained corrugations on last trip and vehicle age (20 years) led to hole being worn through the Prado 3.4 petrol sub-tank (the forward one). The hole caused by long term rubbing of one of the steel belts suspending the tank under the car. These belts are isolated from directly contacting the tank by formed rubber strips. But when the strips themselves wear through or are dislodged, metal against metal produces a hole.
Fortunately the older Prados came with pumps in both tanks. Failure in one tank still allowed the other to supply fuel. Upon discovering the leak 300km from nearest petrol station, I was able to drain the sub-tank (by bucket), into a spare jerry can, fill the main tank, and continue the trip with just the one 90lt tank.
I've now installed extra rubber glued to the tank and hope that's the end of that problem.
If you smell fuel, be concerned.
Cheers
Chris
