Hello,
I have just bought a second hand 2003 Landcruiser 100 4.7L V8 Petrol and I have a question regarding the main / sub tank.
The question is - Is the correct operation of the main / sub tank as follows or do I have a problem.
If the main tank is selected (no sub indicator displayed) The sub tank is used first and then the main tank.
If the sub tank is selected (sub indicator displayed) The sub tank is used first and then the main tank.
I think that when I select the main tank - the main tank should be used and the sub tank should only be used if selected.
Regards
Carl

Dunno with the V8's
diesels DEFINATLY use the tanks as selected IE:
subtank (light on) fuel goes to motor AND returns to sub tank,
vice versa for main(light off).
Fuel gauge will adjust to what ever is in relevant tank.
7# petrols that have 4.5l motor have the fuel cross-over (like gu) because they have a high pressure pump in the tank ,maybe petrol 100's same?
If you are having difficulty working out whats going with yours there maybe solenoid stuck shut/partially shut giving you readings
