Has finished the installation sub tank to my VZJ95. Now I have 90+70 liters and can go more then 1000km on one filling. It is 90% assembled of Toyota factory components except wiring. The tank itself is from Hilux Surf 185, two way fuel tank inlet is stock, main valve is from 100 series (modified), valve bracket is stock from diesel version (modified), main fuel tube is stock, the switch is from rear heater, The switcher operates two 5contact relays (one switches fuel senders and the other is for fuel pumps). The original connection scheme without return valve makes these two tanks semi independent (the return comes only to the main tank, but each tank has its own pump).
