Factory Auxiliary Sub Tank Install

[LandCruiserPhil]

Hello Phil,
can you advice me what fuel hoses should be connected to the dual filler neck? I an installing my sub tank as well but it seems that the filler neck has a diameter of 42.6mm which is an odd size? Did you use the original Toyota fuel hose and if yes what is the part number?
Thanks!
Gilles

The soft flexible hose I used is noted somewhere in my thread.

Hello everyone! i'm doing this project on my rig now and I have a question that i could not find the answer on the form.

Where do you connect the outlet of the sub tank outer fuel pump to the main tank?

for reference, there is an outlet port on the Aux tank, that goes to the input of the aux fuel pump, than where do you connect the outlet of the pump to the main tank?

thanks a bunch!

David

This thread shows how @LandCruiserPhil pumps the fuel from the sub into the breather hose for the main tank.

This thread has a picture of the stock fuel pump bracket which has an extra line for the sub tank. It is my understanding that this fuel pump bracket is no longer available. I sourced a used one from Australia when I did my install.
