Transfer betwen fuel tanks (1 Viewer)

Hello,

I am curious about the part that actually switchs between the fuel tanks, after hitting the SUB Switch.
And location.

Thanks

It is a electric pump, it is inside the aux tank, it pumps the fuel from the aux tank to the main tank.

Thanks..
How does that work?
The aux pump is looks independent when I removed it from the aux tank.

In that case, the main pump is always running...???!

May be there is a check valve....and the fuel goes directly from aux to engin..

I think it’s fully redundant system!?

Yes, OEM set-up is redundant system.

Is yours gasoline? If it is, then yes it is redundant. Fuel pumps in each tank.

Yes, Petrol.
I am still curious about the part that actually switchs between the tanks, when you hit the SUB switch.

I'm pretty sure it changes the signals to the fuel pumps. So when you press the SUB switch it turns on the sub tank fuel pump and turns off the main tank fuel pump.
