Underneath the the rear seat I find two Bosch items. On the right A 204 470 2294 which has two thick wires presumably power supply and two thin presumably level sensor. There are no externally visible pipes on this side. On the left is A 204 470 035 which has two thin wires and two pipes. The wires appear too thin to be power.
How does all this work ? Plainly fuel needs to balance somehow between the tank either side of the transmission tunnel but with no pipes coming off the side with the thicker wires I am puzzled as to what happens.
The tank is currently fairly full so can't remove the pumps to look inside
I am poking about here because engine light is on and I have error code 0290 which points to fuel pump however car seems to run OK. After clearing the code it returns immediately.
