the engine with efi i was mucking with turned out to be dead so looking at a carb engine and in the process of reseting the changes I made to the series2 body I didnt take careful note of the tubes in and out of the change over valve in the boot.

this image i have labelled A, B and C

to these connectors which fuel lines are connected?

(.e. tank1, tank2 and pump/engine or in/in/out whatever)

 

All I got is this.



Looks like "B" is TO the pump, and "A" and "C" are the connections from the tanks.

 

I suspect that is correct, never hurts to check, i really should have made notes first for such a simple thing.. oh well.
