Thanks for your help, David. And also for bearing with me as a lot of this is new to me!
Update: As you suggested, I'm trying to figure out which is the fuel return line, and which is the hose from the canister – so I can figure out if they are connected to the wrong bits on the carbon canister.
- How do I know which is which? At the moment, the line furthest from the engine is running to the 'From fuel tank' on the canister. (page 69 Haynes)

ALSO:
- Having a closer look – it appears my vac purge control line is not connected. As I understand it – this is due to the installation of the webers. So that shouldn't be a problem. The webers were installed by a datsun specialist who was recommended to me so he would have done that right.
- Also the purge control valve diaphragm doesn't seal properly. (Haynes Manual page 68). As this line isn't connected anyway (due to webers) I guess this doesn't matter? Not sure about this.
- Also I stress, this happened after I essentially over-filled the car and then parked it facing DOWN a hill so the expansion tank may have dripped fuel to the canister and out of the broken diaphragm? The car runs great performance wise. Does that make logical sense to someone that actually knows what they are talking about??
Thanks guys – always stoked by the time people are willing to give to respond to questions like this
