EFI return line, use emissions return?

67dart273, sweet!

Thanks a bundle for that manual shot! That wasn't to be found in my chilton manual!

At least schematically, that vapour/ liquid separator which it apparently is called, is definitively that tubular thing poking up in to the boot of my car! It's a '71 Swinger GT by the way.

Any brazing or welding on my fuel tank is something I'd go a long way to avoid.

Had a sobering experience weldign a hairline fatigue-crack in a motorcycle fuel tank once.. washed out thoroughly with hot water several times, filled with water, but a very small pocket of air still went BOPP! No damage done, but still..

But if I can weld something through the sender unit flange, I'm OK annyway! :)

If I remember correctly, the hoses for the separator might well connect inside the boot, which is a no-no in terms of hooking up a return-line to the thing. An alternative might be to simply block off one entry to the separator and hook the return line up to the corresponding tube on the fuel tank?? Hmm.. that should work..
