Nivex Petrol gauge help request

Leo 'Lancia' Schildkamp writes: "I would like to ask a question the international community of classic car afficionado's. Amongst all these people, might there be anyone who has a brochure or a manual of a Nivex tank level meter to share on these pages? Or maybe someone who can explain to me how this works and what I'm missing? What I do know: the pump has a valve with two exits. One of them is connected to the meter and the other one goes to the fueltank. And that's where my problem starts."

Editor: Correct Leo, that's where the problem starts. What you're missing is the vacuum mebrane discussed here a few years ago. A good explanation of the Nivex system is to be found here at CarCrank.org. Still we hope for Leo (and also for ourselves, as we have the same set-up in our Amilcar) to find a manual or detailed tech description. 'Le Nivex' is also seen on Alfa Romeo, Bugatti, Delage, Hispano Suiza and more.
