My petrol sender unit is on the fritz.
It flashes horizontal bars on teh dash board.
When I remove it I can see the resistanece changing as I move the float unit (Manually up and down the unit.
However when it is in the car doesnt work.
I managed to get another working sender and on installing that one the petrol guage worked fine.
Looking for a working unit that someone might have in the back of their garage before I have to empty my piggybank out to the Renault stealers.

Any help appreciated.
