fuel sender questions again! (fixed see pics)

~Just for reference, the design of this type of fuel sender is termed a 'dip pipe' most characteristics for these are 90 ohms to 3 ohms.

we get a lot of different type vehicles using this type of sender where space in the tank is limited.

the new design appears to be inductive, and there are little diodes across an electrical trace at set intervals, like a ladder, all the way up.

They're actually reed switches that are actuated by the little magnet in the float. I must admit I don't like the sound of that one with the 2 copper strips - sparks and fuel tanks seem a bit of an iffy combination......
