We can buy almost any wire with this resistance if we are free to pick any size, but only a certain range of sizes is practical. In addition to its conductivity we also need to worry about its corrosion resistance and whether it would form an oxide layer that would insulate it from the float.. It also needs to be solderable. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
