Am wondering if the sending unit resistance in the 240, 740 and 940 are all the same. If so, will a 47 ohm resistor provide something less that a full but more than a half tank indication.<p>In addition, is the GR-W wire the correct wire to ground thru the 47 ohmer?<p>Joe <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">
