I checked the schematic the other day and noticed that it didn't seem like it was on there. It was mounted somewhere near the tank gauge but none of my photos during disassembly caught it apparently .I'm not sure that is part of a 2002 Silver B. I've never seen anything like that before.
Here is the schematic for a 2003. I think the 03 and 02 are very much the same.

In the thread linked below are some pics of a 2002 Silver B that I picked up free and I still have. It didn't have that part. I also picked up a 2002 Gold B and it didn't have that part either, nor did my 2000.I checked the schematic the other day and noticed that it didn't seem like it was on there. It was mounted somewhere near the tank gauge but none of my photos during disassembly caught it apparently .
Oh well. Will keep it in the junk drawer in case I ever solve it.
