I found a page where they talked about how the 47ohm resistor will only be accurate at full and empty, everywhere else along the scale it won't be accurate. It was something to do with how the sending unit works. I'll see if I can dig it up. DocVette's response is the only one where I've encountered the use of a pot to convert down to the correct ohm range. I'm willing to try his idea out but I'm no electircal guru when it comes to making curcuits or anything like that. When it comes to electrical I'm basically a caveman. I can run wires, crimp connectors, solder connections, and read wiring diagrams...but ask me any specific technical stuff I'll give you the o.O look.

Is this the correct pot that I'll need?

As for wiring it up it should look something like this correct?
