Being an oversized tank if it was longer than the stock tank then you would be able to put more fuel in it before the gauge registers. Do you have a vehicle with the stock tank you can use the sender in for comparison?
You mean swap the gauge? Yeah, my truck has a stock style Blazer tank and sender w/ stock cluster. May have to do some comparison readings between the two trucks with the DMM then possibly swap clusters if I have to. Was hoping someone had seen a failure like this before, to save me the trouble of swapping everything around...

I'm still thinking 42 ohms at the fuse box should equate to somewhere around the halfway mark on the gauge?
