This lessens or “drops” the voltage downstream from the connector, and warmth concentrates at the point exactly where the voltages are distinctive; over the position of optimum resistance.
Lastly, examine the fuel alone. Could it be cloudy or discolored? Pour at the very least a cup of it onto a clear white rag or paper towel and see what it seems like soon after it dries out. Is there an even tan stain or can it be a rainbow of colours?
