Its tight
Good Golly Miss Molly, its a temperature sender for my truck. Its a 94 truck so I think the correct colloquialism is "its tight man". So there's that.

Fit perfectly and as importantly read accurately. Temp on dash matched the infrared gun measurement. What you would expect for the price and OE quality.

Not sure if my issue was caused by the sensor or the thermostat. So I replaced both. All good now.
