Racor 56140 water in fuel sensor OEM manufacturer overrun.
Internal terminating 220K Ohm resistor across wires John Deere type. These are a previous version before the current version with a convoluted tube lock on the connector. They are identical inside.
They plug in, and thread in the same 1/2-20 thread but do not have their plastic tubing captured with the connector lock. That was an upgrade on the current part. These are production overruns before the new revision.
Manufactured by Entratech Systems.
