This is an 18-inch, 5-wire overfill detection probe used on petroleum tank trailers.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It mounts in the tank and uses an optical sensor to detect when the liquid level reaches the probe tip, sending a signal to automatically shut off the loading equipment. You would replace this probe when the existing one is damaged, corroded, or no longer reliably prevents overfills. It fits standard 5-wire API optic sockets commonly found on fuel delivery trucks and large tankers.
