Optical encoder sensor o-ring part number

[dieselolds]

Hey guys.Just posting this in case someone here needs the part number for the optical sensor o-ring that commonly leaks.It’s stanadyne 30098.

is this the round oring on the sensor or the squarish one that goes on the top cover of the IP? I have heard that top cover oring is hard to come by.

As far as I know the 30098 is the o-ring that commonly leaks under the snap ring area upon the optic sensor.I don’t know if that one is square cut or just a odd size o-ring.
