"O" ring sizes on master cylinder sensor

[DELL82]

I need to replace the level sensor "O" rings on both master cylinders.

This is the Brake fluid level sensor that is mounted in the master cylinder bowls.
Bike is an XJ1100J Maxim.
This is a small "O" Ring about 3/8" diameter and needs to be Brake fluid safe IE: silicone, EPDM, Ethylene Propylene etc.
So far I think it is an -011 size but not sure as that dash number is for English not metric. This part is not listed on the parts diagram.
Also need size for #51 (on micro fish)fork tube AIR SLEEVE "O" ring size, 4 needed. This is the air inlet sleeve around the fork tubes at the top.
Thanks for all the help.

Hi Dell,
I dunno but perhaps if you take your dead o-rings to a hydraulics repair shop they will be able to identify them for you. Or measure the groove width and the OD they fit in and take that information to them.
Houston is oil country, right? Gotta be full of hydraulics shops?
