M101A2 Master Cylinder Cap Gasket

[Rustyshackelford]

Hi There,
I recently bought a M101a2 trailer to compliment my M1009 and I have my first question for the trailer forum. The master cylinder seems to be leaking fluid from the cap threads. It has a small o-ring in there I think someone tried to retrofit but it is the wrong size. Does anyone know where to find it, or can attach a pic of the proper o-ring or gasket?

PS This is the cap with no hose.

I have indeed looked in the TM and searched for the part numbers with no luck.

Thanks in advance for the help.

I think the easiest method would probably be to buy a sheet of gasket material and cut your own. I've never had one that didn't leak a little or come across a decent gasket.
