Autococker Cupseal Question

Okay, I have a slight leak coming from my recently built Sniper/Pump Autococker. It is within the valve area, so I think it is the cupseal (being a former VM owner, I know what a cupseal leak sounds like). I have never replaced a 'Cocker cupseal, so I need to know if the whole cupseal and pin need to be replaced or if just the seal can be replaced. Any helpful tips would be appreciated.

I assume that you have a valve tool in order to remove the jam nut and get the valve out.

When you do, also check the oring on the front of the valve itself. If that is damaged, that will also lead to the same kind of leak as a bad cup seal.

Just another possibililty to check for.

If the leak dramatically changes depending on the position of the bolt, it's probably the cup seal. It could be the valve oring, but it's not as likely to be as big a leak(unless you like, forgot it entirely).
