I bought some used 2.5x16 3 tube piggybacks and while they were shipping one did not have any pressure in it and leaked oil everywhere. It looks like the end cap on the side of the reservoir that goes into the shock body is the source of the leak. The cap is pushed in more than the other shock that has a bit of pressure still in it. Now is the cause of the leak actually just because of the lack of pressure or do I have a bigger issue? And when I go to top it off with oil do I need to check IFP depth? And if so I can't find the proper depth for a 2.5 bypass with a 14" reservoir. I have searched around but cannot find much info. Thanks.
