N/A PCP Hand Pump Damage my gun?

The gauge on my pcp hand pump had a liquid in it when I bought it. I just noticed it no longer does and the area around the gauge is oily. Is it possible for the liquid to pass into the rifle when I'm pumping air into it? I'm concerned the liquid might have gotten into the rifle. So far the rifle seems to be operating fine. Thoughts?

Glycerin leaks at gage are common unlikely it made it anywhere past the floor
