Dry it off with a towel and then use coloured loo paper to find the leak if it's small. Once you know what's leaking you can get advice on how to fix it!

If vision is impaired, wipe around the top and bowl of the Auto air vent with soft bog paper ( the best value comes fom Lidl. Lidl's best quality - lovelly on the more delicate rectum) Then somewhat later check out for wetness. Same goes for the pump joints.
If the Auto is leaking best replaced rather than removal and cleaning.
The pump joints may just need tightening rather than remaking
Its good to have one of those little round mirrors on a wire stick often available at auto parts.

As ChrisR states coloured bog paper is even better
