I would contact Van's and get their advice. I had a similar problem 20 years ago when a tank rivet fractured and developed into a fuel leak in the cockpit - fortunately on the ground. Scary enough though, so I had an aluminum-welding fuel tank expert build me a new tank with an internal bladder and reinforced welds - gas has to get through four layers before it can get to me in the cockpit now. Unfortunately, my expert passed away several years ago.
While you're at it - and hopefully you have already done this - go on Van's website and go to the "Support" and then the "Safety & Service Info" for the RV-3. There are quite a few Service Bulletins for the -3 that are important to know about and comply with.

Good luck!

I purchased my first -3 this week and had it delivered yesterday. I noticed that the 25 gallon fuselage tank has interior baffles that seem to be loose or something. Rocking the plane back and forth, it sounds like the baffles are clanking around inside. Does that sound familiar to anyone with a fuselage tank?

Have someone rock the AC while you look through the fill hole with a small flashlight (don't drop the flashlight in)
Should be able to see the baffle and movement if loose.
Also, sound could be the sender wire and float if using mechanical gauge.
If loose, tricky but you could rivet with blind rivets and seal over.
