The tank sending unit is held in by a plastic ring that screws onto the top of the tank. See if it has unscrewed for some reason. It is sealed by a big O-ring.

There are also a couple of vent hoses that go into the fuel sending unit.

The sending unit does seem kinda loose, is there any for sure way to see exactly where it is leaking? I have tightened every clamp so they are fine.

Have someone pressure the tank and watch for fuel coming out.

If no fuel comes out feel around it for air coming out.

About the most you need is a couple of psi in the tank.
