It usually isn't sealed.  The float has a pin which comes thru
a hole in the cap, this is where the foam usually comes out.

Foaming can mean a couple of things:

1. The pump is sucking air in somewhere.

2. The pump is dying.

It is no surprise that the pump starts leaking after foaming at
the resevoir - either it was dying to start with or (less likely)
the lack of lubrication caused by sucking air has killed it.

I doubt that pressure was increased...
