If all tank seals were done along with the expansion tank grommets
etc., maybe time has taken it's toll. Like under normal circumstances,
while driving around with a full or near full tank, does fuel splash
up onto the bottom of the seals? If so, does this help keep them from
drying out? OTOH....

Maybe only a partial tank reseal job was done 5 years ago? Like the
filler neck grommet and small pipe grommet weren't replaced? Maybe an
old braided low pressure hose got left in place and is now leaking?

Removing the FR wheel makes it easier to check for signs of leaks at
the grommet where the filler neck small pipe fits. The fill neck
grommet is hidden behind the frame rail, but if it's leaking, you
should see signs of that elsewhere. (image of my leaking fill neck

Since one fuel hose took a disco dive, I'd strongly suggest replacing
all fuel hoses.
