...There is and has been a raw gas smell with my 94 Explorer (113k miles)
for a few months-I figure it may be related to the fume canister and
solenoid system, but am not sure.??
After doing more testing I noticed a tiny amount of liquid when I removed
the vacuum line attached to the fuel pressure regulator and I'm am now
wondering it it is the issue instead of the fume recylcer???
Thoughts???
THANKS!!

You're exactly right. Replace the fuel pressure regulator. It's pretty
common for the diaphragm to start to leak and allow fuel into the vacuum
side of the valve which dumps directly into the upper intake.
