Subaru has skirted around getting this fixed on early 2000’s where it is prevelant. I believe the amount of fuel leaked is negligible and a bit of gas is leaking. Maybe every Subaru owner should complain to NHSTA and get something going and reimbursement for back repairs.
I know Subaru WRX owners for 2002 only (they fixed in 2003-present) had this very problem. It was around a $600+ repair and was due to the routing of fuel lines near heat. Subaru was covering it for a while but now that has passed.
