My 1998 Subaru Legacy was smelling gas and I noticed gas spots on the ground. I took it to my mechanic and he said it appears to be leaking above the tank, apparently a common spot on Subarus. Anyone familiar with leaks up in that area? It seemed to got worse after I put 3/4th's tank full gas in a few days ago. Anyways, I am leaning strongly to replacing the car very shortly as it has 237,000 miles on it with rust issues on the rockers. I was planning to replace the car in May, and I am wondering if this kind of leak can last another 10-12 weeks or should I bite the bullet and replace it as early as this weekend. I suspect it has been leaking some as far back as last fall, as I smelled some gas then, but couldn't locate it and the real cold hit and smell went away. Any suggestions appreciated. Not sure keeping tank low on gas will help, but I am not familiar how gas lines run int hat area. I fix the problem (they estimate several hundred bucks as tank needs to be lowered) , but I don't want to put any more money in the car.
