I've read over lots of the forums here, and I think I have a good idea where I need to look/inspect. Hoping someone can look at these symptoms and maybe say "hey that is...."
-Intermittent Smell inside and outside of raw gas, usually when hot, but sometimes when cold. Usually outside only, but now inside, and most recently in the trunk.
-Spitting raw fuel (very little, but definitely raw fuel) out the tailpipe when engine cold ***EDIT there was such a strong smell coming from the rear that I convinced myself it was fuel, when it was in fact water.
-Starts have become a little harder occasionally when cold or hot? Fuel pump going? Sounds very similar to when the car struggled to hot start before switching to battery cables...like hesitates, clunks, then goes.
Things I've done:
Inspect under gas tank/filler and wasn't able to notice obvious fuel, but did see some rust near filler (photo below)
Lift up back seat and inspect/smell around sender and didn't smell/see fuel too obviously until my face was directly in front of it, then got a bit of gas smell (should I change this seal either way?)
Fuel rail or something similar?
I know, based on the vintage, and condition of the car it is likely not one thing. But to deal primarily with the fuel smell I'm hoping someone might have a Eureka based on this info.
