After I fill up with gas, my car smells pretty heavily. I've got the windows open always, so it might be from outside, but I've been very careful not to spill, etc...Could this be something along the lines of leaky tank or (gasp) split fuel lines? I checked out the fuel lines over the manifold and they look good. There's one hose that is most definately split to the weave, but I don't know what it goes to. I'll try and get a pic...

I remember reading about this before I think it was a vent from the filler.

I had a pickup that would leak gas on a hot day if I filled it "all the way" the gas would got hot, expand and leak some until I ran it down a bit.

There have been several hood fires lately from cracked lines, I'd give them serious thought.

Here's a pic of that hose...Doesn't seem fuel related, but it never hurts to ask:

The early 944's with the 16 gallon gas tank has the old style non pressurized fuel vent lines coming off of the top of the tank and to the filler pipe.

The larger vent hose will crack and leak right where the line exits from under the sheet metal and bends to match the angle of the filler pipe.

There are two solutions. Drop the tank and replace the old style hose with newer hose as the post 85.5's use or bend a piece of tubing the same angle as between the tank and filler pipe, cut the existing hose at the bend, insert and clamp the steel tubing into the old hose.

You have to pull the side carpet off, prop up the trim panel around the window, remove the insulation and take the screws and nuts off of the cover to get to it. Get a package of 3-M black sealing putty to fill in the places were the old putty will come off. This cover must have a good seal or you will get exhaust fumes in the car.

Think I have a picture of both tanks out of the car.

Early 16 gallon tank - Metal


Late 21 gallon tank - Plastic

The picture shows the coolant hose /to/from the heater core.

I thought heater hose too, but is that a metal fitting on the engine side?

Looks like A/C line to me. The heater hose would be lower than the cam cover at this point. And they don't have crimped metal fittings.

Crap. Repla$e the what? Thanks, SoCal, is there a way to see this from under the car or is it on the "top?" This sounds like a job for a mechanic...

Any further IDs on the hose? If it's AC, it don't matter, 'cause it be long broke anyway. If it's coolant, some tape will surely cure all.

My Infinitely Wise Father offered this as an explanation:

[quote]I think I know what's going on. First of all, with that car, when the gas
pump shuts off auto, it's full. If you "top it off" and fill it up into the
neck, it will smell of gas. It is worse in hot weather because the fuel
comes out of the underground tank at a much lower temp than where it is
going. You fill it to the top and it expands and the fuel has no where to
go so I suspect it floods the charcol canaster which is inside the LF
fender under the antena. Yours is slightly damaged and reinforced with duct
tape. A new canaster is like uh...more than I wanted to spend several years
ago. My solution is don't top it off ever - even in winter. Fill it before
you use it rather than when you are done. If it's like 100 degrees outside,
consider not filling it at all - stop at 3/4.<hr></blockquote>

I'm gonna take a look...I remember the day that cannister fell and was just rubbing against my wheel...
