Hmmm - I THINK there's a TSB about this. A clamp or hose that shrinks
too much in extreme cold or something. But maybe for the Imprezas?
Check around at www.cars101.com or call the dealer.

I've had this problem with my '02 Forester when the temps went down towards
0°F. I found two hoses leaking. One was by the fuel filter, near the left
shock tower and the other is was on the (as you face the engine) left front
side of the engine. Both hoses are similar, about 6 inches long with clamps
you can tighten with a screw driver.

i appreciate the information, but how did you spot the leak, liquid
fuel spurting out, or by smell?

The first time I followed the easy to see fuel lines and there were two
rubber hoses that coupled steel tubing together. I tightened the clamps on
them and it solved the problem. A few months later I some service done to
replace the brake pads and a few hoses. The next time it got below freezing
I noticed gas odor. Both of the replacement hoses were leaking and I could
see fuel residue by both. Tightening them fixed the problem again. I fixed
them in November or December and we've gone through a winter of almost
daily near zero temps in Jan and Feb, so I think some muscle on those four
clamps is the fix for cold weather fuel odors. This doesn't rule out other
points in the fuel system, but the two hoses are easy to see and it's easy
to tighten the four clamps. If that fixes the problem you're done in a few
minutes. If that doesn't fix the problem, you'll need to go to a garage that
has a hydrocarbon sniffer (used to find refrigerant and fuel leaks), or
crawl around under the car looking for other places the fuel lines are
connected. I think another source of gas odors might be the charcoal
canister, but the high pressure side of the system from the fuel pump to the
injectors is where I looked.

Is this driver's side, nearer the firewall than the strut tower? I
think I tightened this one once this winter. Looks like I have some
fuel hoses to replace too.

Anyone replaced fuel hoses? Is there much to worry about other than
the small amount of gas that'll be in the hose itself?

Passenger's side front, gotcha.
