Check your fuel hoses!
After my last fillup I got a gas smell around the back of the car. I crawled underneath to see fuel dripping every 20 seconds or so. This was the culprit, the line that goes from the filter to the hard line on the pressure side.
 Check your lines guys, they're getting pretty old and there are too many stories about burned-down 951's. Everyone changes the lines on the fuel rail pretty religiously, but make sure your lines in the back are good! Of course, I also replaced the filter. WYAIT...

Sound advice guys. I'm planning on the fuel filter soon, anyone have a part number for the hose as well?
edit - the part number for the under hood line would help me out too - I need to do that one at the same time. |

Here's the hose mentioned above: 951.356.047.03
I can't remember the over-the-rail hose numbers... next replacement I'll be doing Rennbay replacements.

This is the damper line on the fuel rail, AKA the biggest fire threat.
944.110.413.02 Its also not a bad idea to replace the feed and return lines for the fuel rail. I would just go with the many aftermarket options available, but only use the kits that use COMPRESSION fittings at the hardlines, Dont use anything that makes you use a fuel injection clamp other than at the regulator (like how it is factory).

Our 924S had the same cracked hose when we pulled it.
On my 951: I'm in the process of switching mine to steel braided AND putting fire sleeve & tape over it. Maybe overkill -- but I'm not taking any chances. mike
