928 Fires - List of causes and parts to inspect
It seems our cars are prone to starting on fire due to a number of circumstances. Old brittle fuel lines seem to be the number one cause, automatic transmission fluid another, but I'm sure there are others. Could we get a list of probable causes, specifically those applicable to our cars so owners can create a check list of items to inspect yearly? Dashboard fires (shorting wires but which ones?) seem to be another cause. Any thoughts? Year specific too might help.

Flammable fluids in the car include:
Fuel: Inspect lines regularly, replace all lines at least every 10 years whether or not they 'look' fine. Fuel is under pressure and will spray out, causing a fine mist. the slightest spark will set it off.
PS- fluid: Is actually ATF, which is flammable. Again, any leaks in the system will probably be under pressure and spray out in a fine mist, which is highly flammable. Inspect all lines and make sure you have no leaks.
ATF: If you drive an AT, there is an ATF cooler in the passenger side of the radiator (not sure which years, some have external coolers). The lines run from the trans in the back, along under the car, up over the catalytic converter and forward to the cooler in the radiator, then back (feed and return). ATF is highly flammable and the slightest kink/corrosion in this line should be repaired with new lines immediately.
Charcoal canister 'wye' under passenger fender. If you smell gas, don't start the car, find where it's coming from and fix it.
Fuel smell in rear/leaking fuel when full. If you smell gas, don't start the car, find where it's coming from and fix it.
Electrical issues: I don't think I've read about any electrical fires that didn't have contributing fuel or some fluid added to the fire. Make sure your grounds are good and fuses are the proper rating and you should be fine. Also check for leaks above CE panel because water can leak onto it and short things out.

1) A/C lines when they are running a mix of propellant with the freon (cough) Louie (cough) OCIC (cough). 
2) Fuel soaked cats. If you car is running but all the cylinders are not firing, that fuel has to pool somewhere. (Doesn't seem to be an issue with cars with no cats)
