The air filter housing, located above the fire, was consumed. The unprotected Racors showed no effect whatsoever.
I'm very interested to hear how you dealt with the fire. I once came very close to a similar fire. The gasket on the gen set lube oil filter developed an pin hole leak. It was spraying a fine mist of lube oil onto the main engine turbo. Fortunately there was an insulation blanket on the turbo which had not yet gotten saturated to the point the oil reached the turbo. The odor of hot oil got me to take a look and deal with the problem before ignition.
Some things are worth doing simply because they are worth doing.
