Fire in the hole...
 
Actually in the airbox, vertical induction FI with no drain holes for excess fuel to escape. I saw another similar situation that caused a lot more damage, this one escaped with some minor air cleaner and fiberglass damage.

Airbox's (both carb and FI) need drain holes, I put 3 in, one in front and one behind the air cleaner for rain and such and another in the center of the filter to drain excess fuel that may accumulate there (tail draggers get the hole towards the rear).

This one will get the standard metal plate in the bottom repair as the fiberglass is also worn thru in a couple spots.

And this exact scenario was described in Vic Syracuse's seminar which I just watched.

Ya beat me to it. :) Great presentation by Vic, for sure. A variety of other important things to watch out for in maintenance and inspections that he points out, and it's not only loose jam nuts!

.032" works pretty good for the bottom plate.

And what size drain holes?

Thanks,
Dave

Do you bond it inside the airbox with proseal, or is there a better way?

Yes I use proseal to bond it. It's captured by the filter so no real worry about it coming loose.

What caused the fire?

This is what the sniffle valve is for in horizontal induction sumps.

I sometimes worry that for a taildragger, the sniffle valve is not quite in the best location. But it can not accumulate very much.
