You would be better off being slightly proactive on the maintenance of the next spamcan you get into, perhaps asking when they last changed the fuel hoses
I have read some accident reports involving fires and IMHO all were totally preventable.
One horrible one occured on a homebuilt, of a type well known for using rigid ally fuel plumbing under conditions of vibration, and the tube eventually cracks. Certified planes are a lot better built in this respect but if the rubber hoses are 30 years old, or been removed and refitted several times...
