Hello to everyone that has read or responded to this thread. First of all, I'm am not planning on blaming any of the manufacturers of the products that was involve in the fire. But after surveying the damage, the fire was mostly contained on the side of the field box where the gas can and the electric fuel pump was located. (The battery was located at the opposite end of the box.) I am not quite sure what ignited the fire, it could have been the fuel pump or the battery. But what I think might have happened, is that when I hooked up the line from the fuel can to the filling tube on the plane, I didn't disconnect the pressure line from the muffler to the fuel tank. This could have caused pressure buildup in the tank, which would not allow fuel to enter the fuel tank in plane, thus causing the line to blow off at the fuel pump. I just wanted to express my concern for safety so that this doesn't happen to anyone else. I will send pictures and a letter to the manufacturers because I believe that all hose connections containing fuel should have a locking system or a threaded type connection. I am just more thankful that it wasn't more serious than what it was. I wanted to express my concern for everybody to be safe.



I am not quite sure when the fuel line blew off the pump, the fuel started spraying and I don't know if it sprayed on the fuel pump itself or on the battery.

Not dis-connecting the line to the muffler should not have caused any back pressure unless the pressure fitting was blocked somehow. It should have just functioned as a vent. More likely the line just came loose for some reason. Old age, hardening, wrong size or accidental pulling on it too many times. I had an old fueling hose crack on me just this weekend. I was just able to cut off the offending piece and move on fortunately. You weren't that lucky.

one of the few engine designs that you have to disconect vent lines is a ys engine system. they have one way valves to keep fuel tanks pressurized at all times. the hose was probably old and stretched, they lose there ability to stay on after awhile. this is a good thing because when they start getting loose then they should be replaced because of the extra risks of line degradation that cause pin hole leaks.
