This demonstration guide answers one field question about fuel transferred near a hot muffler. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with cool-down time before refuel. That reading separates fuel transferred near a hot muffler from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the fuel can spout as the primary path. If it is in spec, do not replace the fuel can spout just to complete a parts list.
Repair the failed system
The usual correction is the fuel can spout, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about fuel transferred near a hot muffler.
Stop before you make it worse
Do not refueling a running generator because "it cannot be shut down". That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the fuel can spout is corrected, convert the visit to a broader diagnosis rather than stacking parts.
