This demonstration guide answers one field question about cans that outlast the fuel inside them. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with purchase date versus a 30-day use window. That reading separates cans that outlast the fuel inside them from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the fuel can as the primary path. If it is in spec, do not replace the fuel can just to complete a parts list.
Repair the failed system
The usual correction is the fuel can, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about cans that outlast the fuel inside them.
Stop before you make it worse
Do not keeping a vented can in a hot truck bed all summer. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the fuel can is corrected, convert the visit to a broader diagnosis rather than stacking parts.
