Sources we could not obtain
- https://com/globalassets/products/residential/portable-generators/owners-manual/gp-series-portable-generator-owners-pdf -- Wrong product: byte-identical (sha256 fdb50c53...) to the GP6500/GP6500E/GP8000E manual; it has no GP5500 specs. The earlier 1 qt / 389 cc / F7TC values were GP6500 values. Replaced by gp-series-owners-pdf (GP5500E, 2025).
