Product mass: Product weight unverified
Net added vehicle weight: Net addition unverified
Weight basis: Factory components removed, mounts and hardware must be reconciled. Shipping mass is not substituted for installed mass.
Professional installation: 4–5 hr · supplier published
Installation scope: tank mounting, filler/transfer plumbing, protected pump wiring and leak/function checks, or pack mounting to an existing rated surface. Read the exact product scope; container-only setup excludes mount work.
Fitment / supporting work: SLEE lists this option out of stock at $1,995, 4–5 installation hours and 81 lb item weight. FK’s 110L page instead lists 24 kg and 2–3 hours; exact revision equivalence is unconfirmed, so dry weight stays pending and prices are not combined as identical offers. Added gasoline is calculated above a 17.9-gallon stock baseline, not all 29 gallons. Manufacturer fitment-year wording also needs exact VIN confirmation.
