Replaces the factory main tank; uses the original pump and sender.

## Selected configuration

- Part/component: FK-LC250-MAIN-TANK
- Configuration: SLEE listed 29-gallon LC250 replacement system
- Listed parts: $1,995.00 USD / selected configuration
- Source checked: October 25, 2026 (Pacific)
- Fitment: SLEE LC250 2024–2027 application; confirm exact US hybrid/VIN and revision
- Product mass: Product weight unverified
- Net vehicle addition: Net addition unverified
- Weight basis: Installed net change requires all mounting hardware and factory parts removed; shipping mass is not installed mass.
- Professional install: 4–5 hr; published
- Basis: 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.
- Contents: Replacement main tank, brackets and hardware per SLEE; reuses factory fuel pump, sender and fill tube.
- Critical specifications: 29 US gal total · ≈11.1 gal extra versus 17.9 gal baseline · spare retained per SLEE · integrated skid.
- 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.

## Prerequisites

- Selected product / listed contents (included): Replacement main tank, brackets and hardware per SLEE; reuses factory fuel pump, sender and fill tube.
- Loaded fuel and spring planning (check): 11.1 US gal adds approximately 66.6 lb of gasoline at full capacity, before dry tank/container and mounting weight. Review full and empty load cases; do not choose constant-load springs solely for occasionally carried fuel.
- Product revision and weight conflict (conflict): SLEE lists 81 lb and 4–5 hours; FK 110L page lists 24 kg and 2–3 hours. Confirm exact kit revision and installed net weight before purchase.
- California eligibility (check): No exact California approval was verified. Obtain documentation for the exact US hybrid application.
- Availability and installation scope (quote): SLEE currently lists out of stock. Quote tank draining/removal, pump/sender transfer, mounting and leak/gauge checks. Verify OEM tank capacity and any retained skid/aux-tank compatibility.
- Combining main and auxiliary tanks (check): Do not assume a replacement main tank works with a separate auxiliary system. Confirm filler, transfer, EVAP, skid and mounting compatibility as one complete system.
- Installation / compatibility notes (check): 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.
- Installed net weight (check): Product weight or factory equipment removed is not fully verified. Do not use shipping weight or assume zero additional load.
