Condition
New, never installed and never fueled. Factory emission label intact. Tanks were stored outdoors on the original pallets, so expect light dust and minor handling marks. Serial numbers vary by tank.
Important Fitment Note
This tank is NOT universal. It is an OEM under-chassis fuel tank, so mounting straps, frame spacing, fill and vent routing and the generator or fuel station plumbing all have to match. Compare your existing tank and the photos before ordering, and confirm which certification your build requires. This CARB/EPA version is certified for all 50 states, including California.
Shipping
These ship by freight or are available for local pickup in Jefferson, Ohio. Add the tank to your cart and request a freight quote, or call (440) 209-2866. Several tanks can go on one pallet, which is much cheaper per tank for dealers and shops.
