Diesel Install kits are optionally available. Not intended to be used for gasoline. Made in the U.S.A.

* LEAD TIME NOTES: Due to large amounts of orders, manufacturing delays and part shortages, lead times can vary between 8-10 weeks until shipment for the low price of the tank that you see above. TankAndBarrel.com offers our customers the LOWEST price on this tank because our products come directly from RDS.

If you are unable to wait 8-10 weeks, it is possible we can get this tank immediately via one of our wholesale partners. The downside is that this will raise the price of the tank slightly. Please contact us and we can check availability of this tank from our wholesale partners and provide you with a new price to ship immediately if you are unable to wait the 8-10 week lead time. Thank you!

NOTE: For safety reasons, the filler neck of these tanks prevents them from being overfilled. Actual usable tank capacity is about 95% of the total advertised gallons.
