Description
18 more gallons under a 3rd gen Tundra
Built from thicker 3mm 5052 aluminum in hammer finish powder coat, and it bolts into existing frame locations so there is almost no modification to the truck itself. KDSS, factory air ride and your Class 4 receiver hitch all stay.
Read this before you order
This tank requires the rearmost tailpipe to come off. You either cut the factory pipe down or replace it with an aftermarket turndown.
We build one for this exact truck. Our 2022+ Toyota Tundra High-Clearance Muffler Replacement Pipe is made in house in 304 stainless and solves this in one part instead of a hacksaw and a prayer. Add it to your order and you have the whole job covered, from one shop, with one person to call if something does not line up. No other retailer selling this tank can say that.
One fill, both tanks
Plumbs into the factory filler neck so both tanks fill together. A programmable transfer switch and fuel level gauge move fuel forward and monitor it from the cab.
