Upgrade your diesel-powered adventure vehicle with the S&B 40 Gallon Fuel Tank, designed specifically for 2019-2024 Winnebago Revel (4WD chassis), 2022-2023 Entegra Launch, and more. This high-capacity tank replaces the OEM 24-gallon tank, allowing you to extend your travel range and minimize refueling stops.

Features

• Plug and Play Installation: The S&B tank includes all necessary components for a straightforward installation. It mounts in the stock location using included straps and occupies space forward (11.2 inches) and rearward (5.2 inches) of the original tank, ensuring a seamless fit without modifications.

• Accurate Fuel Gauge Functionality: Enjoy increased fuel capacity without sacrificing gauge accuracy. The fuel gauge will read full for the first 5-7 gallons before moving normally. Keep in mind that the Distance to Empty will still be calculated based on the stock 24-gallon capacity. For example, with a full 40-gallon tank and 20 MPG, you can expect approximately 800 miles to empty, although your vehicle's gauge may indicate only 480 miles.

• Built to Last: Constructed from durable ¼” thick crosslink polyethylene, the S&B tank is designed for longevity and reliability. Plus, it’s backed by a lifetime warranty, providing you with peace of mind on all your journeys.

On S&B and OEM diesel fuel tanks, there are one or more rollover valves. The rollover valve uses a float/weight to close the valve when the float is immersed in fuel. This prevents fuel leakage in the event of a rollover. Gravity feed tanks or electronically controlled feed tanks can overfill the S&B or OEM tank. If/when the tank is overfilled, the rollover valves will prematurely close. Without the required vapor space in the tank, this violates the “overfill restriction” requirement of 49 CFR 393.67(12)(i). An overfilled tank can lead to a pressurized fuel tank, leaking, and tank failure. Therefore, the use of a gravity feed tank or electronically controlled transfer tanks (that allow the S&B tank to overfill) in conjunction with a S&B Tank is dangerous and will void the S&B Tank warranty.
