S&B 40-Gallon Replacement Fuel Tank for 2018-2019 Winnebago Revel & 2007-2018 Mercedes Sprinter

S&B’s 40-gallon replacement fuel tank is designed to increase fuel capacity for 2018-2019 Winnebago Revel (2017-2018 chassis) and 2007-2018 Mercedes Sprinter 144" & 170" wheelbase vans. This upgrade replaces the factory 24-gallon fuel tank, nearly doubling the range and reducing refueling stops for adventure travelers and commercial operators. Constructed from ¼-inch thick crosslink polyethylene, this tank provides superior durability, corrosion resistance, and long-term reliability.

Designed for plug-and-play installation, the tank mounts securely in the stock location with included straps. It extends 13.1 inches forward and 3.3 inches rearward of the original tank without affecting drivability. The factory fuel gauge remains functional, though it will stay on full for the first 5-7 gallons before moving normally.

Key Features:

• ¼-inch thick crosslink polyethylene construction for enhanced durability.
• Direct replacement using OEM mounting locations.
• Fully compatible with the factory fuel gauge (minor reading adjustments).
• Maintains excellent ground clearance (1.5” lower than stock).
• Backed by a lifetime warranty for long-term reliability.

Fuel Gauge Accuracy & Distance to Empty (DTE):
The fuel gauge remains accurate, but with the larger tank, it will stay on full for the first 5-7 gallons before dropping normally. However, the DTE calculation remains based on the stock 24-gallon tank. For example, at 20 MPG, the true range with a full 40-gallon tank is 800 miles, but the vehicle’s DTE will still display approximately 480 miles.

Durability & Performance:
This tank is built to withstand extreme conditions. Unlike metal fuel tanks, crosslink polyethylene does not rust, dent, or corrode, preventing condensation buildup and fuel contamination. S&B backs this product with a lifetime warranty, ensuring reliability for off-grid travelers, van lifers, and fleet operators.

Installation & Fitment:
The S&B 40-gallon tank installs in the factory location, utilizing included straps for a secure fit. It is designed to work with the factory fuel pump and sending unit. However, high-flow diesel pumps at truck stops may not shut off automatically when refueling.

For van lifers, overlanders, and adventure seekers looking for extended range and fewer fuel stops, the S&B 40-Gallon Replacement Fuel Tank offers OEM fitment, increased capacity, and unmatched durability.
