S&B 47-Gallon Replacement Fuel Tank for 2007-2018 Mercedes Sprinter 144" & 170" Wheelbase

S&B’s 47-gallon replacement fuel tank is designed to significantly increase fuel capacity for 2007-2018 Mercedes Sprinter vans with 144” and 170” wheelbases. This tank replaces the factory 24-gallon fuel tank, nearly doubling the range without requiring modifications. Built from ¼-inch thick crosslink polyethylene, it offers durability and corrosion resistance, making it an ideal upgrade for long-haul travel, camper van conversions, and commercial fleets.

The plug-and-play installation ensures a seamless replacement, utilizing the stock mounting location with an additional rear strap for added security. While the factory fuel gauge remains fully functional, the first 5-7 gallons will register as full before normal gauge movement begins.

Key Features:

• 47-gallon fuel capacity (compared to the factory 24-gallon tank).
• ¼-inch thick crosslink polyethylene for superior durability.
• Direct fit replacement using OEM mounting locations.
• Compatible with the factory fuel gauge (minor reading adjustment).
• Maintains excellent ground clearance (1.5” lower than stock).
• Backed by a lifetime warranty for long-term reliability.

Specifications:

• Tank Dimensions: 98.28” x 15.41” x 14.28”.
• Weight (Dry): 45 lbs.
• Ground Clearance: 1.5” lower than the OEM tank.
• Sending Unit: Reuses OEM unit.
• Price: $1,549.00.

Fuel Gauge Accuracy & Distance to Empty (DTE):
The fuel gauge remains functional but will stay on full for the first 5-7 gallons before registering fuel usage. However, the DTE will still be calculated based on the stock 24-gallon capacity. For example, at 20 MPG, the true range with a full 47-gallon tank is 940 miles, but the vehicle’s DTE will show approximately 480 miles.

Built to Last – Lifetime Warranty:
Made from high-strength polyethylene, the tank is resistant to rust, dents, and leaks. Unlike metal fuel tanks, it prevents condensation buildup and corrosion, reducing fuel contamination risks. S&B backs this tank with a lifetime warranty, ensuring long-term reliability for Sprinter van owners.

Installation & Compatibility:
The S&B 47-gallon tank installs in the factory location and is secured with an additional rear strap. It is designed to work with the OE skid plate, factory fuel pump, and sending unit, eliminating the need for modifications.

For van lifers, commercial drivers, and fleet operators seeking extended range and fewer fuel stops, the S&B 47-Gallon Replacement Fuel Tank is a proven solution offering increased capacity, OEM fitment, and long-term reliability.
