What You'll Learn

Some Sprinters have an auxiliary fuel line
The Mercedes-Benz Metris does not have a factory-installed auxiliary tap, but the Sprinter does. Some Sprinters have an unused fuel tap installed for drawing fuel from the tank or fuel line. This tap can be used to connect to the fuel line of a heater.
There are also auxiliary fuel tanks available for some Sprinter models, which can increase the vehicle's range and fuel efficiency. These tanks are designed to be installed outside the frame rail on the driver's side, ensuring secure integration without taking up cargo space. The installation process does not require complex modifications, and the tanks are built from durable, corrosion-resistant materials.

Diesel heaters can be installed in Sprinters
When picking a diesel heater for a van, it's important to consider factors that can impact performance, fuel use, and overall comfort. Knowing the basics, such as heater size, fuel efficiency, and important features, will help you choose the right heater. Diesel heaters come in a range of power outputs, with 2kW, 4kW, and 8kW being the most common options. These ratings reflect the heater's performance and determine how much heat it can produce. For example, 2kW heaters are ideal for well-insulated Sprinter vans in mild to moderate climates.
There are several options for installing a diesel heater in a Sprinter van. One option is to install a secondary fuel pump in the diesel tank, which will pump the diesel from the tank to the heating unit. The cold air from outside the vehicle is then pushed through the heater and into the vehicle as warm air. The warm air from the heater unit exits the vehicle through an exhaust, similar to a car's muffler. Another option is to tap into the main fuel tank of the van, although this may be more technically challenging.
There are also different brands and models of diesel heaters to choose from. One popular choice is the Espar heater, which comes with a step-by-step installation guide and video. The Espar is a fairly simple design, and many people choose to install it themselves to save on installation costs. Another option is the Webasto diesel heater, which is also tailored for specific van models, including the Sprinter. It's important to follow the installation instructions carefully to avoid issues caused by inadequate installation.
In addition to the heater itself, there are auxiliary fuel tanks available for Sprinter vans that can extend the range of your vehicle. These tanks are designed to be mounted as centrally as possible underneath the van to keep the center of gravity low and ensure predictable handling on unpredictable terrain. They are also internally baffled to prevent sloshing and constructed with stainless steel to prevent corrosion and impact damage.
