Espar AS3 B2L 12V Heater- Full Kit (Gasoline)

The Espar AS3 B2L 12V Heater- Full Kit (Gasoline) is the classic way to heat the interior of your van using fuel from your main diesel tank. This kit includes everything you need to install the Espar in your Sprinter van and will operate effectively up to ~ 13,000 ft. in elevation with the included altitude sensor.

Not all Espar kits are built the same. These units are genuine Eberspacher heaters with high-quality wiring harnesses from Eberspacher.

Mercedes Sprinter vans: This kit comes with a fuel stand pipe(fuel pickup), not the T-Piece kit that is commonly known to be used. The hoses included in this kit are designed to attach to the factory auxiliary port(with clamps) or you can source the Dorman Auxiliary Fuel connector adapter(Part# 800-188) separately if convenient to your install.

Ram ProMaster vans have an Auxiliary Fuel Port under the cab floor entry. The hoses included in this kit are designed to attach to the factory port(with clamps) or you can source the Auxiliary Fuel connector adapter separately if convenient to your install. Please consult with licensed builder/mechanic before installing on diesel models. 

Ford Transit vans will require dropping the fuel tank on the vehicle, adding an additional fuel pickup pipe and components. We do not offer an Espar - Diesel Transit kit option at this time. Please consult with licensed builder/mechanic before installing on diesel models. 

Muffler Installation: The included muffler does not display which direction air flows. Espar confirmed it can be mounted in either direction, just be sure to follow installation guidelines for proper undercarriage mounting. 

Recommended to add insulation wrap to exterior fuel lines/connections to prevent cracking.
