Espar AS3 B2L 12V Heater- Full Kit (Gasoline)
The Espar AS3 B2L heater Full Kit (Gasoline) is the classic way to heat the interior of your van using fuel from your main tank. AVC RIG carries this kit. It includes everything you need to install the Espar in your Sprinter van, and it operates up to ~13,120 ft. with the included altitude sensor.
Not all Espar kits are built the same. These are genuine Eberspacher heaters with Eberspacher wiring harnesses.

Vehicle Fit and Fuel Pickup Notes
How the Espar AS3 B2L heater connects to fuel depends on your van.
Mercedes Sprinter vans: This kit comes with a fuel standpipe (fuel pickup), not the T-Piece kit commonly used. The install kit hoses attach to the factory auxiliary port with clamps, or source the Dorman Auxiliary Fuel connector adapter (Part# 800-188) separately.
Ram ProMaster vans have an Auxiliary Fuel Port under the cab floor entry. The included hoses attach to the factory port with clamps, or source an Auxiliary Fuel connector adapter separately.
Ford Transit vans will require dropping the fuel tank on the vehicle and adding an additional fuel pickup pipe and components. Espar B2L - Ford Transit Kit option now available!
Muffler Installation: The muffler shows no airflow direction. Espar confirmed it mounts either direction; follow the install guidelines for undercarriage mounting.
Recommended: add insulation wrap to exterior fuel lines and connections to prevent cracking.
