Espar B4L M2 Installation on Ford Transit

NOTE a clarification of the routing of air tubes, fuel line and pump power can be found here:

Thanks for checking out our video of the installation of the Espar B4L-M2 heater under the passenger seat, on a 2023 Ford Transit. Our Transit is the Long wheelbase (not extended) and we have a 31 gallon fuel tank.

The Espar M2-B4L is a 4 KW (14,000 BTU) heater that runs on gasoline/petrol and auto-compensates fuel/air mix for elevation up to 9,900 feet.

If you have any comments or questions, please post them – unless you find any mistakes that I made :-)
