Fuel Line Length for Espar D2
Installing an Espar D2 in my gas E-250 this weekend and had a question around the fuel line length. As I'll be running an external tank on the rear passenger door of the van, is there a maximum fuel line length I should keep in mind to ensure the fuel pump is able to provide fuel to the heater? Wasn't able to find a specific number mentioned in the install instructions.
I'm assuming it's safe to use the full length of the fuel line provided, but want to make sure, as that will factor into the placement of the heater.
