Webasto, etc.

[MtLaw]

Hello all,

Still trying to figure out systems in my 85 prevost.  I have a Webasto that seems inop, but I believe it worked earlier.  There is a Boiler Fuel Gage on the systems gages, but I only see one fuel port and the fuel tank area is sealed.

I am still trying to figure out what the black tank is for in the other photo.  I think it is part of system which allows heated water/coolant to move around the coach both to heat the engine from the wabasto and heat water as you drive down the road.

Ideas???
