Thanks to my Friend Sakis the heater is now Fanctional. I am very Satisfied of this restoration, even it took me 1 and 1/2 years to find the right diaphragm for the fuel pump. As you can see the other parts of the Eberspacher Heater are in good condition. (The Fan , the heater plug, the electomagnetic valve, the swithes of the housing, the compustion and the precondition chumper in the casing, works fine.)
I Know this type of Heater has techology and design from late of 70s, and it has nothing to do with the new models llike Webasto 12 - 24Volt heaters, that we can find in the market.
When i bought the Snow Trac in 2010 -11 The eberspacher Gas heater was there inside the cabin. Today is still there, but it works now.
