[RE-wrenches] Generac EcoGen problem

[Rich Nicol]

I've seen a number of Eco Gen's go with no issues for a long time and 2
others blow all the oil out just as Drake noted. Rather worrisome!

The one and only EcoGen I installed blew out its oil in within the first
couple hours of running. 
It severely damaged the engine. Generac did the service and ultimately
replaced the unit. It had something to do with the two reservoirs and the
hoses.
