For us guy's running just Bio I don't think the heated lines is going to work without a second tank of dino to start and shut down with. That system won't keep the bio thats sitting in the lines from jelling when the trucks shut down over night. Once the trucks up to temp I believe it would work fine. But how do we keep the lines from jelling when, like in my case the truck is shut down for several day's in 0* temps.
