Don, those are gray 2" sewer pvc. They all come with rubber seals. I use same type all the way up to the motor. No nuts, screws, glue or anything. We have the white pvc too, for fancy visible bathroom/kitchen use, but I like the gray ones better. They are sturdier (and cheaper).
Tom, with a RWD I would most likely still be sitting nose down.
No white house statements here. Wrong side of the pond.
Tom, I DOW at least 20 mile roundtrip to work every day. Even if your gasifer sits in the shop we may waste equal amonts of gasoline anyway since you claim you never leave the farm.
