thanks ...I got it from a seller -'UPGR8' on amz - 2 years ago
I was going to replace them with the original GM hoses but that turned out to be a no find situation.
The hoses come in different sizes - diameters and thickness of the inside (have to get a tight fit) so it was a little project. Also I was not sure about the material as I heard that some rubbers and plastics are not good for the air flow or fluids.
The material has held up and they have remained tight although I had to tighten up one end after 2 years.
I searched for the hoses and these came up - they had blue, green, black, red, - not sure about orange
The performance definitely improved after these were new again - I think the old hoses were about 15 years old so they were almost rock hard and dust falling off.
