9M x 38mm Autovac hose

Because these hoses come curled up in a box and theymay have been sitting there for 6 months or so, it's a good idea to roll it out and leave it sit in the sun for a day or 2 or block one end with a sock or something and pour hot water down it. This removes the coiled "memory" that the hose may have from sitting in the box.
