Abstract: A connection includes a first component, second component and a cord member. The first component has an opening with an inner surface and a first annular groove disposed about the inner surface. The second component has a top end configured to fit in the opening. The top end has an outer surface with a second annular groove disposed about the outer surface. The first annular groove and the second annular groove are configured to form a channel in response to being disposed in cooperative alignment. The cord member is configured to be removably inserted into the channel to secure the first component to the second component. The cord member includes a tapered portion disposed at a distal end of the cord member and is configured to provide a mechanical advantage to urge the first annular groove and the second annular groove into cooperative alignment in response to being inserted therein.

Abstract: A valve stem is sized to mate with a filter housing bore. The valve stem has a first and second end and a body. The first end includes a threaded stem portion configured to mate with a corresponding threaded filter portion. The second end has a drain outlet and includes a fitting for a tube. The body has an axial passage disposed therethrough. The axial passage has a divider disposed axially along at least a portion thereof. The divider separates the axial passage into an outlet passage and a vent passage. The outlet passage is open at the first end, at the drain outlet and at a first side passage. The vent passage is closed at the first end, open at a second side passage, open at the drain outlet, and open at a vent side passage.
