An improved ink delivery system for an ink jet printer having a print carriage that traverses across a print medium comprising an ink source, a print head, and a coupler for coupling the ink source to the print head, the coupler including a pair of flexible tubes for carrying the ink and a Y-coupler for coupling to the pair of flexible tubes and the ink source, the Y-coupler causing the pair of flexible tubes to initially diverge. A check valve is provided to prevent back siphoning.
