I've discovered that my ISRI seat needs to have the air lines replumbed.  Someone had kinked off the supply line because they were unable to solve an air leak problem in the seat and although the majority of the controls, up, down, forward, backward, back tilt are electric it would be nice to have the air controlled portion of the seat, lumbar and flank support functional.  I've attempted to contact ISRI to obtain repair parts or diagrams but was told due to the age of the seat they no longer support it.
Does anyone have a diagram of the ISRI seat air supply for seats around the 2007 vintage? 
Thanks
