As I said something changed in 2003 because the VP44 Note 2003 up are running CP3 not the VP44, maybe I should not post on meds! Tore my calf muscle last Friday went to surgeon this morning to get it repaired. Wow did I screw that post up, sorry guys. from that year foreword no longer needed fuel to supply it's lubrication. I know because when my carter lift pump mounted on the side of the filter housing went south and I drove it for about a month before it died I checked in to this.
