HMMMM.. These are two conflicting views. I will add this: when I went to replace the filter, I thought I would relieve pressure at the schrader valve at the end of the fuel rail. The car had been sitting for about one hour. There was no pressure or fuel spray. Is there a check valve to keep pressure in the rail? Also when you guys turn your key to "on" can you hear the fuel pump cycle when sitting in the driver's seat?
