I was wondering where on the ecotec do you release the fuel pressure because i need to pull the fuel rail and get it tapped for my fuel pressure sensor. I was told it was the schrader valve. I need like step by step instructions so be a little specific. Thanks
look for the odd thing sticking out of the metal fuel line that is the pressure tap
remove the cap , and then press the stem
and that is were you need to adapt for the pressure gauge
