just did an top end rebuild did a bone head and did not mark my lines like I should have. I had a blown head gasket. Long story short I hooked up my lines to where I am pretty sure they are to go. Have some guys that work with me with same engine in a parts truck that has a few lines that are not like mine. I start my truck and starts off running like a champ then gets to where it acts like it is starving for gas. I have raw gas smell pretty bad. Pulling lines I found the vacuum line from the air intake box that hooks to the small line traveling between the upper plenum and lower plenum that goes to the fuel rail has fuel in the line and in the box. Any thoughts? Something seems to be hooked up incorrectly but I cannot make heads or tails on what could be pushing fuel thru the line.
