[V8] Fuel Rail

Since there has been some posts on this I thought I would mention something.  A few weeks ago I was working on something and I had a 10mm in my hand and I placed it over one of the cap nuts that hold the fuel rail down. To my surprise it took a full turn! I hit the other 3 and they all were not as tight as they should be. I dont know the spec for these bolts so I did not want to over do it, so I just snugged them down. Just for kicks I checked the header bolts. The bottom one on the drivers side closest to the fire wall is a real PITA to get to but they were all but one in need of a wrench as well. WHAT A DIFFERENCE when I drove the car! Instant throttle response, mid RPM surging gone away, big ass smile on my face pulling to red line! I think if your injector seals are in good shape this could help you out. Also check the 12mm bolts on your headers. As for the rail nuts, does anyone have the specs on how tight they should be? I would like to redo them and know they are not o
ver done. Happy New Year to all!
