    Okay the two lines that connect to the throttle body itself? There are two ports. There are two lines. One is bent in a 90 degree and the other is straight. Does the 90 go on the port closest to the drivers side or passenger side? Thanks for all the help fellas

    I jsut replaced the throttle body on mine and If i remember right it is the one closest to passenger but im not toally sure. The real way to tell is to go down by your transmission bellhousing where the lines are clamped together where they are flexible and follow them up and strighten them out so they are perfectly side by side up there. From there it should be obvious up top. If i remmebr right, at the engine the lines were blanatnly bent towards their prospective ports. it shouldnt be that hard to figure it out. /forums/images/graemlins/k5.gif

    Well the lines are out of a donor truck and the tbi system is now on my blazer. I guess what I need to ask is which one is the return port and which which one is the feed

    Juan, you should have just called me. But when you lay them down so that the lines go down by the bell housing, there will be NO question. It'll only work one way... They snake through the garbage on the back, and the shapest bend *close to the TB* goes on the driver's side IIRC...
