    I haven't done this yet but I looked into it already for my 72. You have to remove the rear most support from the fram and move it back closer to the bumper. Then you are going to need to make new holes for the hangers and it should fit. Someone else who has done this might know if that's all, but from what I understood, that's it.

    Just out of curiosity....how many gallons would an 87-91 K5 hold? I'm getting pretty tired of filling up my stock tank every 150 miles!!!! [​IMG]

    31 Gallons usually. Some Blazers came with a 10 gallon tank, but the one I talked about was 31

    I've got a 40 gallon tank in my Blazer and I'm also going to do an FI conversion (on the back-burner now because of lack of job). I have a couple of external fuel pumps that I'm going to use: One to supply a reservoir tank (a fuel dry sump tank, if you will) and one to supply fuel to the rails from the reservoir.

    I did the 31-gallon 73-91 K5 tank install in my crewcab shorty. Not a factory finish, butfairly straightforward. One crossmember (an a shock!) had to come out. Its a stock TBI setup too.
