    Went to a 4x4 club meeting last night and ended up leaving with a Howell TBI fuel injection setup. Got the whole shebang TBI with Quadrajet carb adapter plate, fuel pump, all wiring, instruction manual and the computer with chip. All I need is a new o2 sensor bung to weld into my header and to make a hole for the fuel return line at the fuel tank. I think I already have that part figured out though. Some other minor stuff like fuel pump block off plate and figure out how in hell I am going to get the wiring from the cab to the engine or vice versa. Them computer plugs are pretty big. Even comes with the stock g.m. plug so you can check the computer codes.

    Got it all for $300.00 Called Howell today to make sure about what wire goes to what. He was kinda gruff at first and said that he labeled all the wires and I told him I was a 2nd owner and there were no labels so he setteled down and gave me the information no problem.

    Outstanding!

    A suggestion on the wiring..........we put my computer behind the glove box on the heater box...........ran the cables/plugs right through the firewall through an existing hole that was there.........about 6" off-center of the motor to the passenger side and up by the cowl. Hope that helped..........let me know if you need pics or anything.

    Congrats!!!! I saw somewhere once about adding a fuel return line. There isn'tone on you sending unit already?

    Anyhow, dont remeber where i saw it, maybe here, but the person used a fuel filter from a 68 or so Camaro. I guess it has one inlet and two outlets. they just used the second outlet and connect their return line to it. Not sure if that woudl work or not, but I thoguth I would pass it on..

    Well, good find at a great price!

    Later,

    Thanks people. Been busy as a one legged man in an ass kickin contest. I have been reading a good bit, but if someone answered what I would have said I did not bother to post.

    Mudzer, I been all over the place, hows it been going, have not seen you on ICQ in a while, drop me a lline and tell me how things have been.

    KYLE, BITE ME, go work your yer rig, you aint got time to talk trash!

    Blazin OR, thats exactly where I want to put my computer, if you have any pics of where you went through the firewall it would be great. I cant remember any holes there. I may have to go through the a/c box, there is nothing in it anyway.

    Thanks folks

    You need the return line going all the way back to the tank, runnining it back to the filter would be the same as plugging the return line at the TBI. As for the wiring, on my '83 I ran the plug through the wirewall where it goes on the originally fuel injected trucks, just used a hole saw. I fabbed a couple mounts above the heater box similar to the OE ones, and welded them in.

    Yep, I have a 77, only thoughts were to go to a junk yard and find a tank out of a F.I. blazer and get it tank, sending unit, in tank pump an all. I also have a junker 2wd that I have been scavaging parts off of. I may just take of its filler neck and weld in a return line nipple in it and replace my stock one with it.

    Got all kinds of options to do. Probably going to be a week or two, but I cant wait to get this thing on and see how it performs. Hopefully I wont be watering my eyes on the trails anymore when I hit those steep hills. Also wont cause it to die on the EXTREME uphills either.

    Thanks all

    I bought a tank out of an '87, the FI tank is the best way to go since it has the proper baffles for the pump. I have helped my brother and a couple friends modify non-FI sending units for the return line and pump. Just solder (I prefer using a propane torch to a gun) the return line into the sender. If using a non-baffled tank, you will need to keep a little more fuel in it than normal (don't run it down as much before you fill it up). However, since there is a readily available FI tank that fits, I'd go that route. The ones I modifies were in my brother's '70 K5 and a CJ, both of which came carb'd only. If you get a junkyard tank, put in a new AC Delco pump anyway to avoid any future hassles.

    no more hick-ups and cold start worries. :)

    its on the list, just a little further down than id like.
    i can help you with the filler neck thing though. my old tank is still hanging around and the neck has a spill over tube on the side of it. i have seen where titanic used this on his fi conversion as a return line. let me know if you want it. floridak5@aol.com

    Do yourself a huge favor and get an in-tank pump assembly (or the whole tank with it installed). They are so much less trouble than external pumps, and there were a lot of blazers that had EFI.

    I've had way too much bad experience with external pumps for EFI. Ugh!

    Possibility on the write up, would be a tech article on how to install. Robbie, thanks for the offer of the neck, but I took the one out of the 2wd beater in the back yard and am going to add an extra nipple to it for the return line.
