    I'm getting my 82 GTSi ready to ship to its new owner. The original fuel distributor was sent to Larry Fletcher to rebuild along with all the steel lines being sent to Portland Oregon for replating.
    While this was being done I purchased another fuel distributor with attached fuel lines to use later on as reference to how all these lines get reassembled. Thought it would be helpful to the new owner to have this second fuel distributor system installed for his reference. Was just matching up what is configured on my 85 QV to this 82 Ferrari. Both fuel distributors are
    Bosch 0 438 100 034 units. I've got all the lines attached to the injectors with exception to #1-2 cylinders on the front bank. It appears these lines are too short to run parallel with the others. What am I missing here? Thanks for the input

    Each one of these lines is feeding a designated cylinder correct? Not just," these 4 go to the front bank and these 4 go to the rear." In any order.. ?

    No, all the CIS injectors spray continuously so any injector line can go to any cylinder. However, don't know if the injector line routing is identical, or not, for an '85 euro and '82 US (there are some other components on the top of a US version that a euro doesn't have).

    Far Out! Thank you sir! I've been at a standstill all day prusing every post/image on the Internet trying to understand what's going on between the two systems. ( with no luck I might add) when I purchased the car they had used some kind of surgical tubing? As fuel injection line. It was always my intention to just match up lines with what was on my QV.. my heart seriously dropped when the last two lines were 2" too short to reach the last injectors. LOL.
    I have pictures of all the US version pieces, just poor quality pictures of the injection lines as they were run. MANY THANKS STEVE!!

    NO. The line routing is NOT identical throughout the 3x8 line.

    I don't remember the exact year or order but pics here should help. Here goes:

    In one set of years, the FD was 'split' East-West, with 9-12-3 o'clock lines going to one bank and 3-6-9 o'clock lines going to the other bank. Other years the FD was 'split' North-South with the same effect: 12-3-6 o'clock and then 6-9-12 o'clock lines.

    On the injector end, the 1-4 lines stayed collected until directly under the throttle body (TB) (80-82 IIRC) then 'split' to each cylinder. Later, the 1-4 lines stayed 'collected' until several inches right of the TB and then split off to each cylinder. The 'early' injector-side of the lines are straighter and the 'later' injector lines more curlly-cued.

    A BIG 'IIRC': The 12-3-6 o'clock and the 9-12-3 o'clock lines coming off the FD went to Bank 5-8. Big 'IF' here. Sorry. Check some pics in this forum. Check several sets of pics as somebody like me with an early FI car swapped lines (See next paras) for safety reasons.

    I believe this was done for safety reasons as a loose fuel pipe COULD jam the TB Open or Closed.

    That happened here quite some time back. The throttle Jammed OPEN, quick thinking he turned the ignition key OFF one click, and saved his son, himself and the car.

    Hope that helps. :eek:

    Mark good morning!
    Yes, This information very much helps me out. My biggest concern was that each line went to a designated cylinder and this was not making any sense with what I was seeing in front of me, or corresponding with a few lines on the 85 QV. Posted pictures are such that it almost impossible to trace each line from the injector to the distributor. Many thanks!

    Great pics Steve. :)

    I believe they pretty clearly show what I was trying to convey.

    FD - 'split' East-West.

    9-12-3 o'clock lines going to bank 5-8.

    3-6-9 o'clock lines going under the Throttle Body and then splitting to each cylinder. You can envision the possibility of a line or more shifting and possibly interfering with the throttle linkage.

    Kim,

    Consider getting hold of Verell (Unobtainium Supply) in this forum. He has all the new correct lines for your car from the OEM manufacturer.

    It is a good deal.

    Awesome pictures Steve, thank you! I'm sure this will help someone else in the future also. Mark, I've already purchased new distributor lines from Verell, just never had the time to complete the project! Will leave that for the new owner to complete. :)

    I have a set off a car so Ill take pics 2morrow and post. With this set you can trace every line.

    It will become MUCH clearer.


    I may have lied earlier about the North-South 'split' at the FD side. :( The East-West split still holds.

    I looked for pics but couldn't find any. All were East-West splits. I am 100% sure I did not 'make that up' but at this point, who knows? :eek: Maybe my brain has been rattled by 'big guns' (firearms, mainguns and cannons) too much over 33 years and it is catching up with me. My wife thinks my brain is rattled so ......

    Until I find some pics, my apologies.

    Haha! Thanks Mark! I am literally one fuel line (running from the fuel pump to fuel distributor ) away from firing this thing! But wouldn't you know what the last line, connections are different sizes. I must have made 30 trips to town (12 Miles each way ) over the last few days just for piddly items such as this.. sold it has a nonrunning vehicle that needed reassembled but really want to help the new owner anyway I can as this will be a very nice 308 with some effort put her way.

    Your US '85 is a K-Jet with Lambda system (no VLV but with throttle microswitch); the other pictures are earlier F models using K-Jet without Lambda (with VLV but no throttle microswitch) - they use different throttle bodies.
