    I thought I would start a new thread dedicated to the DD51T/F6A vacuum system. Seems that a lot of data is spread out among several threads and I thought a new tread would be helpful. I have a 93' carry, 4x4 with a manual transmission. I have a 2+3 carburetor. Please feel free to add your data to this thread as long as it has to do with the vacuum system.

    To help me with routing of the vacuum lines I went with colored lines to match my vacuum chart. I am a visual person and this helped me a lot. I hope it helps others as well.

    Love the colored lines. Thanks for the post and thread. I would agree that it would be handy to have a vacuum thread in here that is comprehensive.

    Ok....looks like this is my next project. What size of tubing is required....nevermind, found it on another thread.

    Can you use glow fuel tubing (as in model airplane tubing)? I can source that locally in the right size, but the local autoparts guys have either 2 mm (too small ID) or 4.25 mm ID (probably too big).

    Well, I decided to bypass the glow fuel tubing and found some appropriate vac tubing at the local motorsports shop. I'm not going for the color coding....but I did decide to go for the clear stuff (it is really easy to tell which lines I have (clear) and have not (black) done yet). About half way done and it was definitely time to do the lines (some are crumbling / snapping as I try to remove them).

    On a side note...if anyone needs the vac diagrams for their truck, the http://suzuki.epcdata.ru/carry/ site (you'll need to use the translate function....it's in Russian) has them for most models of Carry. The vacuum diagram is under the engine group and 181/emission controls drawings.

    Ok...looks like I got most of the lines done for now. Didn't get the one for the canister (but I think I still have enough for it if I can figure out the routing)...mine is a hair different that what was posted. I did manage to chase one all the way up to the front diff and get a couple lines there too. Overall, it seems to be running far better...and that was the point behind the exercise :)

    Could you post a link to the page with the diagrams. I could only find parts lists.

    Some are similar to GDW's...but this one has parts, rough layouts and such...for many configurations... Doesn't show exact layout, but gives a pretty good idea of what to expect overall.

    For the DB51T:

    There are a bunch of different ones on the site (most models / configurations) once you figure out how they organized it.

    Got the one to the canister done yesterday....dang grommet had me spooked as I hadn't finished figuring out the routing. All good now ;)

    I source all my tubing on EBAY. Lots of metric sizes there. Careful of thick wall and thin walled lines when ordering. Thin wall is too flimsy

    Good point gwd4078. In my case I was able to handle the tubing before I bought...sizes were right and the tubing was not about to collapse under a reasonable vacuum (very important for vac lines!) ;)

    Out of topic: would someone please, in layman's explanation why these small trucks have LOTS of vacuum lines compared to normal sedans? Hmmm I partly know it is used to run actuators etc but why so many?

    I believe the biggest reason is emissions control. A lot of the emission control functions now done by computer were initially done by vacuum actuation. Japan introduced new emission standards for on-road vehicles in the late 1980's (about on par with the earlier kei trucks being imported under various countries' import regulations)...these standards were tough and a front-runner of the time. As many of the mini trucks we see are of that vintage or later, it fits. Most of what the vacuum lines control is now computer controlled (along with many other functions these days).

    There may also be reasons associated with the small engine and trying to get the best performance possible out of it.

    This is based on what I know about emission controls and comparing a 1990 Lada Samara which I owned that had a carburetor equipped 1,500cc engine (~80 hp), but almost no vacuum lines...to my current '90 Carry (660 cc engine, ~50 hp) that is littered with them.

    Thanks, @Anne Sweeney ... I'm no expert, but it fits the regs and my own observations (a.k.a the "that's why according to me" theory) :)

    Great thread here with great info. While inspecting my 2+3 carb I noticed that my "C circuit" which is going from the carb to the "Carb Choke" has the black/green vac line check valve in it as shown(I am assuming these are check valves). My check valve lets no air flow either way. I assume this is not correct? Also I have no vaccumfrom the carb. Plugged at the carb?

    Also should all of these check valves flow toward the carb only. Makes sense but you guys know more than me. THanks for all the help.

    I ordered some of the 3mm silicone vacuum tubing from www.boostcontroler.com Came in the mail today and looks great. Comes in 4 different colors, size looks perfect. I recommend. 89 cents per foot.

    how do I tell if I have a 3+2 or 2+3 carb? do I need the check valves on the carb lines? which way do they go and are they restrictors or one way valves or????

    Hi everybody, I am new here and dont even know if anybody can help me. First thank you to whoever posted the vacuum diagram at the beginning as that has been the most help I have found yet. I purchased a basket case project Suzuki V-DD51T with the F6A engine. My issue is somebody thought they were going to play mechanic on this thing and swapped the carb with a motorcycle carb and I want to go back to the original, all the vacuum lines are messed up coolant lines fuel lines are either wrong or missing. I have been following the diagram from the beginning of this thread untill it came to the thermo switch. Mine has 4 ports and the one pictured has 2. I need assistance there and coolant lines. Is there 4 coolant lines and how do they route? Sould the fuel line have a T in it up by the carb? If not how do the fuel line(s) go? Any help is greatly appreciated as I am starting to wonder what I got myself into.
