Ok, here goes: I scored a 1987 B2200 with a bad motor. Found a 1997 B2000 engine for a good price that a guy had rebuilt then ran for awhile then replaced with a V-6. My kid said no problem, he could switch the engines out "easy" and he owes me $$$ My kid is magic with a Toyota 22-R but this is his first B engine. He tears damn near every emission part he sees off the truck (we aren't required to pass here) but can't figure out how to get the vacuum lines hooked back up because it isn't a 22-R. The truck will start and runs pretty smooth IF primed with fuel and kept revved up a bit but dies immediately after you let off the gas. I took a bunch of pictures and added them to this post and labeled the areas I have questions about, hopefully somebody here can see something so obviously wrong and stupid that I'll be doing 115 into town later this evening after about 5 minutes work (har) .

#1 - appears to be a fuel hookup that didn't get re-connected but hey, there's a fuel hookup to the left of it that comes right off the fuel pump OMFG WTF
#2,3,4,5,6,7 are orphaned vacuum lines in search of loving, can you help them find their soul mates?
#8 - ridiculous ball chain add on on what I assume is the cruise control cable. This does not appear to line up to the linkage where it should go and seems to be at least missing a part and at most an extremely optimistic try at fixing a broken cable with salvaged crap off an old bath tub plug. PLEASE TELL ME THIS ISN'T A STOCK PART so I can go back to admiring how well this engine seems to be put together otherwise.
#9 - A really hard picture to get of 2 small vacuum ports off the intake manifold between the throttle linkages and the fuel pump. Both of these are joined together right now with a short piece of hose and I suspect the kid did it to either try and be funny or he was hoping I'd never find them and spend the rest of my life trying to figure out why the truck didn't run worth a damn.

Also, it appears that he has run a loop from the fuel tank to the fuel pump out to the filter where it takes a hard 180 and heads right back into the fuel tank. This is pretty funny, right? I mean funny interesting not funny ha ha. Again I suspect the kid of mischief intended to provoke an aneurism. Either he just doesn't get the B2000 setup at all or he's doing it all on purpose to try and give me a stroke so he can swoop in and fix it in 10 minutes and cruise off into the sunset wearing my jacket and drinking my tequila. Any help you can give will help keep this from happening, at least because of this truck. Thanks in advance for your time!

Your pictures with the numbers are too small for me to see well, but I can tell you #1 just goes from the carb to the evap canister (which is not in your picture at all). I'm not sure if it's actually necessary or not with a stock carb. With a larger picture I could tell you a couple that I have removed and capped off.

I posted the pictures at a pretty large size but the site reduces them for some reason. I dumped them on Imgur at , see if those are big enough and if not I'll get them up somewhere huge asap.

a trick I know: Ctrl and + pushed at the same time increases the page viewing / picture size a bunch depending on how many times you push them

Entertaining

I had some links but it wouldn't let me post them.

Update: the truck will start right up if you block off the air intake of the carb with your hands (hard choke). I'm sure this detail will crack the case!

P.S. What do I bribe you guys with? I can't send beer over the internet and I gotta draw some traffic to this thread so I'll have to go with a time honored solution:

I Googled the hell of that manual and found a ton of dead URLS and places where it once was and once I found a campfire that was still warm where I'm positive it had been staying until recently. The manual appears to have gone the way of Sasquatch, at least from here.

if your looking to eliminate all the emissions stuff then its not that hard, ditch the ECU and plug all the little vacuum line, except the one to the distributor and the transmission, make a block off plate for the EGR valve, and will have to re-tune the carb

if you want to put everything back in... then here you go... good luck

I want all that emissions crap GONE, the problem is that all the vacuum lines are plugged right now and the thing won't run. The question is which of the vacuum lines need hooked up to what in order to get it running?
midnightmike   +1y
use the link i posted, to follow what goes where on the ones you do need, distributor, brake booster and possible trans if its auto

block ALL lines, disconnect EGR
in the first pic you posted, #1 is supposed to be going to the charcoal canister, but its exposed, so that need to be blocked
other lines need to be blocked properly, with block off caps, not with bits of line with screws in them, unplug the ECU so its not trying to fight the carb, retune will be needed for the carb

Sorry, didn't check to see if chasing it down would work, got rid of %'s and 20's and it's the first thing up now.
