I have been using the vacuum hose diagrams made by Don Huysmans to check my setup, this helped a lot to find some problems, but my vehicle is a 1989 Dodge Raider 2.6 manual AC with altitude compensator so it has some extra things.

Here is a list of problems that where detected.

The vacuum delay valve (small white, black and yellow cylinder) was plugged to the auxiliary acelerator pump instead of the manifold conection wich had no hose, when i removed the hoses fuel came out of the vacuum lines and vacuum delay valve, i used a vacuum pump to test the auxiliary aceleration pump vacuum conection and fuel comes out from it when you apply vacuum.

The thermo switch (2 vacuum conections and bolted to the cooling system) has one broken conection (the one that should go to the auxiliary aceleration pump) need to get a new one, but how do i check the parts that where exposed to fuel before replacing it? (AAP, vacuum delay valve, etc.).

The altitude compensator has a broken conection (the one that's single) i already have the replacement but i don't know where to plug the missing hose.

There is a small part on the fender that has 2 vacuum hose conections and a electrical conector with 2 wires, one of the vacuum conections is broken and the electric conector is missing.

The carburetor has 2 capped conections, where do i plug them?

I would apreciate if you can give me the information.

hang on and i will try to help while I have time.
Part numbers? I wish i knew how to get those.

The hose lines I might be able to help... I am lookin in a chiltons mitsu book and it might take a minute...
(if you posted pic's, they are not showing up)

I will try to figure it out anyway

re-phrase the question if you want

what do you mean? the outer one on the HAC(low altitude) goes to carb secondary well, and the other middle one (high altitude) goes and splits a couple times going to distibuter, the carb primary well, through what appears to be a check valve then splits some more and finally connests to the top of the seconarey air contol solinoid valva.

AFTER the "check valve" or whatever it is it splits and goes also to the top (or end) of the throtle opener control solinoid.
I forgot to mention that

The thermo switch (2 vacuum conections and bolted to the cooling system)
the outer one goes to the AAP
the other (inner) one goes to another valve looking thing that is unmarked on this page. It has 5 ports (4 low and 1 high). The thermo switch inner one goes to the high outer one.

but how do i check the parts that where exposed to fuel before replacing it? (AAP, vacuum delay valve, etc.).



well just try to figure what they do,and simulate it somehow

this device appears to be way down below the throttle on the intake. Also the "AFTER the "check valve" or whatever it is it splits and goes also " to this device and splits and then to the secondarey air control solinoid valve.

I forgot some more... it goes thru an device on it way to the carb primary well. The device has 2 hose connections, the other is FROM the carb air horn....also before thid drvice there was another split. it goes to the "vacuum switching valve" which has three connections. 2 on the ends and one on the side. one of the end ones goes to the carb air horn and the other is from the alttidude copensation.(the one we follows here) now the side connection goes to the a carb at a point about where the throttle would close. appears to be intake vaccuum though.

the side connection of the throttle opener control solinoid
goes to the "dashpot and throttle opener" device.

The two connector thermovalve to AAP doesn't *need* to be reconnected. It only operates the AAP until the engine reaches 88 deg (i think) then it shuts off vacuum. So once the truck is about 1/2 warmed up. Mine is disconnected and I don't notice much of a difference when driving cold and there is no noticeable stumble. Just some food for thought. I have 87 factory hose diagrams for fed, calif, and high alt. I'll see if I can picpost them up for ya.
