Dodge Raider 89 vacuum lines setup
      #984030 - 03/20/07 10:10 PM

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.

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.

Ok, i have been fixing some problems, repaired the thermo switch and thermo valve with some jb weld, replaced the distributor vacuum advance unit, replaced the distributor oil seal, replaced A/C compresor and seals, here are the photos of the missing hoses

these are the 2 conectors on the carburetor that donīt have a hose


the left conector on the altitude compensator doesnīt have a hose plugged.



this vacuum valve, switch, solenoid whatever has a broken conection, i have the replacement but donīt know where to plug it.

already fixed that, tested the thermo switch with vacuum pump and boiling water, when it gets hot the vacuum access is closed, the AAP had broken diaphram, replaced and tested with vacuum pump, when you press the relieve valve and remove vacuum fast the engine lowers itīs rpmīs and restores idle speed, i have problems starting in cold climates, i will have to wait for the next winter to see if this fix helps.

i would apreciate if you can post the vacuum schematic.

Ok, i will recheck the conections, kinda get a little confused with all the names, sometimes itīs easier with a diagram, but i will give it a try.

Well, i guess with the diagram and marked conections someone can help me the easy way just drawind lines or asigning letters.

i will do what I can here but dont hope for miracles

lets start with the HAC and trace from there. There are two hoses, hi and low...but we will call them "inner and outer"
based on the physical location on the componant.

The outer one (r) goes to the secondary well of the carb.

The inner one (y) goes and splits into differen directions.
A-- it splits again. One goes to the distributor,the other continues on through an orifice, through a one way valve and on to the intake manifold.
B--it goes to one or two vacuum switching valves and then to the primary well.

(I am looking at a drawing. I have no idea how to scan it into the computer)

At low altitude, the hac opens to allow intake vaccum to escape from the hac to the atmosphere. There fore, the vaccuum switchin valve and hac's additional bleed-air passage remain closed and bleed air is not supplied to the carb.
At high altidudes, the hac closes and the intake mainfold vacuum is applied to the vaccuum switching valve,hac's additional blees-air passage and the distbutor. As a result the vaccuum switching valve and hac's additional bleed air passage open to supply bleed air to the carb. at the same time the distributer advances timing.
