Am doing a cummin swap on my 95 2500 dodge, going great, trying to get all the lil loose ends put together. One I can't find where it goes is the large vacuum line that comes off the vacuum pump that t off to my a/c and everything then keeps going with large vacuum hose then has a bolt in it.haha got the 97 dodge 2500 off a guy on the fourm but can't remember his name good guy helped alot, he must have put the bolt in it so I could get it on the trailer. But if I could get some pic of some of yalls trucks to show me where it goes thanx for the help

Vacuum brake booster? I'll check mine

I didn't know they ever came with a brake booster, I figured they would all be hydroboost. Although usually that is the only vacuum item with a "large" vacuum line.

 

[Hurley]

iirc they switched over somewhere around 98. from there and older, the PS pump has the vac pump attached to back. The newer only have the hydro-boost equipment.

this is my truck, notice line & fitting to left of master cylinder

 

[shagy9888]

Yeah am swaping from a 97 truck, and the guy took the hydroboost and had it apart. But the 95 trucks don't have hydroboost,

 

[Hurley]

sorry i got the years reversed, thought the donor equipment was 1995 vintage

 

[shagy9888]

Oh thanx for the help

Was it from a 4wd drive truck possibly went to the TCase to actuate the locking hubs or 4wd? just a thought.

 

[shagy9888]

Yeah both trucks are four wheels drive and got all that hooked up

 

[Jp9519]

Just thinking out loud as some things that were vacuum controledon them. Went to hydraboost in 97 before were vacuum, 97 had vacuum A/C controls, 4wd transfercase, cruise. actually send me your email in pm just found a quick diagram for 94-96 trucks.

 

[shagy9888]

JP has got it guys thanx to all

 

[Hurley]

so what was it?

 

[shagy9888]

Well you were right first hurley but JP sent me a vacuum drawering that shows it so now I got to plug it or find the part to fix it the right way

 

[Hurley]

cool

 

[shagy9888]

Well new problem now junk yard that got my hydro boost off of cuts the three metal lines coming off it that hooks to the ps hoses and dealer don't sell them. And all junk yards I talk to cut them too.

 

[GCncsuHD]

Any hydraulic shop should be able to make you some. If it's anything like GM hydroboost/power steering its just regular hydraulic hose, a little hard line, and flare fittings.

 

[shagy9888]

Yeah I got the rubber hoses just need the matel lines

 

[krehel24]

Napa sales that line in diff lengths with the fittings already on it all you have to do is bend it. If it is all to long then cut it the right length and re flare it, auto zone will lend you a double flaring tool. Super simple!!
