Depending on how new you're talking about would mean if you have a hydraboost pump or not. If you have one of those...there are some other changes that need to take place to make it work, mainly brake booster.
Otherwise, if its just a new style regular pump, the lines should fit like they do on the new vehicles with a little "massaging". The lines can be bent a little bit and will be fine as long as you don't kink any of it.
Mine came off of a 2004 Avalanche and was hydraboost, so I just went to the salvage yard and got one from a 2001 pickup and bolted it right up, and the lines were very close.
Mine is out of an 06 3/4 ton silverado HD
You probably have a hydraboost pump then. Check and see if your PS pump has three lines coming out of it. If it does, then it is indeed a hydraboost pump and you'll need to have a hydraboost master cylinder to make it all work.
If it has 2 lines coming out of the PS pump, then you're all good to go. Just route the two lines to the steering box on your OBS and it'll fit in like the old one.
Finally went and looked at it today, it does in fact have 3 lines on it.
So you are saying that I will need to swap to a master cylinder from one of the newer trucks?
I am guessing one of the lines is a vacuum line?
Is the master cylinder a direct replacement for the factory 1990 one?
can you just switch PS pump?
anyone?Quote:

Ever try to stop a hydraboost vehicle when the engine dies? You have to have legs like the Hulk. :laugh:
Yes, Greg, now that you mention it....:LOL:....or when the pump shaft shears off as you're making a tight turn into a small opening.
Back to my question though,
1. Will a hydraboost master cylinder be a direct replacement on my truck?
2. Will a older style pump be a direct replacement for the bracket on my motor?
3. Could I just run the breaks that I have and the pump I have and just cap off the vacuum part?
i Have asked the same question and the response on this and other forums was that you could plug one line and use the pressure line for the power steering in and then the return for the out. The top one is the return and the threaded one is pressure out. The other one is what i was curious about and never got a solid answer. I just wanted to plug it or something but i haven't quite gotten that far on my build so i will hopefully find out by then.
