hydroboost converstion on 5.3L swapped K5?

[75K5]

Has anyone swapped to Hydroboost after a Vortec 5.3L conversion? The vacuum booster in my K5 is bad and I am considering a swap to hydroboost. But I am running the 5.3L power steering pump and stock bracket.

Has anyone done this? Does the 5.3L steering pump produce enough pressure? How did you plumb it together?

Thanks!

all I did was swap on a 6.0 pump from a hydro boost truck .

did it have a different part number? How did you plumb in the hydro boost unit? With T fittings?

the 6.0 pump was from a truck with hydroboost brakes. so it was bolt on / hook up like stock and run it .

get a 2003-2004-2005 2500hd with 6.0 and hydroboost brakes . then get the pump for that and swap it in direct and go for it.

see my pic . its .3 with 6.0 pump and the extra nipple return port on the tank . fits in just fine . motor / truck didn't even notice the difference.

hydroboost for stock 5.7 1990 k5

Hello all, switching brakes to hydroboost system on my 1990 k5 with the stock 5.7 . my question is what vehicle should i get the power steering pump from? Some people are suggesting a v3500 truck should bolt right up?

Thanks

I'll try to dig up some diagrams of the 03-05 2500's. Sounds like there's three ports on the power steering pump, and one goes to the hydro unit?

From my research, it looks like I need the hydro-assist assembly and master cylinder from a 73-79 model.
