Just a question for clarification about the evo sensor, can I just unplug it or do I have to use the delete kit?

You can run either pump but if you run the regular pump you'll need to T the return line since the hydroboost system has 2 return lines. People have done it either way. Do whichever you feel most comfortable with.A few years ago I converted my 93 Chevy G20 Van's vacuum brake booster to a hydrobooster. I got it off a 92 G30 Cube van.
On my van every thing lined up correctly.
I have never had the light pedal I expected. It is closer to a manual old drum system currently. All works fine just takes a strong push to make her stop fast.
Reading the thread I saw a post about matching the hydroboost to the correct pump.
Please tell me how to do that. http://www.gmc4x4.com is no more…
I have been told to change the master cylinder to Corvette master cylinder and change real drum brake’s wheel cylinders to larger pistons, which I have done. (This a 93 G20 Van with disk and drums)
I get two versions of this: I need a hydrobooster power steering pump, or I do not need a power steering pump for a hudroboost as they use the standard pump.
Which is it?? From reading this thread I feel it is the pump.
One other version is I just need the higher pressure spring in my standard power steering pump.
Please advice.
Thanks.

If you look on Rock Auto they show the power steering pump without the reservoir with no mention whether the application is vacuum or hydro brake system. Master cylinder should be the same but you have to be careful that the rod that pushes the master cylinder from the brake peddle is the correct length, as long as you swapped the rod in from the donor you should be good.I did but I need something to increase the power, as it is now it is a two foot brake...as in I have driven cars where the power brakes are so powerful I only needed one toe to stop. Most cars I now have only take my toes to stop. This van takes a whole foot for easy stops but a full panic stop needs two feet to really make her stand on her face. It is not right.
A company in CA that does these conversions mage suggestions like to Corvette Master cylinder and wheel cylinders which helped, but not enough.

Well I just picked up a k2500 with hydroboost and I have a nbs master cylinder for it, I'll see if it will bolt up with no issues. Might have to wait till weekend before I can get to it and let you know through. I know the bolt holes line up I think its just the part that fits into the HB is bigger on the nbs MC so thats where the problem is. Unless the HB on my 2000 K2500 is different or was replaced before I got it.
I decided today that I'm switching my 97 obs to hydroboost. I just started LS swapping it. Lq9, big cam, gen 4 rod, holley intake, Terminator Xmax with a built 4l80. Currently painting the firewall on my OBS as I didn't do this originally. I still have my 06 denali that was my donor. Im pulling the hydroboost off of it. I've removed the vacuum booster and pedal from the OBS. But, my pedal off the denali has all sorts of plugs and cables. What will I do with all those, specifically that cylinder with cable coming out of it? I can take pictures if needed.
