    I am looking for a Hydro-Boost set up for my Blazer. I have 1 place checking to see if they have one, he said the pump is a higher pressure, is this true? I thot the only difference was the return line on the reservouir. I read just last week that the pumps were the same except for the return line so I may not get it, and just T it into the P/S return. Provided he has one. If this is true I will just tell where ever I get it that I am gonna get a new pump.

    The 2nd place said that the yrs matter. I didnt think that the yr would make a difference. They didnt have one anyhow, for the yr I asked for.(86) The 2nd guy was a total jerk anyhow. This used to be my favorite junk yard till they hired this guy. He is a rude obnoxious know it all. I used to deal straight w/ the owner, and could haggle w/ him, and he let me in the yard to look around, w/out having a specific part I was looking for. How many times have you been wandering around a junk yard and stumbled across something?

    Anyway! I did get a lead from the 3rd place, to a yard that has mostly trucks. What should I expect to pay for a Hydro and the lines?

    One last question, does the Hydro hold a reserve like vacuum does after the eng. is off? I would assume it does, but I would like to know for sure.

    Thanx!

    Not 100% sure of this but I don't think it holds a long reserve. My brother in laws Chevy with Hydro assist brakes are funky when the engine isn't running and it seems like no reserve (don't ask me how I know [​IMG]). As far as years being different, it may be the same difference as regular boxes and pumps. There was a switch between flare and o-ring seals for the lines, and someone like Boss should be able to tell you what years had which (probably the same for hydro assist), which is probably the reason he said years matter. Same token though, if you get the donor pump AND box from the same vehicle it shouldn't matter, they will be both one or the other. Hope this helps.

    Thanx Keith. I found that one when I did a search on this earlier today, and saved it for reference. Definatly a good one.

    I just got off the phone and found one locally. [​IMG] The guy is a bit leary of it tho, he said it has been sitting for a long time at his yard. He did not know if it was still a sealed system or not, so I will have to drive up there tomorrow. (maybe Ill drag my butt up there today) LOL!

    Cross your fingers for me! May even get it cheap since I will be taking a chance on it after sitting so long.

    One note, there is a difference between boosters (the amount of assist) from Blazers and K30s. Don't know about the 3/4 tons. Found this out the hard way when someone installed a booster for a M1008 CUCV on a M1009, made the brakes REAL touchy 'til we figured out what the problem was.

    Real trucks don't have spark plugs!
