to the junk yard it is, thanks for the info.if you looking for vacuum. I have found with a few of my builds that many gasoline 4 cyclinder gm engines came with factory vacuum pump. i have used one on my hot rod and a friends jeep, super easy to set up and mine hold 20" hg within 3 secs. and never drops below 16"hg i used a summit racing vacuum bottle which worked out great...extra volume. I went to the junk yard to get a core, and tested it and it worked fine so it still sits under my rod and works great $30. I planned on buying a reman unit and using the other as a core. but it end up working great
I left the web page for summitracing vacuum can, vacuum pump source, vacuum pump info.

I've seen one or two of those on ebay just yesterday.I'm running the vacuum pump/PS pump combo on mine from a Ram. I think they used it for more than 89-93, I'm pretty sure Mine is off a '99 or so.
They get kind of expensive....I've seen one or two of those on ebay just yesterday.
mine was like 2-250, i think, but came with a good power steering pump. Since i have vacuum boost brakes, I didn't mind paying for something that I knew would work well. Sure, other options would work, but to me, a nice readily available part is always a nice thing.They get kind of expensive....
I'm curious how it turned out for you. I already have upgraded my brake booster on my Bronco with a dual-diaphragm one off an F350 (I think it was...it was a long time ago), so vacuum-boost has worked fine for me up to now and I am thinking a 12V pump with a canister for more volume would be the simplest way to get my brakes back to full operation. With the added bonus of having full brakes even if the engine isn't running. A good bonus on an off-road play truck, I think.i think i am going with an electric style pump.
