vacuum the easy and cheap way

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'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.

The vacuum pump that came with my engine is a stand-alone unit that bolts to the intake above the injection pump and runs off of a single v belt. It is for sale, as I am using the vac/PS pump combo from a 93 dodge

Their are a couple of vacumn pump options,
1. the v belt pump above the injection, the v belt runs off the water pump.
2. A gear drive pump (only) just below the injection pump (this is what I have)
3. Power steering/vacumn pump combo like the 6bt of the 3/4, 1 ton trucks
4. Electric vacumn pumps as mentioned earlier


I have seen all of these in bread trucks when I went to purchase mine dovebid setup.
Good luck

They get kind of expensive....
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.

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.

Not sure whether you guys have them over in the us, But here there are a few other options- any of the small isuzu diesels, toyota landcruiser etc. have a vacuum pump on the back of the alternator, all they have is an oil feed line, a drain line back to the sump and a vacuum line. some even have an extra 1/8" (I think) take off for accesories, heater controls etc. Just a different point of view....

late '90's, early '00 Audi's have an electric brake vacuum pump as well. There about $100 on Ebay.

If you're NOT running a turbo (who isn't?) you can pull vacuum from the engine for your accessories.
Most of us like our turbos, though.

I have a vacuum pump pulled from a running Deutz/Iveco setup in California sold because of Arnold's cigar emissions. Not tested, belt driven. PM if you want it.
