As my long power loss project continues, and seemingly, the problem has been found, I am always looking for anything that can be useful to the community. As we know, a vacuum pump is more or less required for the brakes to prevent loss of brakes when the vacuum from the engine is lost.
Is this vacuum pump strong enough for our needs??? if so, the cost isn't bad.
12 VDC 11" HG VACUUM PUMP
item number: 4-1831
PRICE: $18.95

Thanks for any info

Make a reservoir - 3 feet or so of 4" PVC capped and strap it to the frame behind the bumper. That's worth two or three stops by itself. Hook the pump to it and then see how long itruns before it shuts off. Report back.

DOS Tip: Use check valve so that a catastrophic failure of pump or reservoir doesnt leave you brakeless.

Then it prolly lacks sufficient capacity to be a good brake booster pump.

Also, 11" of vacuum is very low for the booster. My engine will hit double that coming off throttle when I hit the brakes, so thats only 1/2 the "power" brakes.
