CVR Electric Vacuum Pumps VP555

[Rocketman]

After installing a right stuff booster and master cylinder and discovering a hard brake pedal I learned that it required 18" of vacuum to operate correctly.

I already have a vacuum cannister but have ordered the above pump in the subject line. Does this replace the cannister or work in conjuction with the cannister? Thanks

i believe the electric ones work with the vacuum booster. the hydro ones work off the power steering and don't need a booster.

thanks, I have the booster and a vacuum cannister. Will the cannister need to be removed?

I don't have power steering so the hydro is out.

All the canister does is store additional vacuum for your booster, keep the canister and run the vacuum pump to the canister, it will store additional vacuum until you apply the brakes and your pump will cycle less.

I run a vacuum pump because of a low engine vacuum with a large cam. My vacuum pump pulls 18hg until I step on the brake, it then immediately turns on, I was thinking of installing a canister (vacuum reservoir) so I could pump my brakes once or twice before the pump kicks on.

You can also easily add a vacuum gauge for $8 bucks to see what is really going on, see pic below.

yeah my cam is really too large for the cruising I do, but I just like the lope that I am willing to do whatever to keep it. I noticed these pumps are pretty pricey. Thanks for the post.
