[DeTomaso] Brake vacuum source

I have used the evsource vacuum tank, nice unit, the website seems a bit
messed up.
It is basically the vacuum tank available from many sources, i.e...
http://www.summitracing.com/parts/sum-g1464
They fitted a pressure gauge, fittings, one way valve and an adjustable
switch to power a vacuum pump.
I used one on my son's SAAB where the pump alone could not keep up.
Many cars have vacuum pumps for brakes, fyi.. Audi, VW or SAAB turbo's,
fyi..

Some run tanks,mostly plastic, round or weird shapes.
The noisy pumps are these, similar ones made by SSBC etc...
http://www.autoanything.com/brakes/69A3151A0A0.aspx
The separate tank and pump might be easier to fit.
I would seriously ask your builder to tap into your intake manifold for at
least one fitting.
A second one could be for a pcv valve, then see how bad your brakes really
are.
My engine has about 9" at idle, 15" at 2,500 rpm and I just use engine
vacuum and the brakes are good.
I did have my servo rebuilt and the correct vacuum hose, not heater hose,
so now I have an evtank and new pump sitting unused.
If your are not using engine vacuum I would think you would need a tank.
YMMV
