[DML] SuperCharger and Engine Vacuum

["Nick" <nicholden@xxxxxxxxx>]

Hi,

I have almost completed a supercharger and EFI installation.

My question is how exactly does the crankcase get it's vacuum?? and 
what purpose does the brass tube under the fuel distributor serve in 
relation to this (if any.
I have removed all the old EGR system so do i still require the hose 
off the brass tube to the small tube on the filler cap?? The large 
tube on the filler cap i have connected to the intake before the 
throttle plate.

I didnt want to blow the oil cap off the first time i start it!

Is the brass tube under the fuel distributor feeding off the 
manifold or does it go right through and feed into or off the valley
(crankcase)

How would this function now the manifold will be under preasure and 
not vacuum??  I also have a blow off valve that will re-circulate 
the boost back into the intake at idle.

All advice is greatly appreciated. (hope i have explained what i was 
trying to ok!)

Cheers, Nick - Sydney
