i have run out of vacuum sources for my turbo setup and was wondering if i could put a tee fitting between the manifold and the brake booster or si that not safe?

 

you cna, but the brake booster line is too big, why don't you just tee it off another line that is the same size

stan

 

there should be more sources to use than that.

 

well i noticed on the b18c1 intake manifold there is only one nipple on the back of the manifold and it is going directly to the fuel pressure regulator but there is a factory TEE already there for teh secondary butterflies so i have teed off there 2 more times for teh BOV and teh BOOST gauge and now i need to run a vacuum line from the wastegate to a vacuum source off the intake manifold but there are no more sources and i know if i keep adding TEE fittings onto the same vacuum line everything gets less accurate. so i am out of options unless im forgetting something

 

I'm tapping the booster line except I I'm using a 6 source vaccum manifold and have the right size fittings to fit the booster hose(make sure you tap BETWEEN the check valve and manifold)

 

is this a common problme with peopel using the stock b18c1 intake manifold? i dont see any more vacuum nipples on the manifold except for one on the back that goes to the secondariy butterflies and the fuel pressure regulator. any one notice that too?

PLEASE DON'T waste your money on a Golden Eagle vaccum manifold!!! goto Mcmaster.com and make your own vaccum manifold for ~$20....I did and check this thread-->
