Default RE: Vaccum Leaks

After removing my upper intake i was surprised at how many hoses were on it. Every one them was cracked and probably leaking a little. There was 2 hoses for PVC, 1 to MAP(if speed Density) 1 to charcoal canister, and 1 that goes to firewall..can't remember. There was also one thin vac line that went to the back of theintake.
