my brake booster has a T connector for vacuum hoses one side going to intake and the other disappearing inside the fender. any ideas about where and what that line is. my new booster won't accommodate it

That's your Parking brake auto release vacuum line.

thanks, never heard of it I thought the parking brake was 100% mechanical. is it necessary, will I have to put a T connector on my new booster?
