In that 1st video above I am sat in my garage (with door open) and I had to give it a large quick foot full to bring it onto boost.
The tee piece connects as follows.....
Tee into rubber pipe to the take off on the inlet manifold.
From the left of the picture a pipe connects to the top of the tee from a MAP sensor. From the right of the picture the pipe goes off to the boost gauge.
