Don't do this, wouldn't last two minutes - there's too much scope for deformation under boost - the silicone will just expand and spit the tyre valve out.
Also, if you're going to T into the wastegate actuator feed, have a spare pipe handy for when the original one on the turbo cracks.
I'm just going to reiterate that doing it T'd into the actuator feed is a bad idea imo, completely inaccessible on the HDi.
