Inlet Mainfold heater feed pipe

Has anyone replaced the heater feed pipe which runs INSIDE the manifold?. Mine was blocked and has disintegrated. I have one on order from Rimmer Bros, 90611532, but need a bit of advice on replacing it. I.e. does it screw in or is it a press fit. Either way to remove the old hose connection part I will need to progressively drill it out.

Cheers,

Craig
 
The bit where the hose goes. you can see a thread so that screws in.

The pipe should come out with it.
 
The new pipe from Rimmer Bros arrived today. It has a thread on it as Athuy mentions above. I gave the old one a couple of cracks with a hammer to hopefully loosen the thread seal. Then regular spraying with PB Blaster penetrating fluid. Into the vice after this and I had a go with a large stilson wrench, not really expecting it to move. But what do you know it moved! I was thinking I bet this just shears off and I'll be doing more repairs before replacement. But it kept turning and I kept using PB Blaster and it finally came out! It has some sort of reddish sealant on the threads, not sure what it is but I'll find something for when I put the new old in.

Here's some photos.
The bubbly rotten pipe inside the manifold. This was in three pieces.
