Quick question. When you remove the delerin insert to replace the tube how do you get it to go all the way back up again? My delerin insert is about 1 mm off.
Edit: I think the problem is to insert the delerin insert, tighten gently and then put the feed tube back on.
I have been putting the feed tube on and then inserting the delerin insert.
Just push the delrin insert with your thumb as far as it can go and lightly screw down. First put in the silicone tube and then fit the delrin.
