It's much better and much easier to just keep all the hoses off the part. Infusing from the centre is a good idea for larger parts, but for small parts it is really unnecessary and can cause you issues like you've experienced. 

Just infuse from one side to the other. Run your MTI hose down just the one side. Less issues, and you'll use half the amount of MTI. How big is the mould? If it is under 0.5 metres wide, I wouldn't even bother using spiral hose on the feed side.

For large infusions, I take a strip of flow mesh an stitch it to an omega like shape around the spiral feed tube. With that technique the spiral tube can be set off from the part, and leaves no traces at the part at all. Dd compound sells a product like this if you need further clarification.

Run the feed spiral up one side and the mti up the other.
