+1 for spare rigs. Thankfully my previous rig is still operational.

The bend wasn't a really tight one, but a short section between two 45 degree barbs. The fittings were a bit too close together, which pinched the tubing i think. I'll see if i can get a pic or three to demonstrate.

Some good news: I got an email from BP this morning and my replacement barbs are about to be sent. YAY
