Speak to Gazlowe in Ratchet.
Our racing team is the pride of goblins everywhere. You'd be surprised at some of the people who contribute in one way or another to our team.
You know Gazlowe? He tracks down parts from around the world for us. He even came down to work on one of our rigs once!
A few weeks ago, he said he'd send us a new prototype fuel regulator but it hasn't come yet. He's usually very prompt... Maybe you wouldn't mind going to Ratchet to ask him about it? I wouldn't be so pushy, but the gnomes are gaining on us!
