Yeah that's what the guy at NAPA told me as well.

I was able to get the hose fitting out by filing down some channels from the inside to weaken it, heating it, and then chiseling it out. Easy peasy!

Next, I'm trying to borrow a heli-coil kit to avoid having to buy it. But, is there any reason why it is a bad idea to tap to the next size thread, 7/16-14? There looks to be enough material that this would be fine.
