I had a local shop weld an AN fitting to my intake manifold, but the guy messed up/melted the threads a little bit in one area. What kind of die can I use to fix it? Would a standard die work? The fitting is AN-8.

 

Nothing?

 

use a 3/4-16 die

 

So the thread/pitch on AN fittings is standard? That's what I was hoping.

 

sure is, here is a guide if you ever need it

I know this is old, but I saw it was unanswered when I was searching for the same tools. You can find tap and die kits with lapping tools at knechtionrepair.com
