5/16" is the tap drill size ish for the 1/8" pipe, should be about 27 threads per inch. NO you can't just use a bolt to plug it.

most common look like these, but you may find them with a hex head instead of the allen head. Any lowes, home depot, autozone, murrays, oreilly's, advance auto parts will have them.

i guess I could just use the one that I pulled out of the cfm+ were i put the boost bolt
, should be the same size right?? and a little lock tight, just a little fearfull of not having a head and it would fall in over time, sorry about all the stupid questions!!

I thought it looked a little wierd, I was going to check my truck when I left work. That makes sense why that little post is hanging out right next to it.
