EDIT: it's an M12x1.25

 

It is metric.. um I think it is 10mm, ah, I forget. Whatever is close to 5/16"

 

3/8ths is close to 10 5/16ths is close to 8-9mm

 

you sure its a 10? i can get metric size, i just need to know the exact fit.

TIA

 

i guess ima have to go to home depot and find out for myself?

 

i would say its an 8mm maybe a 1.5 pitch?

 

home depot ain't gonna have it. esspecially not in brass fittings and what not. Go to a real hardware store and fine the size... then get it from McMasterCarr

 

well, i just wanted to take it there to find out what the threading was.

Steve at Stealthmode sent me what looks like an M8x1.5, but the threading is off and the diameter is too small. he's going to send me the right one, just have to find out what it is.

that's why im guessing an M10x1.25, but am not 100% positive.

 

are you sure your not trying to put the oil line in the water coolant passage :P

 

no, its common knowledge that stealthmode fittings don't fit perfectly.

this being that they are standard, and you will probably never find the correct fitting.

just use the stock banjo bolt fitting (built in restrictor) and weld the stealthmode fitting to the end of it.
