Where can I get one? other than online.. hardware stores? etc

 

lol, hardware store. No, either find a speed shop or you could make one. get a piece of metal plate (like 1/4"), drill three holes and tap the middle one to 1/8NPT and get a -3 or -4AN to 1/8NPT adapter. The adapter should be available from a speed shop also.

alternatively you could tap the turbo and thread the -3 or -4AN adapter in. Or use brake line and find an adapter to screw into the oil feed on the turbo so that the brake line can be screwed into it. Stay away from brass if you can (can work harden and break off). Brake line is essentially what a lot of car manufacturers use to make oil feed lines for their cars. It's no better or worse than a stainless flex line.

 

So just use a brake line screw?

I have a brass one on there now..

 

what's a brake line screw? Aside from that, I think that Thumper guy has it. That or just weld it on.
