Turbo feed thread size.

Can someone confirm what thread size this is. I think currently I have a 3/8" fine thread bolt in there sealing untill I get the correct fitting. See pic below.

Thanks

Probably M10 fine.

BTW that port is used for fuel injection pump lubrication, not turbo.

Thanks. Yeah, I think i remember someone saying that. It should still be ok to use for the turbo though shouldnt it? IP comes off the block on my engine (factory fitted).
