Thread size on sending unit banjo?

[nueve11]

Hi Guys,

Does anyone knows the size of the threads on the oil pressure sending banjo bolt. I know the bolt is an M12 but not sure if a 1.0 or 1.25, I want to clean the threads with a tap as is hard to get the bolt started. The car is a 1988 Carrera 3.2

Thanks,
Rey

Rey,

We're you referring to the hollow union bolt (911-107-709-01) that secures the oil pressure sending unit block to the crankcase? That's a 12-mm x 1.0 pitch. HTH.

Tony,

Thank you, that is the one! I took the sender block out and replace the sender, but now the bolt do not want to start threading back. It looks like the first thread can use a bit of cleaning up. Thanks Again!
