Sorry, not got round to measuring the thread as yet…….. to much happening at once !!!

Hi, Yes it is on the pipe to the sump extension. There is also 3 on the ball valve, one on the oil pump inlet and one from the breather tank to sump pipe. I agree by colour and Barrys belief in affordable aerobatics that it would be a commercial low cost part. It is close to a power steering fitting...

Good evening,

Does anybody know the make/ name of the oil fittings used by Barry Smith on the oil tank and Ball valve pipe fittings.
We have one that the olive has disintegrated on and before looking to change it all i thought it was worth asking.

Many thanks
Toby
