I have acquired a 1955 grey Ferguson tractor and need to modify part of the diesel fuel line by tapping a hole in the Kigass tank (a whole new story!). The fittings are the compression olive type and I thought the thread was 1/8"BSP , it is certainly the same size but a different tpi

Any ideas?

1/8" NPT ? or the straight version which are 27tpi as opposed to 28tpi of BSP

Of course! – it is certainly coarser than the BSP and I had forgotten about NPT threads.

Thanks

That sounds likely as NPT are used on fuel threads if I remember correctly. Incidentally, if you haven't already found it'd be worth logging onto the Grey Fergie Forum as it's a mine of useful info – helped me no end with my TED20
