Was stripping down my MX5 engine and found a lump of rust on a water pipe, i picked at it and it fell off leaving a hole.

It is on an 8mm elbow so I cut the old one off and ordered a 3/8" barbed elbow but it needs a 3/8" tapered BSP tap

If anyone has one I could borrow to do the repair I can furnish you with some goodies when I return it.

Thanks
