A replacement oil feed pipe suitable for the BSA C15 and B40. Just the head end is pictured, but the pipe has an overall length of 20 inches. Also fits the B40WD, and the B44. This is equivalent to BSA original part number 40-0183. The tube has a diameter of 5mm. This is quite easily bent to shape, but if you would like the best result, then I suggest a 6mm automative pipe bender, as used in the making of brake pipes.
