As it says in the title, I am looking to replace the petrol tap on my 1936 Blue Star 350. There are so many on line and I'm not sure of the thread diameters. The top one is bigger than the bottom one. It's a Ewart with a patent number 342560 stamped in.
Any suggestions gratefully received, just need a tap to get the beast on the road.
