When my pump failed a couple of years ago I replaced it with a genuine one and it has always been quite noisy on ignition compared to before and compared to other people’s td5’s. Don’t hear it with the engine running and it appears to work fine
Bought this off the bay recently
Full set of Britool a/f and whitworth with all the accessories for £60 +£20 postage. There’s a few strap-on bits in there too. I’m hunting a set of metric sockets to replace the whitworth though
