Thanks guys , thats what i was asking about knock offs . Often with an auction image you have no way of know knock off from the real deal . As @KiWinUS said he got his from a trustworthy ebay vendors while ago ,who now would be???? But I have a few tips to go on now.
Sorry if I seem sceptical of so many “melling” named pumps . But why fit a lemon without proper knowledge.
