That price isn't that bad, certainly cheaper than I'd usually find here.
It's the toss up between finding one in this country, paying more and thinking it'll be okay. Vs getting one overhauled in the UK, paying a bit more but knowing it's good. Getting one overhauled here is vomit inducing expensive.
My work car pump died a few months back, I'm up and running with a D22 pump I picked up dirt cheap (like 60 quid cheap), but it's not delivering around 30% less fuel than it should.
