2000 it should be early 10p type unless someone had transplanted a newer engine in...
You can tell by looking at the fuel pressure regulator, on early type it only has 2 hoses connected to it, newer ones has an addional hose which runs to the front of the block (later 15p has an external fuel return gallery).
So early and late type both have the 2 heater matrix hoses going into the bulkhead above the starter/side of cylinder head), early also has a hose coming from the rad to a metal pipe that runs around the back of the head. They did away with this on later types, no idea why - some earlier ones depending on which market they were sold into may also not have that hose/pipe assembly. Just worth checking these for leaks first, I'd expect these to go before a core plug.
