Which suction jet pump

I'm hoping someone here can help me, I've a 2001 1.6 Passat, ALZ type engine.
I had a coolant leat last week (which I still haven't located) but while the bonnet was up, I noticed that the suction jet pump has completely come apart. (I've attached a picture)
Now I think that it shoud be an easy thing to replace, but I don't know the part number.
On Vagcat.com (http://www.vagcat.com/epc/cat/vw/PA/2001/226/49/2839092/#28) there are 3 different numbers for the suction jet pump (i.e. 3 different types of pump), and I'm not sure which one I need.
The one on my car has the nubmers 03709794 printed on the side.
Hoping someone can help me.
Trying to locate the oil leaks on the car, and this is the obvious place to start.
Thanks,
Robert
p.s. if anyone has had any luck gluing this part back together, please let me know.
