Richard,
That is a dual polarity pump. So no worries about wiring it up wrongly. It is 
the AUF301/303/305. I have never been able to identify the differences if any 
between the three. This one is an original SU, not a later Burlen-SU. It dates 
from around the '70's. Early ones had a metal capacitor.
It looks to be in really good nick.
Clean the points before fitting using some flower paper. It is a bit fiddly. 
Also check if the adjustment of the points is OK.
The space between the front of the points blade and the Bakelite pedestal 
should be 0,9mm. the space between the lower protrusion and the top of the coil 
housing should be 2,7mm.
Try the pump before fitting in the car. No problem running it dry for a few 
seconds.
Cheers,
Kees Oudesluijs
