[ROVERNET - UK] Looking For SU Pump Parts

I am familiar with the person in WA doing the pump rebuilds and would not 
hesitate to send one to him. I cannot pull his name or e-mail address out of 
my memory at the moment, but may be able to in a day or two. He rebuilds 
them to the latest electronic specifications. He has written an article or 
two on SU pumps on some of the MGB websites, you might try there.

Rebuilding them is not too difficult if you follow the instructions. Adding 
a diode is a good option. You may need a different cap if you have the flat 
ones. Is your pump a double ended one, with one end the reserve? The diode 
can be made to be either negative or positive ground by reversing the lead 
terminal ends. The diode is connected across the coil itself, not across the 
point as a condenser would be. I bought some used diodes from this guy some 
time ago. These were from units that he had converted to electronic. He is a 
former Navy Electronics Technician that later got he EE degree. Pretty sharp 
guy. He checks all facets of the pumps, such as the coil for shorts and 
insulation leakage, etc.
