[T3] Fuel pump for EberspŠcher gas heater

I have a question about an electrical fuel pump for an Eberspächer gas 
heater. I'm not at all experienced with electrical fuel pumps, so I have 
to ask you.

I had a spare pump here that I had a look at, to see if I could get it 
running again. I cleaned up the membrane area (lots of white "chalk" 
there), took the membrane and rod out. Is there anything I should 
lubricate this rod with upon assembly? There is what loks to be a hole 
in the side of the pump body for oil.

After that I removed the rear cover (red plastic) to inspect the 
electrical contacts. When I hooked up power, it didnt move, until I 
helped it a bit. What worries me a bit is that there is a nice, blue 
spark on the electrical contact as the pump runs. Since this pump is for 
transporting gasoline, this spark worries me a bit. Should I be worried, 
or is this perfectly normal?

And last but not least, should I expect this pump to suck the fuel up 
from the tank when I install it, or should the dry lines be primed with 
fuel first?

TIA,
