I've been playing ACD pump roulette on ebay and came across this cheap. However the ad did not state that it is broken.
one of the metal nipples on to which the hose attaches is missing. Can this be repaired? I have parts from my old pump if so:

 

It looks like it but I wouldn't chance I because It could have other problems I would just buy a new one

 

Clean it up. Epxoy another nipple back on. And then run it. Only way to find out. :}

 

**** that, file a dispute with payal/Ebay, get your money back..

 

I would definitely not use that. Who knows what materials have made their way into the pump. Get your money back

 

Pump returned, thanks for the feedback.
Thats the second one i've had to return. Why can't people sell used pumps that actually work?
