I am curious because I did.  I realized it almost immediately and corrected it.  The pump seems to run fine, but the instructions say that it WILL BE DAMAGED if connected backwards.  If it is dmaaged can it be fixed?

 

Thanks.

Hey just call up MOss or VB and they will send you a new one. I thought I had a leaky Slave cylinder I bought from VB on my midget and they sent me out a new one. I know that with your problem it wouldn't be right to lie. Sometimes these things happen to us all. I have a solid state on my midget has worked fine for years.But telling you to tell a little white lie on the phone to Moss my fuel pump might just give out tonight LMAO! Good luck

cholwerk,

Solid state components don't really respond to "fixing". Chances are that if it runs now it will run for quite a while and isn't really damaged. If it quits, chalk it up to a lesson learned and purchase a new unit. You'll sleep better. Just my tuppence.

I'm surprised that you didn't do any damage, I didn't think there was anything faster than the speed of smoke. Probably the component most easily damaged would be a transistor or diode which could over current and burn out if left in a reverse bias state too long. If the unit is working fine, then I doubt if there was any damage done at all. Your pump should, in the words of Spock, live long and prosper.

Thanks for the replies.  I figgured the diode was the thing that would go.  Just did not know if the diode was part of the pressure circuit or the pump circuit.  If it is just a diode it should be easy to replace.  Does anyone know if moss sells these diodes, or the whole PC Board?  I could not find it on thier site.

You will find no electronic components separately available for this pump from anyone who sells it.

The only place to get the circuit board is from Burlen Fuel Systems in England http://www.burlen.co.uk/ at a price of £39 plus shipping, which puts it close to the price of a new pump.  You probably didn't do any damage to the pump or the circuit board, they are really pretty bullet proof.  You might want to consider installing a permanently installed back up pump in your car as a precaution, then just leave the SU pump in place.  If/when it fails, you can just switch to the back up to get you home.  See my article at: http://www.mgexperience.net/article/backup-fuel-pump.html
