Serial Number Lookups

Hi -

Recently purchased an aircraft with sn 5,615.352.  Can someone lookup this sn for me and tell me manufacture date and configuration? 

Also, I tried to register on rotax and it says serial number not found.  I've entered it with and without the "," and "." and still says not found.

And lastly, I have a BCD fuel pump model 893110 sn 13.4916.  Trying to figure out the age of the pump and if it needs to be replaced since Rotax recommends replacing fuel pump at 5 years.

Thanks
