How to determine which Type I have

[Bustech17]

I need a fuel pump for my Laser 560, but there are two types to pick from. How do I determine which one I have? The only depiction I can come up with is in the serial number. The serial is 04255 H0FF560B. Am I to assume I have a type "B" since the end of the serial is 560B?

Thanks,
Des
