916is pump and engine P/N questions

Hi All
Just had my new 916is delivered with 2 Rotax fuel pumps.
Questions then - My engine P/N is 916iS2A - I didnt order a high altitude version so 1) are all 916is high altitude versions and 2) is an A version more expensive than a non A one ? (I don't need above 10,000' operating alt)
Second question, fuel pumps - I gather the older Rotax electric pumps had a reduced TBO and that the newer ones last much longer. When did this change take place and any idea if a P/N 889.732 (889.731) dated 03/06/2025 is a newer pump or an old one ??
Don't want to unpack it any more in case it'll need to be returned !!
Many thanks
Nigel
