Which valve for my old zodiac 3.1 ?

[BigDan]

Old zodiac 3.1. (9'4") , it seems to loose pressure from the air inlet valves ( big tubes )
I cant have the exact model and year because the code plate is unreadable...

I ordred Z6500 assy....aint the same...the inlet valve seems to be intgrated to outside part. (Unless it's really tight ,dont want to break it ) and top cap is different

Anyone has a link to models identification & parts catalog...

Thanks in advance
Being born french, my english might not be perfect
