15 RXT 260 pump overhaul New seals?

[seabud]

Looking for some advice with the new oil seal in the jet pump. Just installed a new seal with the spring on the lip instead of the metal seal and I was wondering can I get away with using just one with the spacer and the outside seal or do i have to tear it apart again and add two seals with the spring in the lip like they call for 2019 and up Doo's? The parts diagram for 2015 just shows the old seal being superceeded by the new one PN 271002071 and only calls for one with the spacer still? Thanks any help would be greatly appreciated.
