Which flush kit?

[Toger13]

Hi I have just bought myself a new toy a 21ft bernico with a 300xs, before I pick it up and use it I want to sort out a proper flushing kit out on my old XR2 I cobbled some thin pipe together to do it but it wasn't very reliable and often fell out

I see there are 2 kits that say they fit the sport master bottom end but they look different so which would I need on my engine?

843122T01 Or 848998A 1

Thanks
