Black tubing on inlets and outlet

[KatowenMN]

I bought a new liner this year and it has these black things over the inlets and outlet. It won't fit my current connectors. It's a 16x48 pool
How can I adapt this to my current connectors?
Also what's parts to I need for dual inlets? My old liner just had one of each

You need to check the intex website for parts that correspond with that liner -
