Pool Pump Upgrade

I recently upgraded my above ground pool with a intex pump. Pool is a summer escapes 330 gallon.
Everything is working great but I need to figure out the cleaning hookups. I was told I need a bigger hose 1 1/2 and adapter to increase the size of the skimmmer plate. I am having a hard time finding which adapter to make it a 1 1/2... Here is my current plate that needs some fitting to make it 1 1/2 inch for a new hose? Any help?

here is the one I have
