Adding new pump to EVO 13.5?

[jfoahs04]

There are a lot of threads on upgrading the stock EVO pump, but I haven’t seen any on how to physically replace the existing pump. I don’t necessarily need to do it, but a bought a $13 Vivosun pump from Amazon as a backup to the stock. But now that I have it, I’m not sure how to get the old one out if I need to. My hand is too big to reach all the way into the chamber and maneuver, and it seems tricky to disconnect the hose from the elbow on the return nozzle. Anyone have any tips that I may be missing, or is it really this big of a pain? Thanks!

There are a bunch of videos out there, but this one shows disconnecting and removing the pump.

Thanks, tried it and it's super easy. A lot of the videos I saw were pump reviews, not necessarily installation guides. This was incredibly helpful. I bought the tank second hand and the pump was installed when I purchased, so I'd never taken it apart before.
