Can this replace an identicle already installed one without anything else needed?

Yes, but you will need to use a good sealant around the outer flange.

Do you add a hose to the vent hole and tank?

The hose from the vent hole (or the fill tank itself) to the tank should already be there. This item does NOT include any hosing - just the port and some screws to mount it.

Good product at a good price

Bought this to replace my old water fill on my 2016 coachmen camper. This was a good fit. This was a good price. Definitely satisfied with this purchase. And recommend to anyone looking to replace their water fill on their camper..

Quality material / Easy install with 3.5" Hole saw

You can tell this is a quality product as soon as you pick it up Install was simple in the side of our camper van - Not many stores carry a 3.5" hole saw so I recommend picking up one on Amazon as you buy this HELPFUL - Had the hardest time finding tubing for the 1 1/4 barn fitting on the back but we found that aquarium stores carry tubing ( we filter our water with a berkey after so not worries about what kind of tubing we use for filling the tank ) Installed with putty/silicone and have an water tight seal No issues with cap staying on I highly recommend this to anyone
