SHURflos are well built, and have a good reputation. Also rebuild kits are available.
I notice it doesn't have a pressure switch. When you switch it on, it will run until you switch it off. This could be controlled with a faucet that has a built in switch or a switch next to the faucet. You can get ones that have a built in pressure switch. They will turn on when the faucet is open, and turn off when you close it. External pressure switches are also available, but will take a bit of plumbing to tie them in. I also notice it is 3 gallons per minute. That is way more than you need for a small sink faucet. 1 to 2 GPM would be much better. If the pump is oversized for the faucet flow rate, then the pump may cycle. If that happens, an accumulator tank will help.
This is a 1.1 GPM Flowjet with an on demand pressure switch.

The pipe needs to be at least a couple inches in diameter and about a couple feet long. Cap one end. Use reducer fittings to mate the other end up to the T. Mount it with the capped end up. The tee then goes inline with the hose from the pump to the faucet. The trapped air will compress when the pump pressurizes the water. This style will eventually get water logged if left in use for years, but you will be draining the water system at least yearly so it should get it's air supply refreshed. A tire valve could be put into the cap end to allow refilling the air, but it isn't needed for RV use.
