used a 4 inch center set faucet. Actually bought one for laundry tubs with sprayer and pull out nozzle. Like the idea for pulling out to was big pots. Nope don't need anything special, just a bit of work getting in there with your arm to tighten the hot side nut. Cold was easier. Scamp
sells the shurflo revolution pump but you could get it elsewhere too. Have to get you the model number. They do use a little flip on/off switch that controls the pump, mounted to the galley fiberglass near driver side bench seat. 12volt wired to your 12 volt panel at your distribution box. You should be able to feed wires behind the bench seats without removing; my bench seat has a little area behind where pex tubing and wires are. Conversely you may wish to remove bench seats if you wanted to anchor wires to trailer floor with wire clips.
Anywho I'll get faucet pic up for you shortly. Got at homey d. Around $65 bucks and change I think. But you may wish other as this might not be high enough arc for you.
