The hand pump faucet on my 1998 Jayco Eagle has failed. I think installing a 12v pump should be an easy thing to do, but I'm having trouble figuring out where to install it and how to get the power to it. I am very handy overall, but I am electrically challenged and really need step by step instructions. Here's the cabinet under the sink: It's not very wide - maybe 12" on the floor and 16" higher up. This is where the original onboard tank sits. Can I install the pump here? There's power running through it. Can I splice in here? Here's an area under a bench adjacent to the galley. You can see where the city water comes in, and the black corrugated tube is the water line from the tank. There's power here, too. I appreciate any help you can give - thanks!
