I know this is an old subject but I do like success. I finally got around to moving the ShurFlo water pump from its factory location (on the floor and hard plumbed to the PEX pipes which is NOT how ShurFlo's instructions point out for installation).
I used two 90 degree bathroom type valves 1/2" x 1/2" pipe fittings to connect to the PEX where the pump was originally located. Next, I used two 1/2" 30" long faucet lines to connect to the pump fittings.
Mounted the pump on a piece of 2"x6" wood that I screwed vertically to the forward section of passenger side bunk water tank area. Made a huge difference in quieting down the pulsating pump. I'll try to attach some picture later.
