I replaced my Aguajet with the Shurflo Revolution 4008. I also added the Shurflo accumulator. The accumulator allows you to run a faucet at a trickle and not get pulsing water. When I installed them together and presurrized the first time the pump wouldn't stop running. I removed the accumulator temporarily and the water pump pressurized the stopped. When I connected the accumulator again the pump stop when reaching pressure. I was able to use the existing inline filter and the PEX screw on connector to the input side of the Shurflo. I purchased a couple of 90 deg connections to route the flexible hoses to/from the accumulator. I like this water pump so much I don't connect to water hookups any more, I just fill the water tank and use the pump.
