Does anyone here use the Davies Craig EWP or EBP? looking to replace the stock water pump but I dont really want to drop the $$$ for the RCC pump. I was looking at either the EBP or the EWP 80 (Davies Craig). The RCC claims 5 GPM. the EBP is rated at 4 GPM and the EWP 80 is rated 21 GPM but can be turned down with a voltage regulator. Any thoughts and comments are much appreciated!
