I bought the FlowRite Remote Drain Plug kit 6 months ago or so and was still back and forth on installing it after the mixed reviews.
Well I finally committed to installing it and it didn't fit my drain hole as I expected and some folks had posted online. My drain plug hole was way too big for it.
I found and installed this adapter: https://catchalimit.com/products/drain-it-adapter
This work perfectly, plus if the remote drain plug fails or has an issue, I can use my original screw in plug!
I installed my remote mechanism in the right rear compartment instead of in my splashwell. I didnt want to cut a hole in the pretty fiberglass, I was straight up scared.
I figured I open this compartment everytime I launch & load anyway, that is where I turn on my circuit breakers for primary power and power poles power.
I love it. Ill keep it lubricated and report back how it goes over time!
I too bought one a couple of years back for my 2015 Cougar FTD. However, I returned it when I found out the hole was mis-sized. They did not have an adapter at that time. I may try one more time. I getting too old to crawl under and open the drain.
