I pulled my fuel heater relay years ago and put it in the console as a spare. I have installed a large fuel cooler that I do not cover up in winter with no issues. if I lived in Alaska or Northern Canada, I may install an aftermarket fuel warmer that would only come on in the coldest weather. In the Midwest, I have not ad a problem with fuel ranging from Dino to B-20 in the winter.
For me, only outlived Government Regulations are more useless than the fuel heater.
Racor makes a good fuel head and filter (I use the 2 micron). Had I not made my Mopar to Racor adapter that I am still using, I would have bought the Racor head, made the WIF adapter I posted the drawing of, removed the fuel temp sensor in the old head, mounted it into a plug with a blind hole using epoxy, and got on with life.
Here is a drawing of the WIF adapter I made, not rocket science.
