Thank you for the advice dbrannon79
My factory filter housing is leaking fuel where the 2wires go in at bottom side so I am not worried about heat truck is not driven in winter I am in Nebraska and I also run a 82 Isuzu 4 cyl diesel which has no heater.
I will put in # 1 if I have to use them when it’s that cold!
I am installing a 4770 housing with a wix 33005 3 micron which has a water drain thinking about a mount bracket to go on left fender apron in front of master cyl.
