Ok, Ive heard that a few members here are using these to keep there fuel filters from freezing up and the going price for them is under $100 wich to me sounds like a good deal considering even at dealer cost the damn filters are $27.00 each and if you consider the pain in the ass of changing them... Its well worth it to me to not have to screw with that all winter.

Anyways, what im seeing on there website is that they are powered by 12v source. Wont hooking somthing like that up and leaving it on over night drain your batterys? I mean they pull a decent amount of amperage...

If any of you who have these things on your trucks read this thread, id like some insight on how you have it hooked up.

Thanks.
