Katz silicone heater pad on fuel tank???
 

They make a 60w, 120w, 150w, silicone heater pad for oil pans and batteries (60w) So living in AK and having some free #2 I am going to put a 60w onto the bottom of tank to plug in while at home. What do you guys think of this?

It won't help heat what's between the tank and injectors. What will happen first thing in the morning? I know from first-hand experience that my bio gels enough at 12* that my truck won't run. I had to use a propane torch to heat the injectors, injector lines and pump enough to warm up the engine sufficiently to keep everything above the flow temp.

There's a few guys on ebay that sell injector line heaters- a set of those triggered by the grid heater relay might help.

Does bio "cloud" like #2? I had my vw TDI gel I mean "cloud" twice on me, interesting enough it started fine warmed up 10min or so take off and on both occasions within a few miles of the house died. So these occurances with diesel (whatever temp. they were treated to) clouded and gelled the intake. I learned this the other day when it happened. I pulled the quick-releasse cap off ff and filled up with 911 start and die again and repeat until i finally left return line quick-release out of ff and continually filled as engine was running on what i was adding and after a few minutes the return started to pull fuel then i knew it was pulling it's own. It these cases it was cold fuel in tank, I have never had it not start but bio would just wax I think????

I really wouldn't do it. When I lived in Fairbanks I never had a problem with fuel gelled in the tank, it was always the filter, and usually right before I was going to change it. Use a good dose of Power Services and it'll be fine. I had thought of this with outside diesel-powered heaters and was advised against it by folks who know more about what hot fuel does than I.

Just re-read your second post...where in AK are you getting BIO?

my bio is gelling up since we had a cold snap here. Im trying to cook up some way of heating the fuel system on my truck. I have a heat element in my racor filter but the !@#$ thing isnt doing anything. I think the guy I got it from gave me a 24v unit =(
