For the small filter I bought it off eBay. It is one of those orange WVO heaters. On the other filter I was given a filter heater for a semi. That one is more of a fabric material vs those orange rubber pads. I have each one wired to its own fused switch in the cab.

Just an update here, now that the temps are way low like -10 with wind chills to -40, my filter heaters are keeping me running. The fuel psi still drops but never below 10psi. When I idle for about 20 mins the psi starts to climb back up but once I give it some throttle, it drops back down again. I am heating both filters.

I put a fuel filter heater on both filters. With both filter heaters turned on, there is no change in fuel pressure. Doesn't matter how long I let them run. And has anyone ever watched what their fuel temps are when its cold out? And can someone tell me where my quadzilla gets its reading for fuel temp?

Air dog told me they run into this problem a lot. They gave a number to a shop in North Dakota. This shop makes parts to plumb engine coolant to the air dog pump. It's pretty expensive. They told me filter heater wraps should do the trick.

My napa still said they don't carry them so I had a buddy get one from napa down the road in the next town. How stupid is that?

Put new blower in and wow. Didnt know how bad my other motor really was.

My pressure is good in the morning when I leave for work. That's because I park in my heated garage. Soon as the cold hits the pump the psi drops right to 11. It doesn't slowly go down it jumps right to 11. Going to call airdog today.

Well did cleaned out my system and put new filters on. Topped off with number 1 and cant get above 12 psi. It sits right at 11psi. So thought maybe my guage was the issue. Took the truck over to the local diesel shop and had them test it. At idle they got 11.75psi and at 2000 rpm they got 10.5 psi.

Well sucked the tank dry, drained all lines, replaced both filters, and put 30 gallons of #1 in. Will see how it goes in the morning.

I have drained the separator every time it gels to look for water. I never see any water. This morning I drained some diesel out of it and sat it outside in the cold. It got cloudy real fast. It never did gel or get thick but did cloud over. I'm just going pump the tank out, new filters, and top off with 100% #1 and be done with it. If that doesn't work trade it off. lol

Well the damn thing gelled up again this morning. It's anout 0*F right now. When I last fueled up it was me and 2 other work trucks. Not one of those trucks have an issue, just me. Can I guy triple dose the fuel with treatment?

When it comes to parts I like buying local because it's easier to return stuff. Sometimes I have no choice but to buy online. I am going to napa Monday and make them feel bad. Lol

I have mine in the same spot. Do you run #1 with no issues? I normally run #1 with 2 cycle oil and never had an issue. But like I said this is my first year with airdog.

Well I pulled it in the heated garage all day. I added another dose of Power Service and have been letting it idle outside for about an hour now. The fuel psi is holding. Actually it's running a little higher. Right around 19 psi. I also insulated the pump, filters, and any fuel line that isn't tucked inside the frame rail. Hope that does the trick until I can get more #1 in there.

I assume it is working because when the guage reads zero the engine starts to stall. Soon as it gets below 10 psi I shut the engine off.
