have, is "user friendly" and would be a good companion to the "official" company books.

Nice thing about Montana, low humidity so cars don't seem to rust.

Just as a side thought. The best fuel heater I've found is to run a loop of the water lines into the fuel tank. A person still has to have the unit gel free enough to start, which isn't all that difficult, but as it warms up the fuel then is heated to the approximate temp of the radiator. (minus radiation due to the cold, but still a pretty warm fuel.) Though I've never seen this done on smaller vehicles, just large equipment.

One system we had for starting heavy equipment out in the middle of nowhere where plug-ins were difficult if not impossible, was with waterline hookups. We had a gas truck with an oversized radiator and quick connects to the equipment radiators. Nose the truck to the rig, connect the waterlines and let it circulate for several minutes. That would warm the big rig up enough to start, then it's own water temperature would keep its fuel warm and it would run all day at 20 below on straight number two. We'd add a little power service to keep the fuel from geling in the lines, but not sure it was even needed. Take the lid off the fuel tank and it would steam.

But, that's just chatter. Not of much value on the smaller rigs unless a person wanted to do a lot of plumbing. Including cutting into the fuel tank to install the loop.

We call the tank coolant lines "Artic Fox" in trucker talk. Tough job on a car or pickup, though.

Webasto is a slick unit. Cold started a truck at -43F with it. Engine water temp was 100F with the Webasto running about 1 1/2 hr. Had #1 in tanks with a Detroit engine and the fuel was still cloudy after 30 min! A gal of unleaded gas per 100 gal kept the truck running, -45F when I got on the road. Had to troll around the yard to get the trans, diff, steering and wheel bearings loosened up. Not a day to break down on the road. Webasto C/Z unit is made for pickups and autos.

Over here, an old Cat engine will gel even with artic foxes. They don't return enough fuel and the return line gels. Cummins and Detroits return more than they burn, and once they start they'll go without an artic fox. Had a '95 Pete with a new style Detroit that returned so much fuel that I had to loosen the fuel caps to keep the tanks from oil canning. Tanks were hot to the touch in the summer. Got great mileage with that hot fuel and the Webasto to reduce the idling.
