Pre-Heating Engine Diesel Fuel in cold weather
 

Pre-heating your diesel fuel dissolves paraffin wax crystals (and ice) that form when diesel fuel is chilled.

Pre-heating your diesel fuel enables filters and water separators to work more efficiently.

Pre-heating your diesel fuel prevents fuel filters from plugging with wax and/or ice crystals.

Diesel Fuel Pre-heater

Does anyone have dealer/retailer info for any of these?

I really like the ATG/Diesel Therm in particular.

I actually have a NOS 12v Bosch diesel preheater, thermostat controlled, packaged as a Renault part but it's a long tube and I would have to cut back part of the metal supply line to install it and that didn't sit right with me....

Correct
 

Thanks for pointing that out.

The newer engines = everything made after the OM617 has a small fuel pre-heater.
Please note:
The factory pre-heater is not adequate for extreme/arctic conditions.

If you live in a far northern state, Canada or Alaska, additional pre-heating may be needed.

Examples:

Bemidji, Minnesota
Stats: Average temperature during winter months are −30 °F (−34 °C) to +10F.

Thanks whunter, I should have navigated the site a wee bit more before I asked.

Here is their pricelist for ordering direct from the company:

Preheating
 

Why not just use Howe's?

Anti-Gel works excellent in the trucks, and although I had trouble starting my car unless I plugged it in while in Fargo in Jan/Feb, the problem was not with the fuel, which was religiously treated with Howe's anti-gel that I bought at the truckstops, or you can buy Diesel #1.

The wrapping of 3/8 copper tubing around the upper radiator hose done on a pipe form and slid over the hose. Was an example of pre heating the fuel on a vegatable car I changed back to diesel.

There might even be a slight milage gain by using prewarmed fuel in the winter. It was neatly done on that example. Looked like he used a whole roll of that 3/8 soft copper. Would not be hard to duplicate..

To neaten up this one might take a section of larger hose of some sort and slide it over the coil. This would also tend to trap more heat in between.

From the pics, it looks like a glow plug heater in a banjo fitting with a thermostat. I wonder what wattage is the heating element? I don't like it at all since the heat density must be very high. It'd be a lot cheaper and you'd get more gentle heating of the diesel fuel if you place a 1 foot section of 5/16 aluminum tubing along the upper radiator hose and wrap a towel around it for insulation and re-route the fuel line before the diesel fuel filter to the aluminum tubing.

Edit: It's a 200 watt heater, which is very close to what a glow plug puts out. It's $250!!!

I had a better idea........moved to Florida.
