Is it advisable to heat the fuel filter when running B100?
Here's the background.
I'm planning to start running B100 in my 2003 Freightliner Sprinter RV, which has the Mercedes OM612 5-cylinder 154 HP diesel engine. I plan to travel cross-country, buying commercial B100 where available. TO guard against fuel contamination, I'm considering installing a larger primary fuel filter, upstream of the engine-mounted filter.
I've read that heating the fuel filter will improve its effectiveness with biodiesel. Racor's website recommended coolant heat and 200W of electrical heat, with at least double the regular flow rating.
The filter I'm considering is filter, which was designed for WVO applications.
My plans are to stay in relatively warm weather (above freezing), but colder operation might occur. I'm open to reducing the blend during those periods.
So, would it be useful to add coolant and/or electric heat to the new filter, or would the basic filter be satisfactory?
Thank you in advance for the advice.
