[Vwdiesel] insulating you're fuel filter

[Derek]

I am not so worried about the tank and the lines, things can get rather
thick and still pump.  What I am worried about is having to go rescue my
wife again on the side of the road.  I am convinced that it was my filter
that was starting to plug ( it is brand new btw ).  I have my inline heater
plumbed so that it heats the fuel before it goes into the injection pump.
The heater was a supplemental unit that I had while I was using WVO.  My
thinking is that the fuel would be more than warm enough to the point where
that little plastic diverter valve sends all the fuel back to the tank and
didn't recirculate enough to unthaw the filter.  I haven't had this problem
before and I have been using this heater for quite some time now.  For all I
know this is a one time thing with a bad load of fuel.  I am just trying to
think of a way to prevent future occurrences.  I do have an electric
VegTherm heater, but I think that may be a bit of overkill.

P.S. Idling the car on the side of the road did help thaw the filter, but is
was a long drive home.  I kept having to stop over and over again because I
couldn't maintain full power at all.  The gas/kerosene/additive and being in
a heated garage helped enormously.  No issues so far ( knock on wood !! )
