[Vwdiesel] fuel warmer idea and question

[David Cook]

Hey all-

I saw something that mentioned using a VW oil cooler
sandwiched between the fuel filter and it's mount
(just like the oil cooler is mounted on the engine
with the oil filter) as a fuel warmer for veggie oil.

As are a few others on the list, I am mixing diesel
fuel with filtered, used veggie oil in one fuel tank.

I am sure that doing this setup couldn't hurt anything
as far as getting the fuel/oil mixture warmer. 
However, are there any potential problems with getting
the fuel *too* warm?

I know that when doing 100% veggie oil conversions,
the fuel is heated to coolant temps, so I'm guessing
it wouldn't be a problem, but I've read that TDI
engines don't like fuel that is too hot.  So, I guess
the question is: does my 1.6 L engine care about the
fuel being hot or too hot?  Or, if I put that fuel
warmer in, and decided to put 100% diesel fuel in the
tank this summer, could that diesel fuel being warm
hurt anything?

I know that isn't really going to get hot enough to
run 100% WVO in my car, but I think it would help me
run my mix with a little less risk.

Thoughts?

Thanks,

David
