VW uses a heated fuel filter in the TDI, not sure what temp they run it at tho, I suspect that using engine coolant you are never going to get the diesel fuel to hot and cause a problem, you are still going to need to heat your veggie tank just so you can pump it up to the engine, otherwise in the winter you are going to get solids in there.

First off usually the changover/circulate is before the filter but if it isn't it means that you will get cross contamination into the diesel tank which will eventually crud up your motor.

Second most people who do dual tanks remove their fuel lines to the veggie tank and route them through a larger coolant line off the block (like a jacket around the line), Usually you coil coolant lines around the veggie tank and insulate it then send the coolant back up. In this way the oil is being heated in the tank and heated as it comes on its merry way up to your motor.

Then after all this you would want your in line heater to raise the temp up a bit more just before it gets to the engine. This is the length you will need to go to run veggie in a non tropical climate.

Good Luck

A few people I know have heated not only their filters but the lines between the pump and the injectors.
Somebody (forget who) sells electrically heated injectors. The elc heats them hotter than coolant temps.
I can't remember if it was for VW TDIs or Cummings..........
So far I have only heard of positive results.

On the tank heater:
A guy I know made a metal coil he put around the pickup tube. He ran the coolant through this instead of going around the outside of the tank. He said it helped the warmup time in the Georgia mountains.

I can't understand why my MPG's are so low..........

Here you go.


However, since injectors are located in the cyl. head (a giant heat sink) and heat moves from hot to cold, the cyl. head already does this for you once the engine is up to temp.

As to your original question.

No, it will not hurt to pre heat the diesel to 180 degrees.
