Contimplating installing a fuel heater....
My friend had both a 2005 and 2006 Jetta TDi. Both have fuel heaters under the passenger side. The 2005 seemed to get the fuel, filter housing and even tank hot after 15-20 minutes of driving. The dimensions of it are 6" by 4". Plenty of room to mount pretty much anywhere. I have to try to find out the specifics of it: power draw,etc, before I do it.
Question: Will the 4 rubber lines and the plastic primary filter stand up to heated fuel ?

Yes the fuel lines should hold up to heated fuel to a point, I wouldn't count on that plastic pre filter holding up to the heat though.

Running WVO, doesn't it get heated and run thru the primary ?

You would be miles ahead of yourself to get a second filter houseing (spin-on) installed, and basically a complete second fuel delivery setup (at least to the IP). That way, if something DOES go wrong, you diesel setup is still reliable. This is assuming that you are trying to run veggie (not sure if this is what you are getting at). I recall someone having a sight outlining his two-tank system, that looked to be very reliable. To heat his filter (again, spin-on), he incorporated a coil heat exchanger into his coolant system. This HE was basically 1/2" copper water line, bent into a coil. It looked like a good idea. As for the fuel lines, HIH or HOH is the way to go. Be more specific in what you are looking for, and others here will help you inovate. Good luck!

Some run heated WVO thru the primary and I have not heard of a problem with it, but I would guess there is a limit to what it could take. Probably varies with brand of filter too.
If you are talking about running heated lines with straight Diesel, I don't think you'd want it too hot anyway. Probably not more than 150-200F or so. I'm sure 100F would be plenty hot. Seems like you would run into a vapor lock at some point.

I was thinking the same principle of heating veggie oil only applied to diesel. As I stated in the OP, the VW TDi's heat the diesel so I was thinking that heating it would possibly increase mileage.

To an extent, but there is a recent thread here about someone having a rough idle while using heated diesel.

Not sure how applicable this might be but I installed a couple of electric heaters (ni-chrome wires) on my fuel lines and am pleased with the results. Used the Fatty Wagon kit for the big fuel filter. Was concerned about putting heat on the pre-filter, so I replaced the fuel line about 8" before the pre-filter. Wrapped that metal portion of the line with heat wire. Both heaters reach about 200 degrees F. Of course the fuel doesn't get that hot, as it's just passing through. I use this setup for running bio, but have run D2 through this heat and it has done well.
