I haven't posted for a while so here's the latest..................

FYI: I used the trace heater on the final veggie hard line and not on the hard injector lines.

So just to recap here's the layout in a nutshell:
1) Aux. tank mounted above rear axel with a HFPU (Coolant heat) and an electrical heat pad under the tank.
2) FPHE (coolant heat) feeding to a Racor
3) Racor with an electrical heat sleeeve to 6 way GC valve via SS hard lines that lay across the FPHE and then follow across the top the firewall and go in the valve.

I recently started getting temperatures from the 'common' line just before the stock filter using straight diesel fuel and it was only getting to just above 100 F. So I insulated more lines more thoroughly and it can get up to 120 F.
120F is not high enough in my opinion so I insulated the veggie filter and switched the coolant routing from the hot side to the veggie tank to the HFPU and then to the FPHE to..........
hot side-FPHE-HFPU; still no higher than 120F.

It appears I have A LOT of insulating to do as the probe in the line immediately after the fPHE was getting temps. over 140F and as high as 160F.

This is surprising to me but maybe I'm naive. I thought I was going to be too hot and have to turn off my electrical heaters!

If anybody out there has some experience and can see something I haven't by all means chime in.
