Honestly I wouldn't bother with a hot setup like I built. I should have updated the thread. I had nothing but VP44 issues when I did this. The VP44 users the fuel to cool the computer on top of the engine. After I stopped running the hot fuel, no more problems. The VP44 just doesn't like it.

I'm not running it.

You shouldn't have an issue with your P pump though.

Alternatives??

Is there any way around cooling the VP44 with fuel? How bad were you're problems?... it seems from your initial posts that you ran this system for quite some time before you gave up on it.

Nope, the computer for the VP is built onto the housing. If you could get a special pump built with a long ribbon cable for the internals to the computer then possibly. I ran it for a couple of tanks but kept getting P0216's from the heat. It runs fine on diesel though with no codes.

Just an update, I'm not running much WVO anymore so I've turned the heated lines off. (Ball valves are nice!) But I'm still using the tank for my Jet A/2 stroke/WVO blend. I was having issues with the trash the draw straw was picking up. I had swapped the filter thinking it was simply clogged a week ago. It helped, but I still had issues. So today I pulled the straw out and picked the metal screen out. It was nasty!

Now I didn't simply just put everything back together. I installed a 3/8" fuel filter you get from the parts store before the fuel pump. This will help the pump live longer. And it'll give the $20 fuel filter a longer life as well.

I'll give a drive report once I get home. But with how fast the pump pressurized the system, I suspect it's a great improvement.

I'd recommend any of you to install a cheap filter like this prior to your fuel pump. $3 every now any then is a lot cheaper than a fuel pump! Plus it's gotta help stretch some life out of your main filter.

Not running all that much WVO since the VP44 isn't a good candidate for it. I'm thinking about trying it again with a 75% WVO 25% Jet A blend hot.

What ratio and you're also a CRD and don't have to live with the VP44.

Maybe this is old news . . . the thread sure is.

I saw where some others had traced the code problem on the VP44 down to particles in the WVO larger then 2 micron. Claims were they once a 2 micron filter was used, the codes went away, and the VP was happy from then on. Has anyone else had this success?

I am intent on swapping my '01 Dually over to use free fuel to tow the race car around the Midwest. Should make for a much cheaper race weekend.

The VP44's life is going to be cut short if you send 170+ F WVO through it. No way around that. Unless you plan on cutting the WVO a lot with something and run it non-heated.
