Hi Clay

This is where I show my ignorance but I thought there was a lot of discussion on this or other sites that heating the whole tank is not a good idea and could accelerate polymerization. Can you comment or correct me if I am wrong?

Thanks

Back in high schoolI worked for the company that casted the parts for arctic fox very good stuff

Clay, on your tank, other than the hotfox, do you have any other heat source? IS the outside of your tank Hot, warm, cool to the touch while running?

The whole tank is going to get hot eventually, so as long as your using aluminum instead of steel and have no copper fittings inside the tank, Polymerization won't be an issue.
Yes it is a waste of time trying to heat the whole tank IMO...my setup works just fine with the heated hotfox.
The fact is winter time is the killer here with tank heat. Depending on the qualty and type of oil your using, more heat MAY be needed in cold climates. PH oils will turn hard solid at around 40* and at 0* ....well, you get the idea. So in that case a tank with more heating surface inside would be benificial. If you don't know what PH oil is, ...remember the solid white shortning that probably your grandma used to fry chicken in and she had to scoop it out of a crisco can? That is Hydrogenated shortning and Partially Hydrogenated means its half shortning and half oil or some combination thereof.
I use oils that get kinda like jelly at 20* but they don't turn solid persay. So my hotfox can melt it just fine.
The reason i say the whole tank will get hot eventually is...for one summer time heat and the tank is setting in the sun - that can get it up to 110* by itself. Second, there is a regulated return line going to the vegi tank returning unused fuel just the same way your diesel tank is set up. The unused fuel has already been heated to 180* so my return line is aiding in heating the whole tank. If i drive a long time the entire tank will become hot to the touch...maybe 160*.
And I think that just answered part of the next question.

The tank only has the hotfox and a return line sending hot fuel back to the tank as mentioned above. The rest of the system is also heated...Hose on Hose where the fuel line is bundled together with 2 3/4" hot coolant lines from the tank all the way to the engine, a heat exchanger at the module location and then the fuel goes into the fuel rails in the heads which is a final heat exchanger itself.

Thats a nice tank, and makes me wish that I had a pickup, are there alternatives to the bed box? Specifically, for us Ex guys.

Vegistroke made a 30 gallon tank for an EX once that mounted under the truck. It worked ptetty slick.

I just got off the phone with James from DFA (Vegistroke) and he mentioned that they have a new 50 gallon non-toobox tank available (lower cost option) that isn't yet up on the website. Right now my choice still is the 90 gallon toolbox tank but he just mentioned this new tank in the conversation. You may want to give him a call and see what else he may have available as this new option was not yet updated on the site - who knows there may be other new tanks as well.

To me..... fit and finish is important. I would consider a smaller 40-50 gallon tank if it looks good and fits well. I seldom make single trips of over 500 miles and the few times I do a portable tank in the bed for refills would work just fine. I'd much rather go through the hassle of dealing with the portable tank or finding grease on the road a few times a year than looking at a big ugly tank in the bed everyday of the year. I have no desire to install a big old tank in the bed of my truck that looks like... well, a big old tank.

Looks like I will be getting this tank / toolbox. Any opinions?

Are you getting that tank to run SVO?
