So I just wanted to post up a little experience of mine.
Firstly I have a M1009. Added a second tank (32 gallon) in the engine compartment. Then have converted my truck to run on the two tank system. I have run it on ATF, WMO and WVO. Have clogged off one filter running mainly a mix of 5 month old filtered WVO and WMO combo. Have choked out two times recently for switching over too soon. I start the vehicle on Diesel and then after a sufficient warm up time I switch over to the secondary tank and then purge the system to finish up on Diesel so I do not build up poly in the system or have incredibly hard starts.
My system would automatically switch from diesel to the secondary tank when the engine hits temperature but my switch is busted and I am waiting on a replacement.
I have a single fuel pump which pulls through both the diesel and the alt fuel filter. The valves which switch between the two default to Diesel so that if the system fails it fails into the diesel mode. Down fall of the system is that the pump pumps directly into the engine rather than through a filter and thus does make for a nice rich plume when I start things up. Have yet to have to change out a diesel filter so not sure how the whole system prime is going to go seeing how I will be pulling uphill through the filter to the pump rather than pushing uphill.
First filter clogged off after about 400 miles but as said before I was running straight crap through it
I run WMO and ATF straight from the vehicle. WVO I collect and run through a 200 micron screen filter then into a 55 gallon barrel which I heat to 300 degrees for 24 hours to evaporate off the suspended water. I let the system settle for approx 24 hours then pump off my WVO and dump it into my spare tank.
She smells great running on veg. Have had two people stop to chat after they saw me pouring fuel into the engine compartment. But Everyone who sees my big tank in the engine compartment when I work on it asks what the heck it is. They love it
While I admire the inginuity and fab work you have I find the fact of having 32 gallons of any type fuel in the engine compartment disturbing.
In a frontal impact collision at moderate speed there is going to be a crushing effect on the front end which will likely result in the tank being crushed and the fuel spewing onto the hot exhaust manifold. If the fuel is heated it will result in a lower combustion point and could explode.
Also there are two batteries mouted up there.....same issue....a spark from shorting cables could cause the same effect.
I have seen this happen to commercial trucks.....the fuel tanks collapsed in a collision and the diesel vapors ignited.
Diesel and other high oil fuels burn hot...much hotter than gasoline....I have seen big rigs burned to the point that only steel was left due to the high temps.
I often use waste veggie oil that is too contaminated for fuel as a fire starter....it will kindle green wood in a few minutes. It burns that hot.
This was a Freightliner with a Detroit 60 series with a very tiny fuel leak - he was headed to get the tractor repaired to pass the FHWA inspection.
As you can tell - he did not make it. This was an owner owned tractor and was advised to park it and get a mobile service to come and repair it before it was moved - drivers are smarter than mechanics and this is what he wound up with - a worthless tractor.
As I am a visual person - having a pic to make an impact is priceless.

ARGH. Defintely going to have to rethink this one. Stupid lack of planning. Part I wanted to avoid was a tank full of HEAT in the truck. Now a refab with a tank under the vehicle is looking much more appealing.
PS thanks for raining on my parade ....but at least I still have a parade rather than it being burned up in a hot fireball that the firefighters wont put out because of tons of oil.
Good deal...we would hate to see you make an ash out of yourself.
If you check aftermarket parts suppliers (JC Whitney, etc) you might find an add on tank that will fit under the vehicle since the M1009 is basically a Chevy truck painted green and built to mil specs.
Instead of the second tank, maybe look into producing bio-diesel. If you are already heating the WVO, you are part of the way there. I run it 100% in a M1009, 04 Dodge, Cat 953, farm tractor, etc., etc. Everything I own that is diesel with absolutely no problems, no clogged filters, or having to switch back and forth between fuel sources on the fly.

Yeah heat is the big problem and thus my dual tank set up. When it gets to being all white outside things sludge up pretty bad. For some reason the idea of not cleaning my system out on standard fuel makes me nervous. I wish I had the ability to constantly use a block heater during the winter but just not feasible between work and where I have to currently park. thought about getting one of the fuel powered heaters but opted to stay away from it.
Running everything
Your limited in a m1009 for locations to install a second tank, i'd perosnaly rather see it mounted under the truck and away from any ignition point.
