Here is my tank, an RCI tank from Summit It fits in the space in front of the wheel well still allowing use of the full 4x8' bed for things like my camper.


And the heated pickup inside:

Im using a 55 gallon plastic food drum, on its side in the back of my van, It has worked out well.. Need to make a holder for the drum so it doens't roll around.. thats the plan this weekend.

I use the bung holse for my inlets and outlets and made a heated pickup/tank heater that lays in the bottom of the tank.. this is surrounded in pipe so that my heating is only heating the VO in the pipe not the entire tank.. any oil that gets to the fuel pickup in the center of this pipe has had to travel through and around my heating tubes for a foot before it hits the pick up. Same principle as some of the commercial tanks avalable where they make essentialy a little tank in a tank where the pickup sits..thus only heating the oil in the mini tank within the tank.. makes it more effiecient. Especially when you have a tank of 50+ gallons like a 55 galon drum, it would take a long time to heat that up.

The bottom bung has been replaced by my heated fuel pickup device just fits through the bung and lays on the bottom of the tank. its sealed to the drum with sealant to prevent any leaks but can be removed for maintance, you just need to re-apply sealant.

The top bung is my fuel full port, where i fill the tank.. just used the 3/4" threaded knockout int he existing bung plug.

It was actualy pretty easy to construct, took about 2 hours total. JUst need to fab a mount for the drum out of some stel and bolt it in the van.

I use a surplus Navy powder keg. It fits into the spare tire place on my suburban. I have a home-made heated fuel pickup made out of an aquarium heat-exchanger that sits around my pickup tube. The tank holds about 17 gallons, and it has a huge opening on top that seals up tight with a twist of the locking mechanism. This also makes it easy to fill from jerry-cans whilst on the trail.

next car i am doing is an '00 jetta. i'm considering using the entire spare tire well as the aux tank. i would seal like they do airplane wings that have fuel inside and use the skin to contain the fuel. then i would make a top that covers the whole area. on 3 sides there is nice shelf and i would add an angle along the back

comments?

How do they seal airplane wings?

Does fiberglass hold up with VO, that would be a easy way to seal it, fiberglass and resin.. sealed perfectly... It's should hold up, VO is pretty dossil as for chemical makeup... doesn't eat plastic etc. I would really go heavy on the coats of resin to ensure 100% its sealed.

There is much discussion on fiberglass tank builiding in here. A search should turn it up.

If you find one you like then put a link to it in this thread too.

there is a compound called pro-seal

http://www.aircraftspruce.com/catalog/cspages/proseal.php

it can be pourd in and tumbled around to coat all surfaces. the jetta is a bit large to turn upside down, but it can be painted on surface. i have to decide if the paint has to be removed first.

it'll be a nice big tank. because of weight, wouldn't normally fill unless out for a long trip.

I use an accumulator bladder as my tank. It has advantages and disadvantages. I built a wooden box for it to rest in, which works pretty well. It doesn't allow for a fuel tank level sender, but since it is 10 gallons, I never go far enough that I can't open the trunk some time to see how much fuel I have. It is easy to look at it and tell how much fuel there is. I run my coolant lines in a loop under the bladder inside the wooden box with a loop of line near the end where the in/out line is. I got it off Ebay for 37.00 with shipping. It is made by a company at www.accumulators.com

The advantages

-There is no air in it, which decreases my likelihood of polymerization.

-relatively compact and flexible in mounting. you have flexibility in shape and size of the wood box, or whatever material you choose.

-price is competitive for 10 gallons of storage.

Disadvantages

-If you let air in, there is a risk of sucking that air into your system if you let the tank fall below about a quarter full. I have mitigated this risk by installing an air trap on the line that I use to fill the tank with. It is simply an upside down goldenrod waterblock filter.

-You can't simply pour fuel in-it must be pumped in since there is only one inlet/outlet. I installed a T to which I attached a new wash machine hose. This hose is 3/8 i.d., and has a garden hose end. Then I got NPT to garden hose adpaters for my filter, and my pump already has garden hose thread. In the end, my fill system uses all garden hose thread, which is pretty good thread. It doesn't need sealant as long as you have the rubber gaskets and tighten it down hand tight.

-Once air gets in there-it is a pain to get out.(EDIT-7/30/07-I have since bought a little pump from Harbor freight that makes this much easier. It is a marine 12V pump with both male 3/4" garden hose thread and 3/8NPT female thread on both the inlet and outlet. It is a positive displacement pump. So now I can hook it up to draw a suction on the bladder and lift the end of the bladder with the inlet/outlet. This way I can pump the air out of the bladder. I've now gotten al lthe air out, and since I fill through an inverted goldenrod filter, which traps air bubbles, I don't have to worry about air in my bladder again.)

If I think about it, and have time this weekend, I'll take some pictures of it along with my nearly finished veggie processing infrastructure and post them all.

Oops, missed this one. It isn't galvanized, it's some other something-or-other military coating that looks similar. I can't remember what it is called though.
