Liquid Transfer Tank for aux fuel tank?

[JGrefenstette]

has anyone ever used a liquid transfer tank for an auxillary fuel tank. i was thinking about the possibilities of getting one and just connecting a fuel line to the existing tank with a on/off valve, so i could refill the tank when ever i needed. it says on most descriptions of the tanks that you MUST NOT connect to any fuel system, and that they are ONLY for transfer, but after all, it is diesel were talkin about here. it aint exactly gonna blow. so i was wondering what yall thought, and if any of yall got some experience doing it er somthing of the sort. thanks

Yes

DOT regulates tanks above 100 gallon. Those below not.

I have 50gl tank, electric pump feeding tee at 1/2" ID vent tube. travel about 600 miles, flip switch and fill tank. Recommend ignition feed exciter source on relay to pump, to prevent spills when forgetful at stops. While I used a simple flip switch, I wish I had used a flip latch safety switch.

My 85 gl total lets me tow at least 900 and up to 1200 empty. That is one-fill up daily at my leisure.

oh good. i was thinking of the delta 36 gallon vertical so this should work. also, do i need a pump, or can i just tap near the bottom of the tank. and gravity feed to my existing tank. i was considering using a standard on of hand valve, so i could simply reach under the bed and flip it untill the tank is full. thanks

If you ran the hose from the aux. tank to the main, relying on gravity, could you run the hose into the tank and let hang 3-4" inside it? That way you wouldn't even need a switch? It would just "self-level" as you used fuel from the main. That way no valves or pumps would be need, therefore simpler install/less parts. I have no experience here, just a brainstorm. Anyone out there see any flaws in my theory? If not, I might try something similar...

thats a good idea, however, i was wondering if the weight of the 36 gallons coming through the line would be to great and cause it to overflow. the tank is 5 feet long, 9 inches wide, and 2 feet tall, so the weight coming down on the fuel line would be pretty good. its still a good idea though... . anyone know if it would work?

I have a 22 gallon cell, gravity feeding into my main tank... I haven't shut the valve off in over 3 weeks now... haven't lost a drop... I also have a pump, but my setup isn't pulling off the bottom of the cell, so I need the pump to start the siphoning effect...

I know I read of several guys running gravity feed setups that never shut them off without any issues.
