My temporary long range fuel storage.

[EricBu12]

With the 60 Gal I have replaced underneath (Aero D-60) which has been performing flawless. . I have added a couple removable tanks for the times like this summer, fill in Las Vegas, and can go into LA and back out without fueling in $$$ california.



The left tank is 17 gal. . the right one is 24 gal. . so all total, I have 100 gal on board. . about 700-800 miles range.

The primer bulb pulls fuel from the tank and it siphons down to the 60 tank. . I have a valve to prevent overfill the 60 so it should work pretty well. .

If you are depending on gravity or vacuum to pull your siphon once you have it established with the primer bulb, it should work until one of the tanks sloshes or goes empty and allows air into the line. Then you are done.

or goes empty Then you are done.

Purpose accomplished, right?

EricBu12, what has your MPG been carrying that extra weight when full? I like to fill my 52 Gallon tank, when I re-enter CA and at 22K GCVW have about a 500 mile range depending on the terrain. I hate California taxes and always fill my tanks before re-entering, but with a lot of fuel on board as in your setup has, isn't there a loss of MPG due to weight?

When you are towing Abigail fiver(wind sail) I doubt it will be measurable

Gas/fuel goes up another 3. 5 cents in July here. Wyoming's going up a whopping 10 cents.

100 Gal verses 35 gal. . ok, that is 65 gal. . 65 x ~7#/gal. is 455#. . The weight of a couple of Dudes. . with beer!. . lol

I have had the 17 gal for a while now and have used it a few times. . the clear hose is for me to see when it flows. . I am going to put a couple other small valves in the separate lines to draw off one at a time. . when the 17 gal empties, it don't leave more than a small slosh of fuel. . good enough. .

I have an aluminum 75 gal tank mounted in my box normally but had to take it out to fit a 9'9 camper for my trip to Columbus. I didn't find the extra weight ( about 550# ) a problem as the savings of buying fuel where and when I wanted was worth it. Of course when you go to buy a 110 gals of fuel it is a few $ I see the tanks have sending units on them. I added a cab mounted fuel gauge so I could tell how much was left. Shad

I have a 105 gallon steel bulk tank with transfer pump in the bed. There is such a slight difference in mileage from when the tank is full to when its empty that its hardly noticeable.

No, not really. You can have fuel slosh from terrain or braking or just going around a curve. You could have as much as half of the fuel still top side when air is introduced into the siphon flow. If the fuel line is connected to the bottom of the tank, you would not have any problems. I use a fuel pump off of the draw straw in the top of my transfer tank. I also have a glass fuel filter in line to observe when the tank goes dry. it does not take much to introduce air into the fuel stream when the fuel level gets done to 1/4 tank.

I agree with your thought process here if the siphon line was only slightly longer than the depth of the tank, a quick shot of air and it would stop. However if the siphon line is 4 feet long a quick shot of air would not bother the flow. I can see about two feet of line above the bed, how much is below the bed is hard to say. If he fills the main tank at the fill spout he would probably need at least two more feet, so four feet of down line v/s about a 12" tank depth gives you a 4-1 advantage in the case of a shot of air. Not an argument, just discussing possabilies here, "a what if":-laf

I have a 110 gal tank in front of bed of the truck. it is a farm tank with out baffles and I feel no slosh at 1/2 or 1/4 or 3/4 I have polled all over the west south and mid west my 3500 is a dully.

If you look at the pic at the top, there is a loop of hose for a vent on the 60 gal// toward the rear... . it "T's" into there. . so there is a significant amount of hose to get to the tank... it works though and like I said, I stop, and open the valve and prime it, then have lunch or a whatever an it either does all of it by the time lunch is done. or if not, i can reprime it later to finish. .

Getting a mechanical sight gauge for both tanks to see how much is left. . also I can shake the tanks to hear the slosh.
