It's so nice to have this much fuel capacity. No more range anxiety when pulling the 5th wheel. And you now get to watch me install it!

It can. I notice the float valve in the fill neck is not really a float at all, it's a roll-over valve to close the fuel if the vehicle rolls over. When I got it I made it always open to gravity feed. An old one I had a while back on another truck worked great like that. These new ones do not. It will keep filling until it starts to drip out. I now have a manual valve and a 12v electric valve to open and close it when I need it. So far that has worked great (if I remember to turn it off).
@@SeidelRanch, what electric valve did you end up using? I'm planning on doing the same to my truck, but I don't want the fuel to spill out because my filler neck doesn't close.
What tonneau bed cover do you have? I have the RDS 64 gallon tank and pull a 5th wheel and am looking for a cover that will give me access to the filler cap and also not interfere with the 5th wheel when towing. Thanks
My auxiliary tank has a draw tube so I believe I need to put in a fuel pump. Would I still need a shut off valve if I have an electrical switch and a draw tube?
So yours does not have the drain plug to feed from? If you have a feed tube on top, it will need a pump and probably a shutoff to keep it from syphoning the fuel with the pump off.
Gas has different requirements than diesel. I think this tank can carry both, but please check. Gas expansion is much worse with gasoline. Also, pumps have to be different.
My plan was to do that, but some logic in my truck keeps making it think the fuel gauge is messed up, and then it just shows empty. Since then, I added an electric valve to turn the flow on and off. That way the fuel gauge in my truck works right. I press the button to fill it, then press it again to turn it off. Works great.
I have a gravity fed fuel tank in my one ton truck. Aluminum tank L shape with toolbox. Use it for work and drive down a lot of gravel roads and access roads for the oil patch. A lot of bouncing as you can imagine. Placed my tank on a piece of plywood and the mounting brackets onto hockey pucks. Forgot I had the valve on to fill my truck from the slip tank. Which overfilled my fuel tank and spilled out the vent ontop of the fuel tank (truck tank) My tank isn’t 2 years old and it’s leaking already. Found that out today.
Actually, I have found that auxiliary fuel tanks seem to be cheaper than transfer tanks (at least when I was searching for mine). That said, it's not usually by all that much. Either one will work as an auxiliary tank really, but an aux tank usually has a gravity feed bottom port to drain from and a transfer tank usually has two ports on top. Mine could be either really, because it has a bottom drain port and two ports on top. If you have the bottom port, you can gravity feed from it which makes the setup a little cheaper and easier to install. But if you don't, you can still usually install a small 12 volt pump on it to feed your main tank.

Been thinking of doing this for a long time man. Just got a new truck and I think this will be my first upgrade. Hate filling up every couple days.
Works awesome. We burn a lot of fuel pulling the RV. This gets us much further.
Great video man! Thinking of doing this myself.
It's been great to have.
Great install. I had the same thing happen to me after my install. Can you send me the link to the electric valve you used? Thanks!
I bought this one: amzn.to/4b9eKF5
You to have some support under the tank a plate or rubber mats.
I have some foam weather stripping I put to lift it just a bit off the bedliner.
So what keeps it from overflowing? Is there a check valve somewhere?
Yes. The part that connects the auxiliary tank drain hose to the truck's main tank fill hose is a float valve.
@@SeidelRanchcould you provide a link or part number for that check valve? Please and thanks!
when using the auxilary tank does your truck gas tank overflow at all?
It can. I notice the float valve in the fill neck is not really a float at all, it's a roll-over valve to close the fuel if the vehicle rolls over. When I got it I made it always open to gravity feed. An old one I had a while back on another truck worked great like that. These new ones do not. It will keep filling until it starts to drip out.

What size home did you drill
I believe it was a 3/4" hole to fit the rubber garment and hose.
What tonneau bed cover do you have? I have the RDS 64 gallon tank and pull a 5th wheel and am looking for a cover that will give me access to the filler cap and also not interfere with the 5th wheel when towing. Thanks

Where can get the tank to buy?
I bought mine on Amazon. I have a link in the description of the video to this one.
What size truck bed do you have? What's the distance from back of bed to fender well?
How much did you pay for the tank?
I think it was about $850. I put a link in the description to where I got it.
@@SeidelRanch Thanks! Much appreciated
Dose it matter if it is gas.or is it the same parts?
Gas has different requirements than diesel. I think this tank can carry both, but please check. Gas expansion is much worse with gasoline. Also, pumps have to be different.
Do you leave the valve open all the time? Im doing this in a couple days and gathering all the info i can when the install is complete.

I know transfer tanks are cheàper, but are they safe to use as aux tank?

It's a rubber grommet, not a garment.
Ah, that's right. The rubber garment is for something else.
