2013 Ford 350 diesel auxilary tank plumbing ??

Have been using the electric pump to fill neck for 11 years. The fuel will sometimes gravity feed to the OEM tank but never to where it flows out the OEM fill cap. Put an inline filter to catch the bulk of the stuff (2 micron).

However if you leave to pump on too long the fuel will run out the OEM fill cap.

I finally put a timer on the pump.

Sorry to post to an older thread, but I have the same need, except I want and easy to remove tank. As I type the truck is full of deer apples.

I have both a manual and electric pump to empty the tank if needed. However does anyone know of a good quick connect fitting, that is dry when disconnected? It should also not be much larger than the diameter of the hose.

Thanks.

Just thinking,why not use a small electric fuel pump with an in cab toggle switch to operate it.Simply pump fuel from the aux tank thru an in line filter directly to the factory fill hose pipe.No having to stop and shut off valves or worry about check valve failure. Just turn the pump on and off from the drivers seat as you watch fuel gauge while driving. Any thoughts? Is this legal?

x2 this is what I have on my truck, works great! I do have a ball valve at the tank, the pump and filter are mounted under the bed and line is "T" into the factory "filler hose".

Sounds like a good setup.Could you explain a little more,why do you need a ball valve at the tank? Will the fuel siphon or drain thru the electric pump when it is not running? or is it just a safety feature to prevent any leakage when not being used for a while?
Thanks Ramp

Ball valve is there for exactly as you posted "to prevent any leakage" the costs of environmental clean up, is high and running commercial plates costs are even higher for a "spill".

This works well for me, the pump will deliver 15 gallons per minute

I think that is ok even if you are running gas and are pumping out of the dip tube on the top of the tank.

On my install I not only wanted to do it as economically as possible but simple.I reasoned that if it worked manually it would also work electrically.Having used it I will likely keep it manual as I don't use it often and its not enough of a bother to change it. I do, however, have an electric pump that would be faily easy to hook up.

Lawn. That is a "gravity flow control valve" isnt it??
It prevents over filling of the truck tank i beleave. I want to know if i can just "T" into the breather or filler hose with out over filling.

Not 100% sure but I don't think so. I think its just a ball valve for turning the fuel on or off. The first time I had this done a few years ago, I opened the fuel tank cap and fuel spit out on me. Last time I ever did that.

If I turn the ball valve off, fuel does not flow at all. I can run the truck's tank all the way down but the auxiliary tank stays full. But if I open it, it slowly fills the tank by gravity alone into the truck's filler tube.
