Installing Aux Fuel tank in Bed of Ram 3500 Dually.

I am installing an 85 gallon aux fuel tank in the bed of my 2005 Ram 3500 dually. It will feed thru a 1/2 hose with an inline filter to the fill tube of the stock fuel tank via a manual shutoff valve....

I have a 60 gal RDS gravity feed. Mine has a vent tube on top of the tank. I ran a section of fuel line from the vent to the under side of my truck. It is bent much like a P-trap thus allowing air in and not anything else. However you do it your tank needs to be vented to work correctly.


This is how mine is set up as well. Works great!
