I am buying a 75 gallon auxiliary fuel tank for my 6.0, what is the best way to move the fuel from the aux tank to the main fuel tank in the truck.
I hear gravity is not legal.
The trax ii system seems interesting - will it work with a tank that is not from transfer flow?
(I'm really looking for something not too expensive)
Could always install a switching mechanism like the trucks that have the stock dual tanks. The best feeling in the world is flipping that switch and seeing the gas gauge rise again. The worst is flipping it and not seeing the fuel gauge rise.
I just bought a new 91 gal tool and fuel combo box http://www.rdsaluminum.com/fueltoolboxcombo.html
and plan on installing it in a week or two. I plan on taking pics and doing a write-up on the install. This will be the third one that I have installed. I just use a 3/8 x 6 inch steel brake line and bend it 90* remove the filler neck and drill a hole into the steel part and braze the fuel line in. then I run 3/8 rubber fuel line to the pump I buy from Napa http://www.napaonline.com/MasterPages/NOLMaster.aspx?PageId=470&LineCode=NFP&PartNumber= P4070&Description=Fuel+Pump+(Univ.+In-Line+Rotary+Vane+Type) that we have alot of success with. We used to use a cheaper pump, but they never lasted long. The cheaper ones don't like to suck air too much and that what kills them. Your gonna suck air when you get to the bottom of the tank theres no way to get around it (unless you want to leave 10 gallons or more in the tank). The Napa pump has a lifetime warranty, but we have never used it. One of my dad's drivers uses a holly pump out of one of his race cars. I will let everyone know when I have the write-up finished.
This set up costs about $130 total with all the wiring and switch.
