I might be able to get a good deal on a 50-70 gallon aluminum fuel tank from a semi truck. Has anybody ever set one of these up for a auxiliary tank? I am wondering what all it would take to make one work. Would I need a extra pump to be able to use it? Also would I be able to get a wiring kit from Northern Tools and adapt it over to the semi tank?

Thanks
Toby

 

seen a couple flatbed trucks w/ them sitting up against the cab

 

You need to hook the fuel lines up to the top of the tank. DOT does not like the fuel lines hooked to the bottom of the tank. Get a universal Dodge fuel sender to fit the tank (stewert warner I think) , then splice in to the main lines with a 6 port motorized changeover valve. Made by Pollak, part no 42-300 kit. usually costs $55 to 70 depending on the parts store. This kit comes with the valve, switch, and harness connector. It has the electrical connections to change the fuel sender when switching tanks.
Most parts stores can order this part. If you have trouble locating one, contact me and I will help you. I just bought one for my truck to do the same thing. Good luck.

OUCH!

Ya just missed a 140 gallon tank that I sold for $300.
Polished diamond plate aluminum fit across the front of the bed.

 

I have a 100 gal diesel tank on a trailer that I then mounted a 12v pump and meter. Its a great rig for fueling / gassing anything and you can take it with you on a long trip if you want. I've had offers of $500 on it I turned down. I could not build another one for that buying a tank, pump & trailer.

 

Just do a gravity feed into your stock tank.

 

I getting a gooseneck hitch and waiting after that to see how big of a tank that will fit. But I'm going to gravity it into the filler tube. I found a 106 gal tank. Way bigger than my bladder can last!

 

Better put some kind of valve on that so you don't overfill your stock tank. Even a little pump would be cool so you can fill up as you drive and then shut it off when full.
